The following descriptions of pathologic changes in pneumonic plague are based upon the examination of small specimens, supplied by Dr. Wu Licn-teh, from twenty-three cases of this disease which occurred during the epidemic of 19 2 1 in North Manchuria. Tonsils.— Eight cases.— Marked hypenemia in all cases. The tonsils were more or less rich in parenclmnatous cells. In some cases the so-called “ germinating centres” appeared greatly enlarged. These “ germinating centres” were composed of large mononuclear light cells, including histiocytes which act as phagocytes. These histioc3’tes, containing plague bacilli, were also frequently observed in other parts of the glands. It is noteworthy that in some cases these enlarged “ germinating centres” were not to be found. A slight inter-cellular deposition of hyaline substance was occasionally observed. The epithelial layer covering the surface of the tonsil appeared in most parts to be generally intact, or at least not destroyed. Here and there, however, destruction of epithelium took place, accompanied by destruction or necrosis of tonsillar cells of the superficial la^er, and an emigration of leucocytes. More or less of inflammatory exudation might have occurred, but no considerable destruction of tissue was noted. Plague bacilli, more or less isolated or in masses, existed in the cavities of the surface and also within the tissue.

Besides the plague tiacilli numerous Gram-positive bacteria were also observed, especially in the cavities of the surface, and occasionally in small numbers within the tissue. While these tonsils showed considerable liypersemia and some necrosis of the cells with inflammatory exudation, the pathological changes were not particularly marked. In comparison with the changes that occur in the lungs and neighbouring lymph glands they were very slight. This condition agrees with that observed in the epidemic of 1 9 1 1 , with one exception. In that case the lymph glands of the neck showed such remarkable enlargement with haemorrhages as to indicate that the priraar}^ infection had occurred in these glands rather than in the lungs. Also the tonsils and surrounding tissues of the pharynx and larynx suffered great pathological changes. None of the present specimens exhibited any such changes as occurred in this particular case. Kidneys.— In addition to the pathologic tissue changes described, plague bacilli in the blood vessels of the kidney and also in the capillaries of the glomeruli were always seen. This was not the case, however, in the lumen of the tubules. In one of these cases a very few isolated Gram-negative bacteria were noted, the morphology of which appeared similar to those of plague bacilli, but it was not possible to identify them as such. In the epidemic of 1 9 1 1 bacilli were found within the rectus tubules in only one case. While the passage of plague bacilli into the urinary tubules may not be impossible, this is not in any sense a usual or necessary feature. The relatively small number of plague bacilli in the blood vessels of the kidney, as compared with those in the liver, corresponds to our observations in the epidemic of 1 9 1 1 . Spleen.— Besides the tissue changes described, plague ba cilli were found to be abundant in the blood space of the pulp. Be tween the pulp cells they appeared either singly or in colonies. They were mostly free between the cells, but a few were phagocyted. Regarding the phagocytosis of plague bacilli in the spleen the speci mens were not suitable for minute examination, and this report must accordingly remain incomplete. But the histological examination of cases during the epidemic of 1 9 1 1 showed phagocytes Morbid Histology of Pneumonic Plague. 619 originating from endothelial or reticulo-endotlieliai cells or histioc3^tes in the pulp. The same condition must have happened in these specimens also. The h-mph follicles were found to contain plague bacilli, but they were less numerous than in the pulp. The bacilli were mainly limited to the surrounding or peripheral zones of the follicles, as very few were noted in the central parts. Gram-positive bacteria in the pulp were found only in small numbers in some cases. Lu n gs.— Fifteen cases. Pneumonic plague causes most im portant and very complicated tissue changes in this organ. Several stages of histological change, from simple hyperaemia, or hyperaemia with slight serous exudation, to severe cellular exudation, were observed. More or less haemorrhage occurred in various parts of the lungs. Haemorrhage within the alveoli in these cases was not especially severe, but erythrocytes in larger or smaller numbers within the alveoli were always apparent. In most cases, in and under the pleura, haemorrhage was histologically very marked. Some haemorrhage was also noted in the interstitium, especially in the interlobular septum and within the connective tissue surrounding the bronchi and blood vessels. At the root of the lung in the connective tissue surrounding the bronchi and blood vessels severe haemorrhage was sometimes observed. Fulness and dilatation of the capillaries of the alveolar walls was noted even in portions of the lung where no plague bacilli were found in the alveoli, or no inflammatory exudation had taken place. This hyperaemia was accompanied by serous exudate which filled the alveoli and contained a few exudative cells, especially leucocytes. In the early stages of inflammation, plague bacilli occurred within the serous exudate 111 fairly large numbers. Where the inflam mation was more advanced the alveoli became filled with cells, polyuuclear cells being most numerous, but which were accompanied by mononuclear cells, the latter being mostly histiocytes and desquamated epithelial cells. These cells in the exudate were more or less mixed with erythrocytes and serous exudate which contained a comparative^ very small quantity of fibrin. The degree of density of cells in the exudate within the alveoli varied greatty; in some cases the cells were loosely arranged, while in others they were closely packed together. In every case the 620 T h e China Medical Journal. alveoli contained dense masses of plague bacilli. In no other form of pneumonia are the pathogenic bacilli to be found in such abundance. It is also characteristic of plague, pneumonia, as compared with ordinary^ pneumonia, that fibrin exists within the exudate only in small quantities. The other important histological characteristic of plague pneumonia is the frequent appearance of hyaline substance in the alveolar walls. The presence of this hyaline material is accompanied by various changes in the walls of the alveoli. Where these changes occur the latter are irregularly thickened. This enlargement of the alveolar walls in one case was due to a hyaline thickening of the capillary walls; in another it was due apparently’ to hyaline thrombi within the capillaries; and in still other cases to a hyaline deposition 011 the outside of the capillary walls or within and inside of the alveoli walls themselves. T his hyaline deposition was also observed in the epidemic of 1 9 1 1 . At that time, in addition to a deposition on the alveolar walls, a similar hyaline substance was observed to radiate out from the walls of blood vessels. In the present specimens a somewhat similar deposition seemed to have occurred, but the radiations were not especially marked. T h e character of this hyaline substance is difficult to deter mine, and in chemical composition it may- not be identical; a part of it without doubt is composed of fibrin. In one case this hyaline substance yvithin the lumen as well as on the walls of the blood capillaries of a number of alveoli was very clearly stained by W eigert’ s fibrin-staining method, while the staining of the fibrin itself in the same specimen was not good. It is probable that this hyraline deposition is caused by the severe exudative inflammation of the lung and, excepting the fibrin thrombi, is a coagulated substance resulting from the exudation from the blood vessels. T h is is not necessarily a specific characteristic of plague pneumonia. T he deposition of hyaline in and on the walls of the ahreoli also occurs, for instance, in influenza pneumonia. G iant cells of bone marrow are often to be found in the blood capillaries of the lung tissue. “ G itterfaser” and elastic fibre showed no distinct changes in those portions of the lung which were not affected by inflammatory exudation. W here marked exudation did occur, however, some diminution and even destruction of these fibres were to be noted. Morbid Histology of Pneumonic Plague. Investigation of the distribution of bacilli in the lung tissue is most important in studying the pathology of pneumonic plague. They are abundant in the alveoli within areas of hepatization and also where the alveoli have discharged only serous exudate. In the former case, where the alveoli are filled with cellular exudate, the bacilli are densely massed in the spaces between the cells. Of this great multitude of bacilli only a few seem to be phagocyted by the cells within the exudate. In some cases the phagocytes for plague bacilli could only with difficulty be observed in the pneumonic area. This condition was also noted in the lumen of the bronchi. Those cells which do act as phagocytes for the plague bacilli are mainly large mononuclear cells, most of which seem, to be histiocytes. To what extent polynuclear leucocytes may act as phagocytes to the plague bacilli is difficult to determine. While plague bacilli are to be found in abundance throughout pneumonic lung tissue, including the blood vessels and capillaries, the greatest accumulations occur in the lymph vessels and lymph spaces of the tissue. The lymph vessels at the root of the lung and those accompanying the branches of the bronchi and neighbouring blood vessels are very often most densely packed with piague bacilli. The pathological change in the walls of the bronchioli, as noted above, where the destructive process was working through from the outside of the wall towards the mucous membrane within, was due to the virus being brought by the tymph vessels along the bronchioli. It was peculiar of many of the blood vessels within the plague pneumonic area that their walls were surrounded by marked accumulations of bacilli. This may be due to some perivascular space which may provide passage for lymph and thus becomes densely filled with bacilli. Very often the wall of the blood vessel itself is invaded by the bacilli, and if this is not too thick, as in the case of the veins, an accumulation of bacilli may penetrate to the interior, where the endothelial cells are destroyed. In this way great numbers of plague bacilli enter the blood stream. These changes in the walls of the blood vessels were also noted in the epidemic of 1 9 1 1. The lymph vessels, greatly dilated and fi lied with bacilli, contain also polynuclear leucocytes and some blood. 622 T h e China Medical Journal. While the bacilli found in greatest abundance in the pneumonic areas were almost entireh* plague bacilli, mixed infection in varying degrees was not uncommon. In most of these specimens, Grampositive bacteria, such as diplococci, staphylococci and other bacilli, were noted in the blood vessels and alveoli. The number of these bacteria, however, was much smaller than the plague bacilli. In a few cases the number of these other bacteria was fairly large in the pneumonic area, aud they might have aggravated the pneumonic condition of the lung, but the chief source of pneumonic infiltration, whose manifestations were almost identical in all cases, is due to plague bacilli. Pleura.— In addition to the pathological changes described, plague bacilli were densety massed in the sub-pleural and pleural tissue. Occasionally at points on the pleura rather isolated colonies of plague bacilli, accompanied by some leucocytes, were noted. These patches did not appear to result from the general process of pneu monic hepatisation. Lymph Grlands.— Mesenteric, two cases; cervical, two cases; bronchial, five cases. In the two cases of mesenteric lymph glands hyperplasia of cells, accompanied by more or less hyperaemia, was noted. In one of these a diffused hy'perplasia of lymphoid cells had occurred, while the other case was marked by a proliferation of endothelial cells which had filled up the dilated lymph sinus. Socalled “ germinating centres” in the follicles were not well developed. No necrosis, haemorrhage, or inflammatory areas were observed, and polynuclear leucocytes appeared only in small numbers. Bacilli were not numerous in the blood vessels. Examination of numerous slides revealed no plague bacilli in the tissue of the mesenteric lymph glands. In an occasional slide, among the cells of the tissue, a few bacilli were noted which resembled plague bacilli, but the exact character of the former could not be determined. One of the two cervical lymph glands showed marked hyperaemia and proliferation of the endothelial cells of the dilated lymph sinus. In some of the follicles “ germinating centres” appeared. A s to the existence of plague bacilli, because of poor staining, no definite results could be obtained. It is at least -certain that no large accumulations of bacilli existed, and no tissue changes characteristic of plague were observed. Morbid Histology of Pneumonic Plague. 623 The other cervical lymph gland proved to be severely affected by chronic tuberculosis. A fibro-caseous substance occupied almost the whole gland, lymph tissue remaining only iii one corner. T h is lymph tissue, especially within the lymph sinus, contained small accumulations of bacilli which resembled plague bacilli. Whether plague bacilli can penetrate into a tubercular area is an interesting question. So far as this specimen is concerned, no plague bacilli were found in the fibro-caseous substance. The bronchial lymph glands, being most intimately7 connected with the lung, are the ones which undergo the severest histological changes in pneumonic plague. The entire tissue of the gland becomes heavily infected with plague bacilli. Where these were abundant, the cells of the gland were diminished in number. Cells undergoing necrosis were seen. No marked blood extravasation within the gland was observed. On the other hand, the normal tissue structure of the lymph gland was severely- affected. Elastic fibres and “ Gitterfaser” were less stained and became attenuated or even more or less destroyed. Augmentation of bacilli occurred more markedly in the peripheral zone than in the central portions, and more 111 the lymph sinus than in the lymph follicles and medullarv fasciculus. The presence of bacilli could be noted within the follicles, where they were found scattered among the lymph cells, particularly if the gland yvas severely- infected, but the lymph follicles were alwa3’s less affected by’ the bacilli than other parts of the gland. Often follicles were observed to be surrounded bv a laj^er of varying thickness consisting of a mass of bacilli. These seem to offer more resistance to the effects of plague virus than other parts of the gland tissue, but eventuallythey undergo a gradual atrophy’ and destruction. Infiltration of polynuclear leucocytes into the tissue of the lymph gland occurred to some extent. Sometimes these appeared in fairly large numbers, but no suppurative areas were noted. A limited amount of serous infiltration was occasionally observed, and staining revealed the presence oi fibrin, but only in small quantities. A deposition of hyaline substance on the walls of the blood vessels and the reticulum , present in cases during the epidemic of 1 9 1 1 , may also have occurred, but it yvas not promin ent. In spite of the presence of great numbers of bacilli and some augmentation of leucocytes and mononuclear m igratory cells, T h e China Medical Journal. 624 phagocytosis in the lymph glands could not be clearly ascertained. In some cases no cells carrying plague bacilli could be found. But investigations during the epidemic of 1 9 1 1 indicated that phagocy tosis in the plague bubo did occur to some extent, especially in the early stages of the infection. This was noted particular^’ in the lymph sinus. In those cases the swollen and desquamated sinus cells or endothelial cells, which partook of the nature of histiocytes, acted to a large extent as phagocytes. Other mononuclear cells may* also have become phagocytes. It was occasionally noted, furthermore, that blistered phagocytes which were carrying lymphocytes and blood pigment had also absorbed some plague bacilli. Where the augmentation of plague bacilli in the lymph sinus became ver}’ marked the swollen and desquamated cells and phagocytes disappeared. This is perhaps the reason why in the present specimens, which show advanced stages of plague bubo, phagocytosis is difficult to determine. In those areas where carbon dust had been heavily deposited in the bronchial iympli glands the accumulation of plague bacilli yvas less marked. The relation of the penetration of plague bacilli into tubercular areas of the bronchial lymph glands is the same as in the cervical gland mentioned above. The tissue surrounding the bronchial lymph glands in the root of the lung was alway’s infected with dense accumulations of plague bacilli, and severe haemorrhage was often noted. Lymph vessels near the bronchial glands appeared dilated and filled with bacilli. Numerous leucocytes, lymphocytes, and some red blood cells were also found in these lymph vessels. D is c u s s io n and C o n c l u s io n s . The most important tissue changes caused by pneumonic plague occur in the lungs and neighbouring bronchial lymph glands. In these organs the plague bacilli are most abundant, and the tissue changes which take place are mainly due to the presence of these bacilli. The lungs are affected by hypememia, serous and cellular exudation and more or less haemorrhage. The specimens examined in connection with this report did not, however, reveal specially marked haemorrhage into the alveoli. Fibrin within the alveolar Morbid Histology of Pneumonic Plague. 625 exudate was inconsiderable. Hyaline substance, the origin of which is more or less intimately related to that of fibrin, was in most cases found deposited on the alveolar walls. These tissue changes, together with the enormous increase of plague bacilli in the pneumonic areas, are characteristic of plague pneumonia. The plague bacilli are abundant not only in the alveoli, but also in the interstitial tissue, especially in the lymph vessels and spaces in the immediate neighbourhood of the bronchi and blood vessels and under the pleura. In these lymph passages the plague bacilli are usually found to be most densety massed. The tymph vessels at the root of the lung in the neighbourhood of the infected bronchial lymph glands are likewise always greatty dilated and filled with bacilli. The lymph vessels seem to provide an especial ly favourable medium ior the augmentation of the plague bacilli, and at the same time the}- serve as convenient canals along which the latter can proceed to other parts of the tissue. Examination of the lung shows small areas of plague pneumonia developing in the peribronchial alveoli. The multiplication of bacilli in the peribronchial and perivascular lymph vessels and spaces is a most important cause of this lobular pneumonic infec tion. On the other hand, the spreading of pneumonic areas majalso be due to the inhalation of plague bacilli from the upper and wider parts of the bronchi and bronchioli into the deeper recesses of the lung. In this case the mucous membrane of the bronchioli is affected from within the lumsn and the plague bacilli penetrate from the mucous membrane, whose epithelium is more or less destroyed, into the tissue of the walls. This inhalation of bacilli may also carry them directly into the alveoli. The peribronchial and broncho-pneumonic areas, whilst expand ing, join with each other, thus diffusing the pneumonic infiltration through a large portion of the lung. When, however, the process of pneumonic infiltration occurs over a wide area in a very short space of time its relation to the condition of the bronchioli is not clear. As to the condition of the cervical, mesenteric and bronchial lymph glands in pneumonic plague, it is the latter which are by far the most severely affected both as to pathological tissue change 626 T he China Medical Journal. and the presence of bacilli which are especially augmented in the lymph sinus. The tissue of the mesenteric lymph glands showed only slight evidence of the presence of plague bacilli, and in the cervical glands no large accumulations of bacilli were found. Plague infection in an individual may result in some cellular hyperplasia in these lymph glands. The tonsils are only slightly affected, comparatively small accumulations of bacilli being found, and these mainly in the superficial layer. A STUDY OP THE FAT, LACTOSE, AND PROTEIN CONTENT OF CHINESE WOMEN’S M ILK* E r n est T so , m . d ., Peking. The average composition of human milk as given in most of the older text-books is : fat, 4 per cent; lactose, 7 percent; protein, 1.5 per cent; and salts, 0.2 per cent. The present tendency, however, is to set the average figures for these constituents at 3.5 percent, 7.5 percent, T.25 percent, and 0.2 percent, respectively1. The composition of individual samples may vary within wide limits, particularly as regards the fat content. It is not unusual, for instance, that the fat content at the beginning of a nursing period may be as low as 1 per cent, whereas toward the end the fat may have increased to 7 or S per cent. Of the different constituents of milk the lactose is the least variable. The protein content varies to a wider extent than does lactose and less so than the fat. Denis and T alb o t2 have recently studied the variations of the composition of human m ilk under certain specific conditions. T h ey found, among other things, that the lactose content showed a tendenc}’’ to increase as lactation progressed and to decrease from the beginning to the end of a single nursing. T he protein is known to be high in the colostrum m ilk. It rapidly falls to about its average figure in the transition period when colostrum changes into mature m iik. According to Denis and T albot, the protein content tends to diminish further as lactation goes on. *From the Departm ent of Medicine, P eking Union Medical College, Peking, Study of Chinese Women's M ilk. 6 27 The investigation here recorded of the fat, lactose, and protein content of Chinese women’ s milk was divided into similar lines of inquiry. These consisted of, first, a study of the composition of milk at different periods of lactation; second, a study of the composition of milk at the beginning and at the end of a single nursing; third, a comparison of the milk of those women who nurse their own babies with the milk of wet-nurses; and fourth, a comparison of the composition of milk taken almost simultaneously from the right and left breasts. The samples of milk were obtained from the Children’s Wards and Out-patient Department of the Peking Union Medical College Hospital. A few samples were taken from the wet-nursery of the Peking Foundling Home. The fat was determined by the Babcock method, or, when samples were small, by the Adams-Soxhlet process, or the Babcock method as modified by the author'1. The determination of lactose was made according to Folin and Peck’s titration method4. The protein was calculated from the nitrogen values obtained by means of the usual Kjeldahl-Gunning method, the factor 6.25 being employed. It was planned to obtain one ounce of milk before nursing and one ounce immediate!}- after nursing from the same breast. In a considerable number of cases the attempt was not successful owing to the irregularities in nursing intervals. Typical samples were, however, secured from those women who came to nurse the sick children in the hospital at regular hours. It should be mentioned that onty those samples were included where the nursing babies were either supposedly healthy or had no disease directlj7 due to the milk. Table I contains the results of analyses of 87 samples of milk arranged in the order of age of the nursing child. The average figures are : fat, 3.72 per cent, lactose, 7 .17 per cent; and protein, 1.36 per cent. Attention is called to one instance (last two anaWses in Table I) in which the fat was found to be 8.45 per cent; lactose, 4.1 per cent; and protein, 0.32 per cent. I11 this case the child had been nursed continuously from birth until it was 47 months’ old.* Excluding this case, the range of variations in this series of analyses is ; fat, o.S to 10.5 per cent; lactose, 6.7 to 8.6 per cent; and protein, 0.9 to 2.39 per cent. *There are instances among the Chinese in which the mother nurses an older child when the younger nursling has died. T h e China Medical Journal. Table II illustrates more clearly the variations of the composi tion of milk according to the periods of lactation. The results seem to agree with those reported by Holt and his associates5 and other investigators, in that the fat content is higher in mature and late milk than in the colostrum; that the reverse is true of the proteins; and that beyond the colostrum period the lactose does not tend to vary as lactation progresses. However, Denis and Talbot* noted rather an increase of the sugar content during the course of lactation. Table III shows the variations in the composition of milk from the beginning to the end of a single nursing. As reported by other investigators, there is considerably more fat toward the end of nursing than at the beginning. Variations o f the other constituents are not so striking or constant. In Table IV is shown the difference in the fat content between the milk of those women who nurse their own babies and the milk of wet-nurses. The higher fat content of “ mothers’ ” milk is maintained in the fore-milk as well as in the strippings. A comparison of the composition of milk taken practically simultaneously from the right and left breasts is presented in Table V . The figures seem to indicate that although the milk tends to have the same composition from both breasts, it may vary con siderably as regards the fat content. S um m ary A study of 87 sampies of Chinese women’ s milk shows that its percentage composition differs in no essential respects from the composition of human milk in other countries. Like the milk of Occidental women, the fat content varies considerabl}- in individual samples. It is generally high in the strippings and low in the fore milk. It tends to be higher in mature and late milk than in colostrum milk. Samples obtained practically simultaneously from the right and left breasts may at times be quite unlike in their fat percentage. An investigation of the milk of those women who nurse their own babies and the milk of wet-nurses shows that the former is usually richer in fat content than the latter.

Chemical Purity of Carbon Tetrachloride. 633 “ THE CHEMICAL PURITY OF CARBON TETRACHLORIDE. J ohn C a m er o n , m .p . s . (Lond,), P e k in ". The interesting compound of carbon known as carbon tetra chloride was discovered by Regnault in 1839, but did not come into general notice until December 1865, when Simpson of Edinburgh sug gested its use as an aniesthetic. The medical profession, however, disapproved of its use as an anaesthetic. During the past few years the use of this drug as an efficient anthelmintic or vermifuge has been suggested to the medical profession, and in 19 2 1 1 M. A. Hall found carbon tetrachloride an effective remedy for hookworm in dogs; the dose was 0.3 c.c. per kilo of bod}- weight, He tried 3 c.c. on himself and experienced no bad effects, and concluded that it should prove effective in human beings and safer than thymol or chenopodium. C. X . Leach' reports that 10 c.c. given to a human patient produced no ill effects whatever and completely removed all hookworms and ascarides. The drug had little effect on trichurides and oxyurides. Since these statements were written much valuable work has been done by various investigators in different parts of the world on the use of this compound, carbon tetrachloride, as an anthelmintic. Perhaps the most valuable contribution to the literature on the subject is an article by Leach, Haughwout and A sh:‘ . They state in their conclusions that “ the same care should be exercised in prescribing carbon tetrachloride as is observed in the administration of any potent drug that may work harm in the presence of contra-indications or in excessive quantities ; in other words, it always should be given under competent medical supervision. Doses of ‘ pure ’ carbon tetrachloride, com puted on the basis of 1 cubic centimeter of the drug to each 5.5 kilograms of body weight, are safe in the absence of contra-indi cations. ” “ On this basis we have administered doses ranging up to 12.5 c.c. and even 15 c.c., without observing untoward effects of a serious nature. ” In all their experiments these authors used only chemically pure carbon tetrachloride, and to this end they submitted every shipment of the drug they purchased to a chemist for analysis. In one instance4 a shipment of 1,000 liters was found to contain an excessive amount ol carbon disulphide. During the 634 The China Medical Journal. past two years we have been using carbon tetrachloride in this hospital of the Peking Union Medical College as a vermifuge. Carbon tetrachloride5 may be obtained by passing the vapors of carbon bisulphide together with chlorine through a red-hot porcelain tube, the resulting mixture of sulphur chloride being freed from the former by distilling with potassium hydroxide or milk of lime. It occurs as a heavy colorless liquid, having an agreeable, pungent, chloroform-like odor. Its specific gravity is about 1.600 and it boils at 77°c. In this laboratory during the past year we have submitted samples of carbon tetrachloride supplied by leading pharmaceutical houses in different parts of the world to careful analysis and have had, with only one exception, positive reactions for the presence of carbon disulphide. In June, 19 2 3, a routine analysis on three different lots of carbon tetra chloride was carried out, and in one case the content of carbon disulphide was found to be as high as one per cent. During the past month five further samples of recent shipments of carbon tetrachloride C. P. have been analysed, and in only one sample was a negative reaction shown for impurities. In one of the samples the percentage content of carbon disulphide was approximately one per cent. In three of the samples only traces of this impurity were found, less than 0 .1 per cent. The following extract from the monograph on carbon tetrachloride in the newly, published British Pharmaceutical Codex, 19 2 3, is of interest 111 this connection : “ Carbonjjtetrachloride for medicinal use should not contain more than”o .i per cent of carbon disulphide. ” A s carbon'tetrachloride is likely to become an item which will be carried in stock by most of our Chinese mission hospitals in future, it occurred to the writer that a few notes 011 the methods of ridding this compound of all traces of impurities and of testing the compound for likely impurities might be of general interest at the present time in China. When carbon tetrachloride is intended for internal administration it would seem a wise proceeding, in view of our experiences here, to carry out a test on the sample for the pre sence of carbon disulphide, and if more than the merest trace is found we would suggest that the drug be purified by the method suggested later in*this note. On the other hand, if it is for any reason found impossible to p u rify the drug at the hospital, one of the brands of carbon Chemical Purity of Carbon Tetrachloride. 635 tetrachloride (medicinal) listed in the latest supplement to New and Non-official Remedies, 19 2 3 6, should be purchased.

Most of the commercial samples have a boiling-point of 7S0 C. The details of the method we use in the Peking Union Medical College for the purification of commercial carbon tetra chloride are as follows : 250 c.c. of the impure carbon tetrachloride are refluxed for approximately one hour with an oxidizing mixture. (Potassium dichromate, 60 grammes, and concentrated sulphuric acid to 150 c.c.) The carbon tetrachloride assumes a dark-red color (like bromine), it fumes in the presence of moisture, has a chlorine odor and irritates the ey&s. Decant the dark-red upper layer. Add 50 c.c. of a 15 per cent, potassium hydroxide solution. Transfer to a separator, shake during fifteen minutes. Separate the lower layer, which is now almost colorless. Wash this lower layer four times with 10 c.c. of 15 per cent potassium hydroxide solution and separate the lower layer each time. Wash the lower layer with 50 c.c. .of distilled water divided in two portions or until the aqueous washings are neutral to litmus. Then add 30 grammes of calcium chloride to the separated and well-washed liquid contained in a distilling flask. Shake. Stopper the flask and allow to stand overnight. Distil from a water bath. The distillate consists of chemically pure carbon tetrachloride suited for internal administration. The process of purification is not nearly 63 6 The China Medical Journal. so complicated as it seems and can be mastered by the average Chinese dispenser after one trial in the presence of a foreign-trained medical man or chemist. The following are a lew quick tests which may be applied to a sample of carbon tetrachloride to ascertain its purity or otherwise : j. Shake 10 c.c. of carbon tetrachloride with 10 c.c. of distilled water. The aqueous layer should be neutral to litmus paper and should not give an opalescence with silver nitrate solution. (Absence of chloride.) 2. Shake io c.c. of carbon tetrachloride with 10 c.c. of distilled water containing a few drops of potassium iodide solution. On standing for five minutes the lower layer should not be colored violet- (Absence of free chlorine.) 3. Warm 10 c.c. of carbon tetrachloride with 10 c.c. of 25 per cent potassium hydroxide solution. No yellow or brown color should develop. (Absence of aldehydes. ) 4. M ix 10 c.c. of carbon tetrachloride with 10 c.c. of pure sulphuric acid and shake occasionally for five minutes. Not more than a barely perceptible color should be present in either layer. (Organic impurities). ¿. Mix 10 c.c. of carbon tetrachloride with 10 c.c. of 10 per cent alcohol potash ; allow to stand one hour, acidify with glacial acetic acid, add 1 c.c. of a 10 per cent, copper sulphate solution. If a yellow precipitate appears writhin two hours, the presence of carbon disulphide is indicated. 6. Take 3 c.c. of carbon tetrachloride in a dry tube, add a few drops of a mixture of potassium dichromate and sulphuric acid (1 to 3). Apply heat gently. If the yellowish mixture becomes green while the sample remains colorless carbon disulphide is indicated. 7. The quantitative estimation of carbon disulphide in a sample of carbon tetrachloride may be carried out in the following manner : Weigh about 5 gm. of the sample accurately, place in a reflux apparatus with 20 c.c. of half normal alcoholic potassium hydroxide and the mixture gently boil for half an hour. Dilute the solution with 50 c.c. of distilled water and 5 c.c. of 20 per cent, alcoholic potassium hydroxide solution, warm the mixture on the steam bath Chinese Matena Medica. 637 until the carbon tetrachloride and alcohol have been removed, and add gradually 50 c.c. of bromine water to the alkaline solution. (An excess of bromine water must be used.) After warming for 15 minutes an excess of hydrochloric acid is added and the solution filtered. Then add an excess of barium chloride solution. The barium sulphate is collected, heated and weighed in the usual way. The weight of barium sulphate obtained should correspond to not more than 0 .15 per cent, of carbon disulphide.

CHINESE MATERIA MEDICA (VEGETABLE KINGDOM). B. F . R e a d , Ph. C., M .S., P e k in g Union M edical C ollege, P ek in g. A study of the drugs of the Chinese materia medica belonging to the vegetable kingdom is different from the study of the mineral drugs. The latter consist of ores or chemical salts of definite identity, the medicinal values of which are well known. The drugs of the vegetable kingdom, as pointed out in a previous paper1, may be regarded as made up of : 1. Well-known standard Western drugs. 2. Drugs of near botanical origin which may be substituted for our standard drugs. 3. The remainder, including drugs of potential worth to modern scientific medicine. 638 The China Medical Journal. It is impossible in a short paper to speak of each drug separately*. A general classification along the above lines, with specific information concerning drugs of interest and of immediate use to physicians in China, will constitute the aim of this paper. In a separate Supplement there is a comprehensive Reference L ist' of Chemical, Botanical and Pharmacological literature concerning each drug, compiled by the writer and published in Peking. 1. S tandard D rugs There are quite a number of standard Western drugs in China. Some of these are shipped to Europe and America to be shipped back again to China for use in our mission hospitals. On the face of things this appears absurd, yet it would not be right to condemn such a practice without finding out why. Prim arily, without any doubt, this is lack of reliable information. Secondarily, the price, purity and preparation of native drugs are alwaj's ques tionable. A s to the price and purity, what has been said regarding the price of mineral drugs applies still more to vegetable drugs, particularly- those which are exported from the E ast to countries in the West. No fair estimate can be obtained of the market value in China by simply purchasing through retail shops, though even so the retail Chinese price is as often as not below the wholesale price of the drug from home. The writer recently paid a visit to the national drug fair held semi-annually at Chichow in North China. Here assemble regularly many- members of thirteen caravans from as many drug-producing centres in China. From distant Tibet they bring saffron and sal ammoniac; orange peel and litchis from Canton; mushrooms and huang ch’ i from Mongolia; rhubarb from Szechuan, etc. Myrrh and frankincense are brought to the famous God of Medicine there, as wise men of old brought their treasure to the infant Christ. With the blessings of the gods the Chinese merchants sell their goods, stay several weeks and hold nightly festivals, where each caravan takes the stage in a large amphitheatre and with much acting and music have a royal time. It is possible then, or at any time during the year, to go directly to the warehouses and buy wholesale any quantity of any drug. There is open for inspection bale after bale of crude material. The first remark passed by my colleague, a well-trained pharmacist, was, “ How exceptionally good all the samples appear Chinese Materia Medica. 639 to be.” When it is realized that such drugs as senna leaves appear on the London drug market adulterated ro to 20 per cent, or even 50 per cent, with foreign material, and that digitalis, henbane, and our common leaf drugs are seldom free from a certain percentage of foreign material, the fact that crude Chinese drugs bought on the Chinese wholesale market are exceptionally pure, should induce those interested in the purchase of drugs to give greater attention to China’s products than they have done heretofore. We purchased about $50 worth of material, and if bulk be worth noting I may say it took an extra cart to get it to the station. The prices were most reasonable. Some material for which I had paid $ 1.5 0 in the city shops, I purchased for 23 tael cents per catty in Chichow. First-class Szechuan rhubarb was 26 tael cents a lb. ; splendid orange peel, 46 cents a lb. ; fennel, 9 cents a lb .; gentian, 41 cents a lb. ; catechu, 19 cents a lb. ; leprosy seeds, less than 7 cents per lb. and so on. As pointed out by Drs. Thompson’, Douthwaite4 and others, many years ago there existed upon the China market supplies of pharmacopoeial material in the following lines : Camphor <$$/}[§ chang nao). Asafetida ah u'ei). Cinnamon kuei p ’i ). Ginger root (]!£ chiang) Cloves ( ting hsiang). Rhubarb ("frM ta huang). Orange peel (Mjfe kuang p ’i). My-rrh m m mo yao).

Som eO bsoleleDrugs.— The aconites of China contain aconitine. Were aconite a drug in daily use, one might say much in support of adopting native material. This is true for a number of other medicines which are becoming almost obsolete in our Western practice. It may be well to mention some, for they are still mentioned in Western books, being used as condiments, sweetmeats or foods. Sesame oil Marshmallow (W St) < * £ ) Rose petals (% Logwood ( fM c j Flag root ( 0 H ) Cassia pods &) Calendula Turmeric (H iff) Xutmeg Abrus Verbena Dulcamara ( © 355) Honey f £ £ ; Mulberry Tamarinds Agar Prices and detailed information concerning them are given in the Customs List of Medicines of the Hankow ports, prepared by Mr. Braun6. Preparation.— From practical experience it has been found that the condition or form of the drug is of importance. Large lumps of ginger root are almost useless to a young dispenser who has not learned how to grind up fibrous material to a condition sufficiently fine to suit the requirements of the pharmacopoeia; naturally he prefers the nice-looking homogeneous material which comes from Europe in a nice bottle with a nice label. The drugs above mentioned, secured in the wholesale market, were all in a condition suitable to easy manipulation. The Chinese have a way of cutting these drugs into very thin slices, which, when dry, are quite friable and easily powdered if one has a small grinder like a coffee-grinder or a small powder mill. We have found those made in Philadelphia, U .S .A ., and sold by Arthur H. Thomas, very useful. There is no apparent good reason why all our hospitals should not buy the crude material and make up their own tinctures, infusions and Chinese Materia Medica. 641 other galenicals. For many hospitals in China it would be a great service and of mutual financial benefit if one of our well-trained hospital pharmacists at a port suitable for distribution would take up this work of the manufacture of galenicals from native material. It would be possible to sell the same at quite a cheap rate whilst securing quite a good profit to cover all overhead expenses. II. S u b s t it u t e s The second class of drugs to engage our attention are those of botanical origin similar to our Western products and which have proved to be satisfactory substitutes. The drugs of this group require strict individual attention, detailed chemical analysis and careful testing, so that no mistakes occur by making an unsatisfactory, or a seriously inferior, or an altogether mistaken, substitution of material. A good tincture 01" cardamoms can be made from the cheap Chinese “ So S h a ” or “ Sha Je n ,” Amomum xanihoides. The slight difference iu flavour does not warrant buying the very expensive official cardamoms. In 19 13 there was an interesting article in the “ China Medical Journal ” by Dr. Bowman7, who drew attention to the great use that can be made of Chinese chilies, “ La-chiao,” in making a tincture suitable for many types of internal and external complaints. Externally- it is a strong rubefacient; as an ointment, made by boiling with vaseline and straining out the solid marc through muslin, it forms the basis of electric pain-killers and patent remedies for rheumatism and sciatica. As previously pointed out, the Daturas are common in China ; D. alba and D. stramonium are found throughout the country. Whilst it has not been possible to secure these on the drug market, the}- are easily collected in the countryside, or sufficient ior the regular need of a hospital can be grown without much trouble. Mentha arvensis $f) is the official Chinese “ m int” and may well be adopted for regular use. Other good substitutes may be found in gentian, cinnamon, hydnocarpus, polygala, coptis, and Japanese belladonna. A ll of these have been inserted in the Japanese pharmacopoeia, their adoption being based upon full chemical analyses, usage, and known physiological effect.

O th er C h in e s e D ru g s u sed in W ester n M e d ic in e The remainder of the drugs described in the Chinese Materia Medica lend themselves to a critical study in various groups. (a) Those whose chemical composition and potential worth are well known, which have never received serious attention. As will be seen from the references in literature, this group is quite large, much larger than most people suppose. The majority of Chinese drugs belong to it. (b) Drugs well known in the West which, on account of weak phj'siologicai action, have never gained a place in modern scientific medicine, such as shepherd’s purse, ivy, plantago, violet, bistort, coltsfoot, etc. They are still sometimes used by certain classes of doctors. These drugs are best discussed here, in that they merit investigation in order to test the claims made for them in old works on Chinese medicine. (c) Other drugs which may or may not have been examined by scientific methods. In any case, the normal sequence would be : (1) Satisfactory identification by a trained pharmacognocist. (2) Thorough extraction and chemical analysis of essential principles. Chinese Mat eri a Medica. 645 (3) Physiological testing of same upon all the body systems, tissues, etc. (4) The trial, elinicali}', of those known to be of potential value. The chapter on poisonous Chinese plants naturally suggests itself as being the most likely to mention potent active principles. T his group demands early attention, not only for its promise of therapeutic value, but for the knowledge which is needed of Chinese toxicology and the contribution which modern science may make to render it of service to medical men. The purpose of such research may be defined as : (a) To find a means of helping to meet the great economic need of our hospitals. (b) To discover specifics, or drugs with potent action, useful in the treatment of disease. (c) To add to the sum total of our scientific knowledge which indirectly benefits everything and everybody. So far this work has been very* limited in extent. A begin ning has been made, and some of the findiugs are reported in another paper. Their adoption requires wise judgment and caution. In our enthusiasm for this most interesting subject, care is needed that there be not given too much credit to something which later becomes discredited in value. Overrated claims will seriously set back scientific interest and will delay the acceptance later of worth}7 remedies which may help to meet the world-wide needs of the sick. R efer en ces. 1. R ead .

THE THYMUS GLAND IN THE CHINESE.* J. L . S h k ix sh e a k , d .s o ., m . b ., c h . m ., H o n g k o n g University-. The interest of the thymus gland is twofold. In the first place the stimulus given to preventive medicine in China by the Rockefeller Foundation has awakened the necessity for the study of medicine in China by the Chinese themselves. The teaching of anatomy and medicine makes use of textbooks which have been worked out by the stud}- of the European. The standards of morphological structure are European. It seems more than probable to me that we shall find that those standards are not strictly applicable to the Chinese race. It ma}^ turn out that the age standards are different; that the dates of ossification of the bones are later; that the general blood pressure is lower. If on the accumulation of knowledge such conditions are found to prevail it is clear that modifications will have to be made, not only in the teaching of medicine, but also in its practical application. In the second place the study of the thymus is interesting from the anthropological point of view. Races are distinguished b}' their more obvious characteristics, by the colour of the hair and its form, by the general appearance ; the anthropologist distinguishes differences m the skeleton, particularly the skull. Elliot Smith in his work on evolution has clearly demonstrated that more important than the skeleton is the brain. He has given clear indications that the brain of the Egj'ptian is of a different type from the European. I have strong evidence of a similar character that the brain of the Chinese differs also from that of the European. The work of Keith, Bolk, Stockard and others has drawn our attention to another group of organs— the endocrine or internal secretory organs. T hey suppose that racial differentiation is in some way brought about by the influence of the secretions of these organs. Sir Arthur Keith states that “ the theory which best explains all the facts is to suppose that Mongolian features arise under a peculiar or altered action of the growth mechanisms *A paper read before the H o n g k o n g and C h in a Branch of the B ritish M edical A sso ciation on A p r il 2nd, 1924. R ep rin ted from T he Caduçeus, M a y , 1924. The Thym us Gland in the Chinese. 647 centred in the thyroid gland.” The evidence can not be regarded as altogether satisfactory, for the arguments are based in great part on analogy. The features of certain diseases are so like the distinguishing features of certain races that Sir Arthur Keith has been led to believe that the causes of the features in those cases must be identical. In acromegal}- we get an increase of bone and muscle growth in certain places ; the hands become la rg e ; there may be a similar enlargement of the feet. But more important are the bony changes in the cranium and face. The cranium becomes increased in size, and in particular in relation to the function of mastication—■ an increase in the prominence of the temporal ridges, marked prominence of the supraorbital ridges, etc. In the face we find marked enlargement of the lower jaw and the masticatory apparatus in general. If we now look at the features of a gorilla we find that many of the characters of the acromegalic are normal to the gorilla. It certainly- appears that the possibility- of any individual becoming gorilla-iike is always present, but that some influence prevents it happening. Now an increased pituitary secretion over a pro longed period is the cause of acromegaly-, and without doubt the pituitary has an important influence on growth. It would appear that man has some mechanism which restrains this gland, and therefore Keith suggests that the influence of endocrine glands is important in racial differentiation. The race most closely- allied to the acromegalic is the Neanderthal race. The similarity between certain diseases of the thyroid and the features peculiar to the Mongolian has further caused Sir Arthur Keith to postulate that the Chinese race is differentiated under a thyroid influence. It would be more correct to say that the general appearance of any individual has been brought about by the combined influence of a great number of different factors, that his growth is capable of being influenced in particular by any or all of the ductless glands, and that the final result is possibly due to alteration in either the combining values of these glands or on the time at which they begin to act. It can be postulated that the onset of maturity is brought about mainly under the influence of the internal secretion of the sex organs, and that man’ s supremacy is due to a later onset of maturity than in other mammals, his yvhole life being retarded, as Bolk in particular has shown. 648 The China Medical Journal. Now, have we any evidence that the influence of the sex glands can be delayed in its action ? We have ; for, if the thymus gland is removed, the onset of sexual maturity is hastened; and vice versa, if the sex glands are removed the thymus gland fails to involute as early as normally. We also know that there is a close association between the sex glands and the thyroid. So that not only on the evidence of experimental physiolog}-, but also on the evidence of pathology, we have no doubt that the endocrine organs pla\- a very important part in the growth processes of the body. The action of these internal secretions is so much a combined process that it becomes a great difficulty to determine whether any particular phenomenon is the direct result of a particular gland, or whether the stimulation or suppression of that gland may not remove some factors which permit the uncontrolled action of the others. A s an example, there is no doubt whatever that the physical signs of acromegaly are the direct result of a change in the pituitary gland. But are the signs produced by the actual pituitary hormone, or are they produced by the combined action of other glands modified in their proportions by the deranged pituitary? Again, certain growth processes are intimateW associ ated with the thyroid gland. Are these due to the thyroid directly or are the oxidation processes of the bod3' so disturbed that once again the combined factors of all the growth processes become deranged ? We have made use of experiment and pathological conditions to help us in the answer, but to my knowledge there is no work which can tell us whether there are actual morphological differences between different races of men in the endocrine system. Bolk tells us that the sutures in the skull of man are later in joining up than they are in the anthropoid apes. He says that this must be due to the thymus. Such may be the case, but have we any evidence that the thymus gland is in any way different whether in function or structure ? During my investigations on other matters at the mortuary I was impressed by the fact that the thymus gland of the Chinese, as examined at the mortuary of Hongkong, was considerably larger than any I had previously seen, in spite of late age. The close association which has been shown to exist between the thymus and the thyroid led me to think that perhaps by an investigation The Thymus Gland in the Chinese. 649 of the thymus I might be able to throw light on the hypothesis put forward b}TKeith that the Mongolian characters arise under a peculiar or altered action of the growth mechanisms centred in the thyroid gland. The thymus gland is an organ which has a definite function to fulfil, and whatever that function may be it ceases to act with the same fulness after the onset of puberty, unless that function is taken over by some other organ. From an anthropological point of view its investigation in China is very important, as it may act as a basis for work on time relationships in the body. These time relationships are different in different species of animals. The length of intrauterine life in man is about nine months; in other mammals closely related it is shorter. Sim ilarly we have a lengthened period of childhood, adolescence, adult life and senility. These time relations are definite anthropological characters and quite conceivably have a marked influence on the ultimate structure of the race. This is a preliminary communication to a fuller investigation of the whole time relations in the Chinese. If these time relations arc different in the Chinese, then we must modify our medical teaching. T his paper can only be regarded as preliminary for another reason, and that is that it may have to be modified on the advent of further information regarding the age of Chinese. Unfortunately conditions are such that one cannot ascertain the age with certainty. The official form gives the name, age and address, which are obtained from the relatives. Apart from the fact that many- of the coolie class do not know their own age, complications arise in not knowing whether the age given is according to Chinese or British reckoning. Kvery effort has been made, however, to arrive at as close an approximation to the correct age as possible. Furthermore, even if the ages given are not strictly accurate, the findings are very significant. I have included with the description of the thymus the state of the hair development. At the present time an investigation is being made for the C .M .M .A . Conference of the state of the sexual development and hair development at known ages in the living, which should act as a useful check. The examination of the thymus was both microscopic and macroscopic. The microscopic condition has been classified into five types by Hammar. T h e China Medical Journal. 650 Type t . Infantile, with abundant parenchyma and moderate connective tissue. (Birth to 10 years-) Type 2- Juvenile, with parenchyma and connective tissue both abundant. ( 11 to 15 years.) Type 3. Young adult, parenchyma somewhat reduced, connective tissue abundant and the formation of fatty tissue going on. (16 to 20 years.) Ty*pe 4. Adult, with parenchyma more reduced, connective tissue more abundant and fatty tissue increasing in amount. (21 to 45.) Type 5. Adult. Mostly connective and fatty tissue, with strands of parenchyma. The macroscopic classification of the gland is more difficult. Hammar and others have taken the weight at different ages and found a gradual diminution in weight after the young adult stage. The weight is, however, difficult to use as a basis for comparison as to the amount of thymic tissue present. I have adopted an arbitrary classification, depending on the general size and bulkiness of the organ, into five groups, and have compared the microscopical appearance as far as possible. Group 1 . Gland abnormally large. Length from 6 to 8 inches, breadth from 2 to 3 inches. Full and lobulated. (Fig. 1.) Group 2. Gland large. Length from 5 to 6 inches, breadth from 2 to 3 inches; relatively bulky and lobulated. Group 3. Gland medium size. relatively bulky7. Length 4 to 5 inches and Group 4. Gland small, obviously lobulated, and thymic tissue of a reddish colour. Group 5. Gland insignificant in appearance. Obvious pathological conditions have been excluded. In the European the thymus gland in the adult is mostly a thoracic structure. It is cervico-thoracic'up to the third embryonic month, after which a fusion takes place with the pericardium; this fusion is said to cause an atrophic process to set in, in the cervical portion, the relation with the thy'roid being maintained by strands of connective tissue. In the Chinese the condition in d ifferen t; the The Thym us Gland in the Chinese, cervical portion of the gland is always well marked and is re presented by two well-marked lobulated upper extremities which reach, and in some cases pass under, the thyroid gland. The Fig. i —The thymus gl nd of a Chinese male, aged 2?, No. ?4 of the series. The protractor on the right i* the ordinary military protractor t " in length. The two superior lobes dissected out from uni'.r the thyroid gland are well shown. Fig. 2.— A drawing of the same case as Fig. i sketched at the time of post-moitem. microscopic examination shows that the regressive changes arc later here than elsewhere. The gland should therefore be classified in the Chinese as cervico-thoracic. I have drawn up a table to summarise the information so far gathered. It will be seen from this table that up to the age of twenty practically every gland is of large size. Figures 1 and 2 give a very good indication of the size of the glands placed in group 1 and regarded as abnormally large. The gland figured weighed 46 grammes after formalin fixation. It had a length of eight inches and a breadth of two and a half inches. There are in all eleven cases in the series classified in Group i , nine of which occur 652 T h e China Medical Journal. before the age of thirty, and two over that age at thirty-three and forty-three. Nine of them were subjected to microscopical examination and found to belong to either t\rpe 1 or 2 of H am m ar; thus it is clear that the large size is clearly associated with an abundance of thy*mic parenchyma. Glands which are included in Group 2 are slightly smaller than the above, and weigh from 35 to 40 grammes. It will be seen that glands of this size predominate up to the age of thirty, although many are found after this age, and in the particular group of cases which I have examined six are found between forty and fifty-. The glands in Group 3 would be regarded as large in the European, and it will be seen that they begin to appear at the age of twenty-five, and that after thirty-five the gland begins to get smaller in size. If we compare the size of the glands with their microscopic structure it will be seen that the large size is due to thymic tissue, for the abundance of parenchyma is held until a later age than in the European. Hammar's ages corresponding to his types are not in agreement with the findings in the Chinese. The young adult condition, instead of changing at 20, runs on till about 25 yrears of age. After thirty, regardless of the actual size of the gland, all the specimens are of the adult type. From these tables we can therefore assert that the thymus gland is later in undergoing its involution changes than it is in the European. We are now faced with the problem of determining whether the delay in thy mus involution is a normal physiological, and there fore anthropological, condition in the Chinese. The problem is not yet capable of a satisfactory answer; nevertheless, we can hypothesise, remembering that the function of an hypothesis is to build up further knowledge. It may fulfil its function and yet be found to be wrong; in yvhich case it is replaced by a further hypo thesis as a scaffolding for further advance. Taking firstly our known facts, the thymus is an organ which normally begins to undergo involution at puberty; it is in some way under the influence of both the sexual glands and the thyroid. Does the thymus give out a secretion which restrains the action of the sex glands, and therefore allows the sex glands to act by its involution ? T his would necessitate acceptance of the thymus within the group of endocrine organs, but it can by no means be considered as proved that the thymus gland gives off any internal secretion. Whatever The Thym us Gland in the Chinese. 653 its function, however,, it may be regarded as an organ belonging to the period of growth and development, and may therefore be taken as an index of maturity. One other question : Does its persistence so influence the thyroid as to cause this gland to exercise those influences of which Keith speaks? We do not know. The whole question is enlightened by the work of Bolk of Amsterdam. He says : “ I have advanced a ground to prove that the developmental rate of man has been retarded, a retardation which, by the way, is stronger in the male than in the female sex. To this retardation process he owes it, I would observe, that he is born nudus ei inerm is; that, in contradistinction to the other mammals, it is only rather a long time after his birth that his consciousness of self awakes, followed by the longer infantile, puerile, and juvenile phases.” The evidence of the thymus seems clearly to indicate that this retardation rate may be affected, not only as between man and the mammals, but between the. different races of man himself; and I would suggest that such differences in developmental rate are just as much anthropological characters for investigation as the size of the nose, etc. What evidence have we, besides the thymus gland, for making this hypothesis as far as the Chinese are con cerned? I have included the state of the hair development in the table, and it will be seen that the development of pubic hair can be considered to be retarded, an.l this may be regarded as the retarda tion of a secondary sexual character. From my present observa tions I am also of the opinion that the growth and development of the external organs of generation are later in reaching maturity. We are thus faced with the question as to whether our method of making racial comparisons has been correct. We have not sufficiently examined into the question of the time relationship. The stud}' of the skull is a study of an object in one unit of tim e; whereas the study of a race must include the whole period of its development. The problem of the anthropologist is very closely paralelled by that of the psychologist who attempts to analyse behaviour. Rivers tells us that “ the most important distinction which has been made between instinct and intelligence is that the former is innate and the latter acquired.” “ But when we endea vour to use the theoretical difference as a guide in practice and research, we are met by several difficulties.” The examination of behaviour from this standpoint is an examination of behaviour as a sequence of events rather than the examination of a single event in ¿54 T h e China Medical Journal. a unit of time. The advances in anthropology must be made along the same lines; for the race we must determine what are the characters which are innate in the race, and what are those qualities which have been acquired in the individual. The distinction between the acromegalic and Neanderthal man is that the characters of the one are acquired ; of the other, innate. Whilst it may be that the pituitary gland is the causative agent in both cases, the problem which has to be answered in the case of the Neanderthal is how the germ plasm becomes modified so that a pituitary influence becomes inherited. The condition in which the thymus gland is found in the Chinese must be regarded as innate unless we can show that each individual is subjected to environmental conditions causing its persistence to be acquired. The persistent thymus is an expression of reLarded development and is only a part of the general retardation. K eith’s hypothesis might possibly be modified b\T stating that, whereas the cause of the racial differentiation of the Chinese is not known, its results are expressed in a general retardation process which permits the hormones of the thyroid to exercise a fuller influence on the race. This of course assumes that the thymus retardation is an index of some altered condition of the thyroid; and of this there is some evidence. We may say of structure what John Hunter says of function : “ A s every naturai action of the body depends, for its perfection, on a number of circumstances, we are led to conclude that all the various combin ing actions are established while the body is in health and well disposed; but this does not take place in diseased conditions, for disease, on the contrary, consists in the want of this very com bination.” If we are to assume, therefore, an endocrine influence in racial differentiation, we must regard the thymus persistence as a part of the difference in the time relationship of the combining factors, not necessarily the cause. This difference of combining factors expresses itself in those slight differences of features which go to distinguish races. The differences, not apparent at first on account of the great variety of minor cjifferences in the race itself, become more apparent when viewed as a whole. Is it possible for us to give any indication of why it is that the thymus gland is retained ? I will try to give an indication of the possibility of an answer; the proof of which it should be The Thym us Gland in the Chinese. 655 possible to work out by a careful study of Chinese customs. It is more than possible that selection has played a part in the racial differentiation of the Chinese. If selection is of such importance in determining the types of domesticated animals, it should play some part in the differentiation of man. The marriage customs of the Chinese are, I think, ancient and conservative. These customs have for their basis that the selection of the contracting parties is parental. In the very nature of things the parental choice will be such that, other things being equal, the contracting parties are as near to the ideals laid down by social convention as possible. The Chinese admire the placid type— the type which is expressionless, and not given to the outward display of fear, anger, and the emotions in general. The anthropological type might almost be regarded from European standards as a child-like type; the Chinese countenance with its hairlessness, smooth forehead, wide interocular distance, etc., is child-like. Taking the European as a standard they seem to have been retarded. And if so, according to the observations of Bolk, should be looked upon as very high in evolutionary advance. It is conceivable, then, that the choice would fall on those who gave the appearance of being late in arriving at m aturity; and who might, therefore, have a persistence of the thymus as one of the expressions of that immaturity, perhaps even the cause thereof. If such is the case the presence of the persistent thymus is due to some change in the germ plasm transmitting influences which cause a retardation of that orderly sequence 01 events going to make up the adult characteristics of the race. The possibility of the persistent thymus being of an acquired nature must not be overlooked. It has been suggested that the thymus has some function concerned with the production of immunity from disease. Hammar has avoided any cases which show evidence of disease in his work on the thymus of the European, knowing that it is subject to change in infectious conditions. Diseases of all kinds, and in particular infectious and parasitical diseases, are so common in China that it is next to impossible to obtain data from normal people; and it is possible that malaria and other conditions may have, to be seriously considered. If we had data from other infected countries as to the state of the thymus a definite answer might be given to this aspect of the problem; at present it is not possible.

Figure i is a low power view of the tumour in the less changed part. Even here, in the upper part of the micro-photograph, there is a mare or less circular patch of hyaline degeneration. The cells of the Lumour are spindle cells for the most p art; multinuclear cells are present. There is hyaline change in the protoplasm of the cells, with loss of nuclei. Figure 2 shows multiple areas of degeneration. These are roughly circular or oval in shape. The rim and the central part of these areas of degeneration show different staining reactions, the rim staining intensely with haemotoxylin and the central area with acid fuchsin. Sometimes the central part is streaky in appearance or actually absent, leaving an empty- space. Figures 3 and 4 show a still further stage. The tissue here is acellular and numbers of empty spaces are present, occupying the places of the areas of degeneration (Fig. 2). These areas have evidently become liquified and absorbed. With Van Gieson’s stain the lining wall of the spaces takes the acid picric stain while the inter-cystic areas take either the acid fuchsin or the picric stain. Anything more unlike a sarcoma than Figures 3 and 4 delineate, it is difficult to imagine. Case 2 . — L arge S arco m a of th e S capu lar R e g io n . This tumour occupied the whole of the upper part of the left side of the back, being of very considerable size. It occurred in a man of fifty years of age. A t operation it was apparently encapsuled. Before the tumour was removed some difficulty was experienced in diagnosis, because in several places the tumour was so soft that fluctuation was elicited. The tumour seems to belong to the variety of sarcoma that grows from tendons and aponeuroses, and is usually found in the hand or foot, although some of the features said to belong to this type of tumour are not evident. At any rate, it is a form of giant-celled tumour. Fig. I.— Periosteal sarcoma: circular patch of hyaline degeneration. Fig. 2 — Periosteal sarcoma : multiple areas of degeneration.

During the previous twelve years half a dozen follicular odontomes of the superior maxilla had passed through his hands. These all had one common charac teristic; onh' the anterior wall of the bone' c}\st bulged (i.e., forwards); there was no bulging of the other walls; this wall was thin and could easily be pushed backwards by pressure within the lip above the line of the teeth. The picture presented by this tumour, taken from an eighteenyear-old girl, was typically that of a sarcoma of the superior maxilla growing from within the bone. The left cheek bulged greatly forwards, the nose was pushed toward the right, the eye was pushed upwards and the palate downwards. The anterior wall could not be pushed back b\* the finger. The superior maxilla was removed The photograph ( F ig .8) shows through a window afterwards made in the wall of the bone cyst,, the unerupted tooth, T ; also a considerable amount of bony degeneration in the floor of the c y st; M points to a molar tooth.

The patient had bilateral syphilitic epididy-mitis with almost complete obliteration of vessels of the spermatic cord (Fig. 9), and complicated on one side by a large inguinal hernia.

His diet was the usual one in North China, consisting mainly of millet. At the age of sixteen years patient had pain in his right leg, due, he said, to a chill; tor eight days it felt numb and was a useless member. -He could-not put it down... At the age of 25-26 both his legs felt cold, and this in spite of warm clothes. This condition was progressive and was felt whether standing or walking. After lialf-an-hour’s walking he was obliged to rest on the k ’ang (warm brick bed) for four or five hours before the circulation was restored. Each night on going to bed he was conscious of cold lim bs; after the lapse of time they warmed up. He stated that in summer time things seemed all right. He also stated that there was 110 sweating below his knees. During the past year, 011 going to his shop door to open it he had to stand before returning, because of his inability to use his legs; this was due to cramps in the calves of his legs, and in the soles of his feet. Sitting down and rubbing his limbs restored their function. Patient came to hospital with commencing gangrene in the tues of the right foot. Even in the femoral artery of the right leg 110 pulsation could be detected. T he Sachs-Georgi test was negative. Amputation of the right limb half-way between the knee and ankle was perform ed; healing was protracted. Figures 10 and 1 1 show the condition of the posterior and an terior tibial a r t e r i e s below the level through which amputation was carried out. The anterior tibial artery not only showed marked endarteritis but also a thrombus within the vessel, and the vein showed endophlebitis.

The' following case is reported because of the unusual distension of the bladder following retroflexion of a gravid uterus. This .is the second case of this condition seen by the writer during ten years in China. Probably- there are many similar cases here which do not come to the practitioners of foreign medicine. According to De Lee, “ it is usual that in retroflexion the uterus is displaced before the pregnancy'. Unless the displacement is complicated by adhesions, no symptoms are complained of until the uterus begins to draw on the neck of the bladder. Sometimes there is a sensation of fulness in the pelvis, with bearing down pains, or pains radiating from the sacral or lumbar plexuses. At the end of the third month bladder symptoms appear— frequent desire to urinate, great pain, and the necessity to strain to pass water, the feeling that the viscus has not been emptied, and then coming on 'more suddenly^, retention of urine.” Two cases are mentioned by^ the same author in which the bladder contained 2,880 c.c. and 8,000 c.c. of urine respectively. : R e p o r t of C ase.

Norman White, to go to the F'ar East and collect information regarding the incidence of epidemic diseases, especially those of international importance, in important ports, and the measures taken to prevent the transmission of these diseases to other ports. During a tour that lasted over nine months, Dr. White visited most of the principal cities of the Orient and made careful investigations. As the result he was able to present a voluminous and very valuabie report to his Committee. Of special interest to practitioners in China, wherever plague is endemic or epidemic, is the part of the report dealing with this disease in its different forms. B u b o n ic P lague and D P n e u m o n ic is e a s e s P lague S eparate ? The epidemiology, etiology, symptoms and so forth of bubonic plague and pneumonic plague are compared and contrasted, and the conclusion is reached that there is justification for considering them as two separate and distinct diseases; that certainly from an epidemiological view they are as different as any two diseases well can be. Dr. White admits that no real difference has ever been demonstrated between plague bacilli isolated from patients suffering from primary pneumonic plague and the bacilli isolated from patients suffering from bubonic plague. Nevertheless, a prolonged and careful study of all the available epidemiological data, only a fraction of which is referred to in the report, has driven Dr. White to the conclusion that the plague bacillus alone does not, and cannot, cause widespread epidemics of pneumonic plague. It seems more than probable that there is an additional organism at work; in other words, the plague bacillus is in symbiosis with another pernicious organism when pneumonic plague is caused, 664 The China. Medical Journal. " . which is thus a disease sui generis. The continuation, or refuta tion, of this theory must pend further laboratory investigation, opportunities for which may be afforded by the next outbreak of primary- pneumonic plague. If the existence of this hypothetical organism be postulated— an organism nonpathogenic for rodents— all', or nearly^ all, that has been written regarding the history- and epidemiology- of plague that is obscure 111 the light of present knowledge becomes clear. In k e c t iv it y of H um an B u b o n ic P la g u e ? In support of his argument Dr White urges that bubonic plague is essentially a disease of rats, and that all available evidence goes to show that human bubonic plague patients are not infective except in very exceptional circumstances. Plague hospitals in British India, and in other parts of the Hast in which epidemics of bubonic plague occur, are almost completely* free from danger to doctor and nurse in spite of the fact that the precautions taken to avoid infec tion are nil compared with the elaborate precautions that are absolutely essential during pneumonic plague epidemics of the north. Further evidence of the lack of infectivity- of human bubonic plague patients is afforded by the fact that approximately 75 per cent of cases of bubonic plague are single cases, that is to sayT, one case per house. When multiple cases occur, it is the rule for them to fall ill more or less simultaneously. Exceptional cases of personal infection do occur, which is not surprising when one remembers that in fatal cases of bubonic piague there mayr be term inal pneumonias in which the patients may- expectorate sputa containing vast numbers of virulent plague bacilli, but the exceptions are relatively unimportant and do not upset the main argument. Xone of the outbreaks of bubonic plague gives rise to an epidemic of pneumonic plague. Furthermore, the term “ septicaemic,” which has given rise to much confusion, should be discarded. The difference between bubonic and septicaemic cases is one of degree, not of kind, for the vast majority' of plague cases have plague bacilli in their blood at some period of the disea.se. The term “ septicaemic” should therefore be rigidly confined to the description of a clinical condition, and its use excluded from writings on the epidemiology of the' disease. Bubonic and Pneumonic Plague . T he Im po rtan ce of S C h a in pread and of P the G lagu e r a in T 665 rade in the . Whether the distinction advocated between bubonic plague and pneumonic plague be accepted or net, it is claimed that at any rate from the point of view of sanitary conventions and prophylactic procedure, bubonic plague and pneumonic plague should be regarded as different diseases. If this is done, plague prevention cari be rendered less irksome and more effective than it is at present, and it will be possible to concentrate on probabilities and essentials and to neglect mere possibilities. As Dr. White has often done before, he insists on the importance of grain and the grain trade in the spread of plague. He gives some examples of the association of plague with rice importation, and affirms that if it were possible to break the association of rats and grain the control of plague in the Far East would be readily assured. “ In the East, as elsewhere, rats are much more numerous in grain stores and markets than they are in oilier places. It is for this reason that grain stores and markets afford special facilities for plague infection surviving the adverse climatic and other conditions of the non-epidemic season. During the height of the epizootic, which incidently synchronises in many parts of the East with the harvest, a time of the year when the movements of grain are especially active, the dangers attendant upon the transference of such merchandise from an infected to a plague-free locality’ are obvious. Consignments of grain afford opportunities for the transport of rats and rat-fleas unsurpassed by those afforded by the movements of any other form of merchandise, and they are placed in the most rat-infested parts of the town of arrival.” The sanitary and other measures that should be taken from this point of view to prevent the spread of plague are described. S um m ary of C o n c l u s io n s. The report is summarised by Dr. White in thirty-one con clusions, some of which are as follows : 1. Bubonic piague is, all things considered, the most im portant ship-borne' disease in the Orient. 2. Bubonic plague is essentially a disease of rats, arid the human case is, for all practical purposes, not infectious. 666 The China Medical Journal. 3 . T h er e is a b u n d an t ep id em io lo g ica l in fo r m a tio n , based on a quarter of a c e n tu r y ’s e x p er ie n c e, to j u s tify th e co n sid era tio n o f bubonic p la g u e and p n eu m on ic p la g u e as tw o e n tir e ly sep a ra te and d istin c t ep id em ic d isea ses. 4. It is extremely doubtful whether the plague bacillis alone can give rise to pneumonic plague epidemics. 5. Epidemiological facts indicate the probability that pneu monic plague epidemics are caused by the plague bacillus in symbiosis w7ith another organism. 6. It is probable that this “ hypothetical'’ organism will be found to be non-pathogenic for rodents. 11. The control of the grain trade and the proper storage of grain are almost synonymous w7ith efficient plague preventive measures. 13 . If due consideration be given to the attributes of the rat, it is possible to erect storehouses that can be kept automatically rat-free. Many “ rat-proof” stores now in existence harbour a large rat population. 17. Further work is required to devise more satisfactory methods of fumigation than those at present in use. 18. The disinfestation before shipment of rat-favoured mer chandise from plague-infected localities demands much, more consideration than it. receives. Such measures should, wherever possible, be taken at the port of departure. 20. The history of the spread of plague in the East indicates that attention paid to the usual channels of infection could secure almost absolute immunity from plague, and that without vexatious restrictions to the free flow of commerce. 21. The tendency of the disease to die .out in large areas of the East, unless reinforced by repeated introduction of infection, accentuates the importance of preventing such re-infection. 25. British India is by far the most important reservoir of plague infection in the East. Java comes second. The prevalence of the disease in British India is decreasing, noticeably in those provinces that have suffered most. 29. In most Oriental towns, anti-plague measures are unsuc cessful, largely on account of the antagonism of the population to such measures. Bubonic and Pneumonic Plague. 667 30. 'The disinfection of houses and their contents is the most commonly practised of all anti-plague measures; it excites great antagonism and, as carried out, is of extremely doubtful utility. 3 1. Suggestions are made regarding a new orientation of plague policy in many Oriental towns. When the report was presented by Dr. W'hite to the League of Nations Health Committee, his hypothesis that pneumonic plague and bubonic plague are two distinct kinds of plague and that in the former there is a symbiosis of causal germs, was considered very* cautiously, one expert saydng that “ symbiosis had never yet been observed, and was a mere hypothesis not based on any concrete facts.” After much discussion a Sub-Committee was appointed to consider the whole question. Its report, of which the following is a part, was adopted as an Annex to the main report. “ As the author [Dr. White] candidly admits, it is impossible to discuss here the very ingenious theory regarding pneumonic plague, [that it is] a disease totally distinct from bubonic plague. Only experiments and laboratory research will make it possible to solve this question and to determine the part played by symbiosis between the various organisms. “ Although it would not be wise at the present stage of scientific research to draw prophylactic conclusions from this theory- regarding pneumonic plague, certain facts are recorded in Dr. Norman White’s report which the Sub-Committee unanimously accepts. “ There is no doubt that too great an importance has been assigned to man in the propagation of plague. Not that man is incapable of directly transmitting this disease. We know cases— rare, but conclusive—of bubonic plague being transmitted from man to man, but only-' in eminently ecto-parasitic surroundings. “ The pandemic form of pneumonic plague appears to be localised in the North-east of China and Siberia, and, up to the present, conditions in the southern regions of the Far East and of Europe do not appear to have been favourable to its extension; subject to due reservations, therefore, pneumonic plague may be c o n s i d e r e d as relatively unimportant, in so far as the framing of regulations for maritime traffic is concerned. 66S The China Medical Journal. “ Pneumonic plague, as met with in Europe, in North Africa and in America, has never formed anything but small foci centres which were easily* stamped out. “ Despite these considerations, we must not, however, exclude the possibility* óf danger from this disease ; the variations in what the ancients called the epidemic spirit are well enough known, as also its manifestations, which differ so greatly according to place, times and conditions, which as yet are unknown. “ From the practical point of view, we may consider it as established that human plague is in all cases a concomitant of epi zootia plague. It is, therefore, the rat and not man which represents the danger against which measures must primarily be taken. “ If it is the case that certain ports, as, for instance, Manila, Shanghai, and the Formosan ports, have succeeded in totallyeradicating plague, the Sub-Committee is anxious that the attention of the Governments interested in this question should be drawn to these facts and that they should be informed of the measures which made it possible to achieve this remarkable result. “ All observations made by epidemiologists in the East, as well as in Europe, show that epizootic plague is in any^ case tending to disappear; only reinfection keeps it alive, and il is of the greatest importance that such reinfection should be prevented. “ It is essential that all vessels and goods coming from infected ports should be protected from rats before embarkation ; that such vessels should be cleared of rats before their departure, and that goods liable to carry* infection should be isolated under conditions such as those laid down by* Dr. Norman W hite.” The following resolution was also adopted : “ The Health Committee recommends the creation, in a Far Eastern port to be chosen by* agreement between the Governments concerned, of a Bureau which would represent, for that portion of the globe, an extension of the Epidemiological Intelligence Service of the Health Section of the League of Nations. The Rockefeller Foundation might be asked to lend its assistance in the organisation of this bureau. The Committee points out that the Far Eastern Association of Tropical Medicine has unanimously recognised the utility* of such a bureau.” Hongkong Medical Conference., 1925- 669 HONGKONG MEDICAL CONFERENCE, 1925.

Publishers : Tientsin Press, Limited, Tientsin. 1924 Fortunately there has been no epidemic recently of pneumonic plague in the north of China, so the report consists mainly of a review of work done in the past. It contains an interesting history of plague epidemics in all countries from the earliest times, so far as these have been recorded. This is followed by a chapter on “ Plague in Wild Rodents, including latest investigations into the role played bjT the Tarabagan,” in which it is proved that the tarabagan can be the source of plague in man, but the exact mode of transmission is still undetermined. The next paper on “ A Study of the Morbid Histology^ of the 1921 Manchurian Plague Epidemic,” appears elsewhere in abridged form in this number of the “ China Medical Journal.” Two other papers on plague are entitled “ Notes on the Histological Lesions found in Organs of Naturally Plague-infected Tarabagans” and “ The Original Home of Plague.” Then follow “ Remarks on the Incidence of Certain Diseases in Chinese and Europeans,” and other papers on miscel laneous subjects. The report is well illustrated, some of the pictures being colored. HAN G C H O W , C H EK IA N G . L o v e i n A c t i o n '. Report of the Universal Benevolent Healing Office in Heaven Below. Being the Annual Report of 1923 of the Medical Reports. 671 Hangchow Hospital and Medical Training College in connection with the Church Missionary Society.

Departments of work in the city, 13 ; departments of work outside the city, 14. This is the report of' a large Institution with many Departments. The work and the report are alike unique, and difficult to summarise. The first article is a general review, which passes from the particular activities of the Hangchow Hospital to the aims and methods of medical missions in general; then follow comments on the value of medical education ; on opium smoking; spiritual healing; work among out-patients; venereal disease and the social e v il; the work of the Leper Hospital; the treatment of leprosy with the ethyl esters of chaulmoogra o il; reports by Dr Sturton and Dr. Chen on the medical and surgical work; by Miss Curtis, as head of the Nursing Department in the Men’s Hospital and of the Maternity Section; by Miss Weathereil, of the Women's Hospital; by Mrs Main, on the needs of the various departments, and acknowledging help received. There is also a report of the evangelistic work, the reprint of a circular letter sent out by?- Mrs. Main, and a graphic account of the experiences of Dr. and Mrs. Main, who were staying at Miyanoshita at the time of the terrible earthquake in Japan last year. Total number of in-patients during the year, 3 ,14 5 ; out patients, 35,25 3; lepers, 74; patients with tuberculosis, 204; opium-smokers, 47 ; cases of attempted suicide, 138 ; accident cases, 3 2 3 ; operations, 843; pathological specimens examined, 2,784; maternity cases, 334 in hospital and 31 outside. A number of students are studying medicine, and sixteen girl students are studying midwifery-. Financial statement : income, $85,749,20 : expenditure, $83,045.93. The object of all these manifold activities is well stated in the report : “ If crowds of out-patients, full wards, brilliant operations, diseases cured, precious lives saved, lepers cleansed, consumptives relieved, students taught, chemists graduated, old buildings Renewed, new hospitals and homes built, the new college building going on well, lame ducks helped, the gospel preached, tracts and 672 The China Medical Journal. scripture portions distributed, happy fellowship, loyal workers, many friends, just debts paid, together with many other blessings received, were our end and aim, then might we cry ‘ Eureka’ arid rest on oyir o^irs. But these things do not constitute the chief end of our work. We are out through every department of ours to win souls for Christ, to work through men's bodies to their hearts,’to restore men from sickness to health, and to lead them from darkness into light.” CANTON: KUNG Y E E M E D IC A L COLLEGE A N D H O SP IT A L A N D T R A IN IN G SCHOOL FOR N U R S E S . R E P O R T FOR 1922-1923. Faculty of Medical School : 7 foreign and 23 Chinese medical instructors. Hospital Staff : 3 foreign physicians and 13 Chinese physicians. Nursing Staff: Mrs. M. S. Todd, R .N ., Superintendent; S .Y .A u , R .N ., Assistant Superintendent; nine graduate nurses. The object of the Kung Yee Medical College is to give a thorough medical education to promising young men and women who desireljto enter the medical profession. Connected with the; school is a modern hospital, where real scientific work is done and where the students receive their practical training. The Society was first organised in 1909. At the present time it has 140 mow of land (25 acres), two hospitals, one out-patient or free clinic building, the main College building with six laboratories, two lecture rooms, a library, an Assembly hall, three office rooms, a faculty room, a book room, a waiting room and a large lobby; an anatomy building with a large dissecting room, a lecture room, a laboratory and an office; one dormitory^ accommodating 120 medical students; four modern^ bungalows for staff residences; and a temporary Nurses Home, which will accommodate 24. These build-r ings are all well furnished and the laboratories are fairly well equipped. The policy of the staff is to meet tlie standard set by the American College of Surgeons for the recognition of hospitals. In 1923 the Medical College was organised as a university, as the Government of China permits one department, such as medicine, agriculture, or law, to take the name of a university if it is able to meet the standard required by the Government. Therefore the name of the institution has now been changed to the Kwong Tung Kung Yee University Medical School and Hospital. Total number Medical Reports. 673. of students enrolled during tlie year, 16 4 ; students graduated during the year, 13 . Total number of graduates since the school was opened, 234. The work of the hospital staff during 1923 was the hardest it has so far experienced, which was partly owing to the arrival of numerous wounded soldiers following the fighting which took place near Canton between the Kwangsi and Yunnan forces. From the beginning of April to the end of the year there was a daily average of about 400 in-patients. The Government was unable to pay in hard cash for the cost of taking care of the soldiers, so it settled part of its bill byr giving the institution seven acres of land. The total number of m-patients during the year 1923 was 4,788, with 121,0 56 hospital days, as against 3,440 in-patients with 47,560 hospital days in 1922. Total receipts, $18 0 ,0 9 1.0 5 ; total expenditure, $178 ,552.6 5. R O C K E F E L L E R F O U N D A T IO N . R E P O R T FOR 1923. During the year 1923, the International Health Board, the China Medical Board, and the Division of Medical Education of the Rockefeller Foundation supplied fellowship funds for 636 individuals in 29 different countries; supported through the League of Nations interchange institutes for 54 public health officers from 27 nations; arranged international visits of one commission and of 24 visiting professors; furnished emergency relief in the form of medical literature or laboratory equipment and supplies to' institutions in 15 European countries; sent scientific material to Japan after the earthquake and invited a group of Japanese medical scientists to use the laboratories of the Peking Union Medical College as guests of the institution; continued to contribute to schools or institutes of hygiene at Harvard, London, Prague, Warsaw, and Sao Paulo, Brazil; co-operated in nurse-training at Yale University and in France, Belgium, Brazil, China and the Philippines. It accepted an invitation from Brazil to participate in a com prehensive attack upon yellow fever; had a share in demonstrations of malaria control in 12 American States, and conducted malaria surveys or studies in the Unjted States, Brazil, Australia, Nicaragua, Porto Rico, Salvador, the Philippine Islands and Palestine; either continued or began anti-hookworm work in conjunction with 20 governments in various parts of the world; contributed to 183 674 The China Medical Journal. county health organizations in the United States, New Brunswick (Canada), and Brazil; continued a study of the medical schools of the world by visits to Belgium, Austria, Czechoslovakia, Germany, Hungary, Poland, Turkey, Hongkong, the Straits Settlements, Siam, Canada, England, Scotland, Wales, the Netherlands, Mexico and Colombia. It offered to contribute £280,750 to the development of medical education in certain universities in the British Isle s; gave $500,000 to the University’ of Alberta, and pledged $250,000 to the University of Pennsylvania toward buildings for anatomy' and physiological chemistry ; continued to support a modern medical school and teaching hospital in Peking; aided two other medical schools and 25 hospitals in China; assisted premedical education in several institutions in China and agreed^to do this also in Bangkok, Siam ; lent representatives to governments and institutions for various types of counsel and service; continued to support a disease reporting service of the Health Section of the League of Nations; contributed to mental hygiene projects, demonstrations in dispensary administration, organization of dispensary work in France, and to other undertakings in the fields of public health and medical education. STATUS OF THE MEDICAL PROFESSION IN CHINA K . Chim in W ang L .M .S .H ., S h a n g h a i-H a n g c h o w R a ilw a y , H angchow . The well-known author, R . L . Stevenson, for years under the constant care of physicians, expressed the conviction that “ the doctor is the flower of our civilization—such as it is—and partakes more of its virtues and less of its defects than any other class of m en.” Can the same be said of Chinese medical practitioners? In other words, what is the status of the medical profession in China? Some Chinese writers speak well of doctors. Chia Y i, of the Han dynasty, remarked that the “ superior m an” , if disinclined for official life, will practice medicine for the reason that a doctor also can serve the people. Cheng Ym-chuan thought that the The Medical Profession in China. 675 scholar who serves his parents should not be ignorant of medicine. L u Chi, a prime minister of the Tang dynasty, compared the merits of a good doctor with that of a good premier, which made Fan YVen-ching of the Sung dy’nast}’, utter the famous saying that if he could not become a good statesman he would be a good doctor. Medicine itself is spoken of as a benevolent art, and physicians are styled “ kou sh ou ” ( ® ^ ) or “ healers of nations,” who have the great responsibility of “ controlling life and death.” In spite of these high tributes, however, members of the profession have never been accorded any position in society. Con fucius said ironically that without perseverance one cannot even become a priest-doctor. The Sea and H ill Classic (Oj m m ) states that east of Kai Min there lived certain sorcerers named Pan, Ti, Yang, L i, Fan and Shang, who were all skillful physicians. According to the Shou Wen (fgj .3 0 , the sorcerer Pan was the first doctor. Thus religion and astrology merged into healing, and, as in all early civilizations, the first physician was a priest and the first priest a physician. It was not until the Chow dynasty that the functions of these two professions were separated. The book entitled Chow Rituals (M i i > records that the chief sorcerer shall direct the junior sorcerers to make offerings m times oi. drought, and that the doctor shall superintend all matters relating to medicine and shall collect drugs for medical purposes. An interesting sidelight on the art of medicine is found in the formation and development of the ancient Chinese character for doctor (H). It is composed of three parts. At the top on the left corner is a quiver (£§} ; oh the right corner a spear ( £ ) ; below is the symbol for sorcerer or priest (3$), the whole character meaning that the priest employs strong weapons to kill or expel the demons of disease. Later, the third part of the s\7mbol was changed to wine ( I f ) , signifying that the practice of medicine was no longer confined to the priests but had been taken up by doctors who administered elixirs or wines to their patients. In later tunes, though doctors were a distinct class from priests, their social standing was still not much raised, for we learn from L u ’ s Spring and Autumn (& J£ ^ $ C) that medical practitioners were held in low esteem by the people, as “ they employed poisonous drugs to treat and expel disease, hence the ancients despised them The China Medical Journal. and assigned jthem a low position in society.” Because of this social inferiority, Hua To, the celebrated surgeon, felt ashamed of bis profession and wanted to retire from it. During the Han dynasty and the two following dynasties, superstition reached the highest point. A new form of treatment was invented by Chang Tao-ling, a Taoist priest, who made use of charms and incantations for the curing of diseases. His followers were called “ robbers-of-five-piculs-of-rice,” as they usually exacted this quantity of rice for their services. Seeing the lucrative income brought in by these devices, Buddhist monks soon invented their own system of charms. The result was that the market was flooded with the wares and remedies of both schools, and it was claimed they had the power of conferring every benefit under the sun. The search for the philosopher’ s stone and the elixir of life was also most popular at this time. Magicians, doctors, and alchemists were found everywhere experimenting with herbs and minerals in an attempt to discover an elixir which would confer on the person drinking it everlasting life and beauty. Of the twentytwo rulers of the Tang dynasty- seven experimented with these elixirs and died from their effects. Such were the prevailing conditions. It is no wonder that the Tang Annals said that “ mathematicians, surveyors, fortune tellers, physiognomists, physicians and magicians were charlatans. The sages did not regard them as educated.” The culminating blow to the old Chinese medical profession was when Szu Ma-chien, the Herodotus of China, classified doctors on the same footing with fortune-tellers, astrologers and palmists. Since then educated people have disdained the practice of medicine as a regular profession. Hence Chu Hsi, the famous commentator on the Confucian classics, indicated the social position of physicians in the following words : “ Sun Szu-mo was a noted doctor of literature of the Tang dynasty, but as he practised healing as a profession he was relegated to the class of artisans. What a pity- ! ” The general distrust of the doctor’s ability and character mayr be further shown by the following quotations and proverbs. “ Doctors cannot cure their own complaints4’ (Huai Nan-tzu, •=p). “ The son of the good sorcerer is generally killed by demons.” “ The son of the great doctor usually dies of disease” The Medical Profession m China. 677 (Ancient Essay ^ $C). “ It is a middling course to leave a disease untreated” (Annals of Art and Literature, ‘ " t o take lio medicine is the best cure” (Proverb). “ Medicine does not kill, the physician k ills ” (Proverb). “ Do not take medicine compounded by a doctor who is not backed by the experience of three generations” (Record of Rites, jjjf[ fS). “ Quack doctors kill people ” (Proverb). “ What the doctor says is all right, but what he sells is false” (Proverb). “ Doctors puncture and plaster and use spurious drugs” (Proverb). On account of the low estimate of the value of their services doctors often play a very secondary role in the treatment of a case. Their prescriptions are viewed with suspicion, carefully examined, discussed and analysed as to whether the medicine is “ cooling” or “ heating” , suitable or unsuitable to the patient. If, in the opinion of the patient’s relatives or friends, the medicine prescribed is not perfect, they will add, alter, remove some of the drugs mentioned, or entirely reject it. Physicians are called or dismissed at w ill; two or three or even a dozen may^ be engaged at the same time. Only rarely is this for the purpose of consultation. The physicians come one after the other, each writes a prescription, explains the supposed cause of the illness, and his duty is done. The richer the family, the more numerous the doctors engaged ; the larger the household, the greater the fuss. It is not an uncommon sight to find half a dozen doctors all waiting in the house for their turn to examine the sick person. When each has written his prescription the relatives and friends will hold a consultation and “ pass sentence” on the relative merits or defects of all the prescriptions, and then one will be sent to the druggist for dispensing. The unfavourable attitude adopted by the people, especially by the educated class, towards medicint in general has been brought about by many causes. Instead of being regarded as a learned science and art, the practice of medicine has been, and still is, considered as an avocation, a side occupation, or else it is regarded as pure business. There are no proper schools to prepare a medical student for his work. Any one can set up as a doctor. A coolie who inherits a few prescriptions from his ancestors, or an old woman who has had some experience from rearing her children, will put up his or her sign-board and start practice. Going a little The China Medical Journal. higher we find a class of men who are too lazy or too weak for manual labour, or not educated sufficiently for literary work, who study for a few months some old medical books and then take to medicine to earn the means of livelihood. In the higher grades of practice an apprenticeship is served either under an old doctor, or in a druggist shop, to enable the beginner to pick up some knowledge of medicine before he commences practice. The following poem, entitled “ Lamenting the Practitioner'* (IT •§! HP» by Hsu Ling-tai, a famous and versatile doctor of the Kien-lung period, describes the standing of Chinese physicians in a most thorough manner. We give a prose translation. “ Having nothing to do they took to healing. W hat do such people know about the value of human life ? Or that saving people is not a business proposition? They onty read half a medical book and learn the uses of a few drugs. Before starting practice they just inquire what medicine the popular quacks are using and then try it on their patients. If some good results happen they are themselves surprised ; if death occurs they will say that the medicine is good but the disease is fatal. How many innocent boys and girls, young husbands and wives, aged fathers and mothers, have you killed? And people do not blame you, but on the contrary compensate you for the attendance and medicine! Oh, how could you have the heart to do it ? Though the law cannot reach you, yet heaven will not be deceived. Should you really want to serve suffering humanity you must first read more. If unable to do so, better change your profession so as to escape the fires of hell ! ” T he C h in e s e S i c k - r o o m . —Nothing in the habits of the Chinese presents a greater contrast to those of Westerners, than the behaviour of the Chinese to one another in cases of sickness. The notification of the event is a signal for all varieties of raids upon the patient, from every quarter, in numbers proportioned to the gravity of the disease. Quiet is not for a moment to be thought of and strange to say no one appears to desire it. The bustl attendant upon the arrival and departure of so many guests, th work of entertaining them, the wailings of those who fear that death is soon to take place, and especially’ the pandemonium mad by priests, priestesses, and others, to drive away the malignant spirits, constitute an environment from which death would be to most Europeans a happy escape.— Arthur Smith, Chinese Characteris tics. Medical Ethics in China 679 MEDICAL ETHICS IN CHINA.* E d w a r d M. M e r r in s , m.d., S t. J o h n ’s U n iv e r s ity , S h a n g h a i. The purpose of this paper is not to discuss abstract moral questions concerning human motives and conduct remote from the practical affairs of the medical profession, nor to discuss questions of casuistry interesting onljr to logicians and theologians. Its object is to consider the ways and means by which we can help our Chinese friends to give to the medical profession now being formed in China the same high dignity and honor that the profession has in the West. This is a task of peculiar difficulty. China is a country of advanced and ancient civilization, but the state of medicine has always been very7 backward. Laws and regulations governing the practice of medicine are unknown. Anyone is at liberty to proclaim himself a doctor, even an ignorant coolie on the street. Generally, the native doctor possesses a lew prescriptions, perhaps heir-looms, some of which are of considerable value if reports be true, and these constitute his whole armamentarium. Among the people at large there is no conception of medicine as a science. All diseases are ascribed to the agency7 of supernatural beings or to unknown supernatural causes, hence the temple priest with his charms and incantations is visited equally with the doctor. In such an environ ment our young scientifically-trained Chinese doctors, not very numerous, are obliged to follow their calling. They are between the horns of a dilemma. If they do not fall into the ways of their counti'ymen, it will be very slow and difficult to build up a lucrative practice ; if they d^> fall into such ways it is hard to see how a- high ethical standard can be established and maintained. Further, when a doctor is called in and prescribes, if there is no immediate improvement, even though the case is one of typhoid fever or small-pox, a change of physicians is made and this goes on until the patient gets well or dies. In these circumstances it is impossible to expect unity of the medical profession, for there is no common knowledge or scientific purpose to hold it together, and medical ethics are not even dreamed of. * R e a d at the C .M .M .A .

It has been recognized that the delicacy and complexity of the professional relations of a doctor with the patient and with the patient’s family necessitate a code of ethics more particular and specific than the general moral rules which govern ordinary human conduct, although based upon it. One of the earliest, if not the earliest of these codes, is the Hippocratic Oath (circ. B.C . 460— B.C. 380), of which the British Medical Journal k s recently reprinted the following full translation.

But more and more it is falling upon medical associations, general arid local, to take the necessary measures to protect themselves Medical Ethics in China. 681 and the honor of the medical profession against those of their number to whom gain, or reputation is .the first and. only consideration. In Great Britain the General Medical Council keeps vigilant watch over the conduct of doctors, and for any breach of ethical rules the penalty is swift and severe. In America there is no Council with punitive powers; it is left to the medical associations to protect the profession. To such an extent is this carried that our friends the parasitologists have recently compiled an ethical code entirely for their own use. This does not imply that the parasitologists find it harder to be virtuous than the rest of us, but the nature of their work in identifying and naming multitudes of newly-discovered organisms with all the conflicting claims which such work engenders makes a special code necessary. The difficulties in forming a code with which all will agree and in enforcing its observance are very great. In the first place, rules of medical ethics upon which even religious, honorable men hold different opinions are very numerous. We need not be disturbed by this as if it were evidence of moral perversity or backward moral development. It is much the same as when soldiers are fighting for a noble cause but do' not agree as to the motives and reasons why they fight for it, and it is well knowm that among theologians, all of them good men, there is much dissension when it comes to the formulation of ecclesiastical and doctrinal statements. In the second place, observation of the spirit of the code is far more, important than apparent conformity to the letter. A physi cian may say and do things of which his brethren may not wholly approve, but if he is a man of honor there may be no serious con sequences. On the other hand, a physician who is not thoroughly honorable may evade or violate every provision of the code and yet be so clever as to furnish no evidence to warrant his professional ostracism. In China there is a further difficulty : when a physician does violate medical ethics, there is no power, State or medical, which can punish him in any way. With regard to honest differences of opinion on ethical questions, some instances will now be given, for discussion of them is most necessary if we intend to compile a code for the guidance of the medical profession in China. We think it will become evident that we should confine ourselves to a few fundamental moral principles 6S2 The China Medical Journal. and that we should deal with the whole matter in a kindly, sympathetic spirit, being fully aware that the lack of unanimity is a disadvantage to those who assume moral leadership. P r o f e s s io n a l C o n f id e n c e s . Upon the question whether professional confidences shall be held inviolate or not, there is much diversity of opinion, not only between the medical profession and the State, but in the profession itself. The large majority of physicians contend that the knowledge and confidences obtained by medical men in the course of their pro fessional duties should be held as sacred and inviolate as the con fidences reposed by penitents in the priests of the Roman Catholic Church, or in other ministers of religion. But in some countries, as in England, it is held that in the interests of public justice a medical man can be compelled to disclose professional confidences. In a recent volume of essays (1922), Lord Birkenhead, a former Lord Chancellor of England, declares that no case can be made out for privilege when privilege may come in contact with law. The physician must tell all he knows about his patient, no matter what pain the telling may cause innocent people. On the other hand, when public interest does not demand such disclosures, the State will punish heavily any medical man who discloses the information he has obtained in his professional capacity, even though it is given to members of his own family^ and to no one else. For instance, a famous English obstetrician and gynecologist, called to attend his sister-in-law during the absence of her husband in a distant land, considered he had found indubitable evidence of misconduct. He told his wife so, and said that he wished she and other members of his family7 would have no further social intercourse with her and stopped an annual allowance (£500) which he had been giving her. The lady felt very much aggrieved and retaliated by bringing an action against her brother-in-law. She obtained the handsome sum of £12,0 0 0 by way of compensation and consolation. In China, we imagine, the elderly ladies of the clan, energetic and eloquent, would have taken a very active part in the dispute, and it would have gone very hard indeed with the sister-in-law. Instead of winning a large sum of money, her career would have been short and bitter, and probably she would soon have sought peace at the bottom of the nearest well. Medical Ethics in China. 683 But is the State always justified in requiring the disclosure of medical confidences ? A few years ago, one of the eastern States in America passed a law requiring that in every case where it came to a physician’s knowledge that abortion had been attempted he was to notify the State authorities. What may be the consequences ? A girl in a moment of weakness is led astray and becomes pregnant. To hide her shame, for she would rather die than have her condition made public, she goes to an irregular practitioner; an operation is performed and septic infection follows. A regular practitioner is then called in. Is he to notify at once the public authorities? If the patient believes that he is going to publicly expose her misdeeds she will not call him in ; she will prefer a thousand times to keep her shame hidden, whatever the physical consequences to herself may be. To obey this law rigidly may therefore indirectly' cause her death. Members of the medical profession are divided on the point, whether their duty to the State or their duty to the patient should take precedence. The difficult subject furnishes another problem : Suppose a family physician knows that a patient of his, who is suffering from a virulent venereal disease, is about to marry an innocent girl whom he has known and cared for from infancy. Is he bound to keep his knowledge of the prospective bridegroom’s condition a profound secret ? Ought he not to inform the parents of the girl that at all costs the marriage should not take place? In answer to the solemn injunction of the Church : “ If any man can show any just cause why they may not lawfully' be joined together, let him now speak, or else hereafter for ever hold his peace,” is he bound to remain silent? Interpreting the code of medical ethics strictly', perhaps he ought to keep his knowledge secret. But there are not a few medical men who openly declare that whatever the code may state, their duty is to do all in their power to prevent the marriage. Even the little Code of Medical Ethics adopted by* the American Medical Association, in regard to this difficulty, practically makes a strategic retreat from the main position in the words : “ There are occasions, however, when a physician must determine whether or not his duty to society requires him to take definite action to protect a healthy individual from becoming infected because the physician has knowledge, obtained through the con fidences entrusted to him as a physician, 01 a communicable The China Medical Journal. 6 8 4 disease to which tlie healthy individual is about to be exposed. In such a case, the physiciau should act as he would desire another to act toward one of his own family under like circum stances.” In China, such questions are hardly likely' to arise for some time to come, for in this country there can be no secrecy. As Arthur Smith says in “ Chinese Characteristics” : “ Every Chinese individual is a mere cog in a vast system of machinery. He has relatives beyond all count or remembrance. His wife has as many more. His married children add to the ever-widening circle. By the time he is sixty years of age, a man is related to hundreds upon hundreds of individuals, each of whom is entirely conscious of the relationship and does not forget or ignore it. Not only does all this army of relatives feel themselves entitled to know all the details of one’ s affairs, but the relatives of the relatives—a swarm branching into infinity^— will perhaps do the same. . . . There are no. secrets in China. Everybody crowds in everywhere — if not in sight, then ‘ behind the arras.’ Everyone who can get access to them, reads every dispatch he can see. He reads ‘ private’ letters in the same way. ‘ W h at!’ one exclaims, ‘ not let one see? There must be treason, stratagems and spoils in anything which is not accessiblc to everyone.’ The wise Chinese adage applies to all : ‘ If you would not have it known that you do it, do it not.5 ” P r e s e r v a t io n of H um an L if e . Perils of Child-birth.— In a way it is strange that religion itself should cause differences of opinion on ethical questions. For example, in those desperate cases of child-birth where it is necessary that either the life of the mother or child must be sacrificed in order that both shall not perish, the Roman Catholic physicians, in obedience to the directions of their church, sacrifice the mother to save the child, because it is believed that the child’ s eternal welfare depends on its being baptised. On the other hand, Protestant physicians, who have not the same terrible anxiety concerning the future destiny of the child, hold that the mother’ s life is of much more value to the community and therefore sacrifice Medical Ethics in China. 685 the child.* According to ancient custom, we- think that in such an emergency in China the father has the right to decide the question. The patria potestas gives him great power over the wife and absolute power over the children. He may' not only- chastise, but even sell, abuse or kill them. (Von Mollendorf, Fam ily L ife of the Chinese.) If the infant in peril is a boy, we believe that to secure the rites of ancestral worship the father would unhesitatingly declare in its favor; whereas iu the case of a female infant, who is relatively oi little value because when a girl grows up she passes on her marriage wholly into another clan and can perform no ancestral rites for her ancestors, probably the verdict would be adverse to-her existence. Infanticide.— This brings us to another problem which mayr involve Chinese doctors in ethical difficulties if they* become aware of the circumstances. To what extent is infanticide practised ^ C u r io u s ly , after th is p ap er had been w ritten , the D ecem ber (19 2 2) n u m b er of the Amer i c an Journal oj Obsictrics and w as Gy nec ol ogy received , iu w h ich is a rep ort of a d iscu ssio n of th is v e r y point at a m edical m ee tin g.

In any event, this is usually an affair which is managed by the native midwives. Perhaps it is seldom that an infant’s life is terminated by active means. Exposure and neglect may do all that is required. “ Thou shalt not kill, but need’ st not strive, Officiously to keep alive.” On inquiry, we have not heard of any Chinese physicians being involved in these affairs. Artificial Abortion.— Passing further back towards the genesis of human life, there is the practice of abortion. By' the laws of all civilized and Christian countries this is generally' regarded as a crime. Yet circumstances arise which sometimes seem to make it justifiable to relax the stricter dictates of law and morality in certain cases. Questions of this kind arose during the recent great war. If in the conquest of a city7 a weak innocent girl is outraged by a drunken enemy soldier, ought she to be burdened with the shame and suffering of undesired offspring ? Of course the correct reply is, that she must allow nature to take its course; and some will add that it is only by and through the sufferings of innocent women and children that war will ever be abolished. Artificial abortion is not unknown among the Chinese, for in former times it was punished with great severity. “ Abortion is not capitally punishable and a person administering the noxious thing is only liable to transportation for life, even though the woman dies. If the share taken by the offender was merely to procure the noxious thing, and although fatal results ensue, the sentence of one hundred blows and three years’ transportation will be imposed, comniutable in the case of a female offender by a fine.” (Alabaster, Chinese Criminal Law.) On inquiry we have not heard of Chinese foreign-trained doctors giving medicines or using other measures to cause abortion. However, in any code of medical f It w o u ld a p p ear from the case of th e G io ro T 'a n g W u - t ’ u th a t it is no offence to k ill an ille g itim a te c h ild if the k i llin g be done at or before birth ( H .

Voluntary Restriction of Conception.—Concerning the con ception of life there is the question as to the morality of restriction. Upon this point there is a very sharp difference of opinion in Western lands. The Roman Catholic church condemns restriction and I believe the Church of England with its affiliated Churches officially does the same. On the other hand, there are physicians and good people among the laity who contend that children should not be brought into the world’unless they can be reasonably provided for, and certainly that the physically and morally unfit should not be allowed to perpetuate their kind. A missionary lady in a letter to the North China Daily News recently wrote in favor of this Mal thusian doctrine, and her words almost implied that it should form part of the Christian missionary propaganda. With regard to the Chinese, the great mass of the people are still quite ignorant of this restriction, but before long they may hear of it.* Some time ago we received circular letters from Chinese in America urging the abolition of early marriage among the Chinese and the restriction of childbirth. On inquiry I find that, at present, Chinese doctors are not practically interested in the subject. A d v e r t is in g . Advertising by physicians is generally condemned because it is held that a physician should make headway solely by sterling un obtrusive methods, not by having trumpets blown before him. Yet there are many and subtle ways of evading this restriction. It is * T h e in e v ita b le ch an ge has a lre a d y com e. “ S tr a n g e a s it m a y seem , the t a lk on b irth co n tro l, u n w elco m e even in m a n y W e stern co u n tries, is h a v in g a la r g e au d ien ce in C h in a , w h ere th e C h in e se so c ia listic conception of th e f a m ily m ig h t be e x p ected to fu rn ish the stro n g e st o pposition to it.

Many medical books and papers have been written which are of no earthly use except to make known the knowledge and abilities of the writer, whose qualifications and honors occupy half the space of the title page. Then we are all familiar with the expedients of Bob Sawy^er, the famous character in one of Dickens’ novels. After an extremely riotous career as a medical student, when he began practice he suddenly became a model of decorum. He attended church on Sunday morning, but he so arranged matters that in the middle of the service his office boy would come rushing into the church with horror and dismay depicted 011 his countenance, to summon his employer to an imaginary* patient. Thereupon Dr. Sawyer would leave the church with becoming gravity , giving the impression that he was bowed down with the cares and responsibilities of a very large practice. The members of the congregation, perhaps not displeased with the momentary- diversion, especially7 if it happened during the delivery of a dull sermon, would look at each other significantly as if to say?, “ Bless me ! someone taken suddenly- i l l ; what a very busy- man Dr. Sawyer must b e !” We cannot help smiling, yet advertising in every shape and form must be closely scrutinised. Among the Chinese, advertising a physician is in accordance with well-established custom and tradition. On recovery- from an illness, a grateful patient often sends a very- laudatory notice of his physician to the newspapers; if he is somewhat dilatory, it is easy for the phy-sician to stimulate him to the performance of the custom. If the patient is extremely grateful, he will present his benefactor with a huge tablet, gorgeous with gilt and lacquer, proclaiming in large characters his marvellous virtues and abilities. This is carried through the streets publicly, so that all may see, to the house of the doctor, to whom it is presented with much ceremony?. Afterwards the tablet is hung in a conspicuous place in his reception room. It is doubtful if this custom would be tolerated in the West, but among physicians in China, both foreign and Chinese, although ethics ought not to vary with latitude and longitude, disapproval is not likely to be hearty and unanimous. There are few foreign missionary physi- Medical Ethics in China. 689 ■cians who have not accepted these tablets*; not in the least because we desired advertisement, but. because the tablets were evidence to us that we were winning the friendliness and confidence of the people^ and therefore that the .-help we.could give to the sick and suffering among them would, be all the greater. To refuse the tablet would be regarded as unfriendly and. perhaps give rise to sinister suspicions. We know' of one-missionary lad}', not a physician, who with hex husband began missionary work in a far inland station where the people were hostile and prejudiced. She opened a dispensary for the treatment of simple ailments, but the attendance was small. The chief mandarin of the city watched the mission. After some time he called the lady in to attend-his little daughter who had been ill for a long time. The child eventually recovered her health completely. The father was very much pleased and, to show his appreciation, lie went to the house of the missionary in full official state, in his sedan -chair with umbrella, and a retinue before and behindhand presented her with a very handsome tablet; he also issued a friendly proclama tion. The attitude of the people in the city toward the Christian missionaries completely changed. The dispensary patients rapidly increased in number and the lady and her husband were most success ful in their Christian work. If ever the end justifies the means, did not the giving of a tablet in this case merit approval? Where is .the line to be drawn? At any rate the incident may help us to understand the perplexities and difficulties of Chinese doctors when ithere is an apparent conflict between Chinese and Western customs. A ll we can sa}- is, certain forms of advertising should be proscribed. It is reported that some oi the Chinese physicians have very large sign-boards outside the front door and much electric illumina tion. We have heard somewhere of an ideal commonwealth, where it was the law that on the death of a patient the doctor who attended ihad to place an additional lamp on the front ot his house. Accordingl}7 some doctors' houses were brilliantly illuminated every »evening. This may have served for an advertisement, but prospective patients were likety to be chilled when they discovered ±0 what the illumination was really due. Perhaps in the long run advertising always defeats itself. We hope so. Unfortunately, many foreign physicians, of all nationalities, advertise themselves in the daily newspapers, which makes it the more difficult fpr some of the Chinese to see wherein advertising is wrong. ÓQO The China Medicai Journal. T h e Ph y s ic ia n a n d H is R e m e d ie s . Secret Preparations.-—According to the medical ethics of the West, a physician is forbidden to derive any financial benefit from the sale of surgical instruments or appliances which he may invent* and he should have no pecuniary interest in secret or proprietary medicines. The reason is plain. Whatever can be done to relieve human pain, misery, and disability should freely become the common property of all. Hence the sale of instruments and proprietary medicines is nearly always undertaken by commercial firms. In China, public opinion on this point is different. A s already said, the whole armamentarium of a native physician often consists of a few secret prescriptions. Some are undoubtedly of value, but judging by my own experience it is almost impossible to obtain a copy of them. It seems quite natural, therefore, that young Chinese doctors, even those who have been foreign-trained, should prepare and sell their own medicines of which they alone know the composition. Sometimes, we are sorry to say, the bottles are labelled with a statement that the medicine will cure the disease for which it is given. This custom is cruel and deceiving when the patient is in the advanced stage of a disease such as pulmonary tuberculosis. A recent lawsuit in Shanghai (K iang v. Koseal) shows the necessity of dealing with this subject. Ambiguous Guarantees.— Another reprehensible practice which, is said not to be uncommon, is that physicians give a guarantee in the form of a pao ih ( ^ HI ) to their patients. This Chinese term seems to be ambiguous. It may mean that the physician, gives a guarantee that he will cure the disease, which is the interpretation usually given to it by the patient; or it may simply mean that the physician will attend the patient until he gets well, if ever he does get well, which is the interpretation usually given toit b}? the physician. This is a custom which ought to be abandoned. Protection against Venereal Disease.— Some physicians prescribe certain precautions and applications with a guarantee that: a man by using them will obtain immunity from the physical consequences of immorality. In Europe and America opinion is hopelessly divided as to the propriety of these preventive measures, good honorable men being found on either side. Those who regard venereal disease apart from all moral considerations, solely as a dreadful disease which infects not only erring men but also- Medical Ethics in China. 691 innumerable innocent women and children, advocate preventive measures. Those to whom the disease is indissolubly linked with moral sanctions, cannot and will not approve preventive measures. In England, where there are two large societies both fighting venereal disease, but in bitter antagonism over this question, a strong committee has been recently appointed to investigate the whole subject and make whatever recommendations it deems necessary, ignoring absolutely all moral considerations. These recommendations will probably be adopted by the medical profession and it will be left to the people to decide whether they are ethical or not. Without leaning to one side or the other, it may be proper to point out that the way in which we deal with this matter may have a very important bearing upon our work as missionaries in this non-Christian land where the moral standard is high. In India the Mahatma Gandhi, who is regarded as a saint by hundreds of millions of the people who are powerfully influenced by him, has recently inveighed against the scope of Western medicine. He bluntly states that “ hospitals are institutions for propagating sin,” because when people know that ailments and diseases caused by wrong-doing can be removed they are encouraged to sin. It is true that much of our work does lie in relieving or curing the miserable consequences of ignorance, folly and sin, but most certainly nothing is done by medical missionaries to justify Gandhi’s contention ; on the contrary, every possible effort is made to lead the erring to repentance and goodness. Perhaps more ought to be done to show our opposition to the social evil and to the wrong social conditions upon which much of it depends. S um m ary of C r it ic is m s . On the whole, judging by the answers to inquiries which we have made, and remembering that China is passing from one form of civilization to another with consequent weakening of the old standards and imperfect realization of the new, and that the Chinese medical profession is being slowly formed during this period of unsettlement, we think it is a matter for thankfulness that among the foreign-trained Chinese practitioners, the ethical state of affairs is not very much worse. The most serious of the charges are the following : advertising ; the luring away of patients from one another; merciless criticism of the knowledge, judgment and 6gi The China Medical journal. methods of the physicians called to attend a case, before them; th^ preparation and sale of their own medicines: the composition of which is kept secret; giving ambiguous guarantees to patients. This is not a very dreadful indictment. Still, we. should do all we can to help our Chinese colleagues, or else matters may become very much worse later on. “ if they do these things when the wood is green, what will they do when the wood is dry? ” To bring the discussion to a practical issue the following suggestions are respectfully offered : First, that a small committee be appointed to draft an ethical code composed of a few simple, comprehensive rules. These we can discuss and decide upon at our next Conference. In this paper no attempt has been made to define medical ethics fulty and precise^ because so much depends on current opinion. But there are three principles, regarded as the foundation of medical ethics, which we may take as a guide : (a) in the relation of a medical man to his patients, their welfare and interests should be his highest consideration; (b) toward his colleagues, he should obey the Golden Rule, “ whatsoever ye would that men should do to \7ou, this do ve even so to them ” (St. Matthew vii, 12 ); (c) in his relation to the State he should obey all lawful authority, in accordance with the precept, “ Render therefore unto Csesar the things that are Caesar’s ” (St. Luke xx, 25). The suggestion has been made tljat the code should be incorporated in the Consitution to serve as a guide to the membership and as a requirement to which candidates for membership shouid, either tacitly or avowedly, promise to conform. 2. Having compiled an ethical code, the next step is to secure its observance. Here we come across a serious difficulty. The Chinese doctors who are determined to go their own way regardless of what others ma}' think, will care nothing for our code or anj? other,code, or for merely moral opinion of any kind, and reputable practitioners cannot restrain them. All we can do is to help those who wish to conform to our standards. How can this help be given? This is the main point. ; One way is to broaden the basis of our Association so as to include within its membership all phj^sicians of good standing in China, whatever their nationality,mav be, who are willing to con- Medical Ethics in China. 6 9 3 form to our rules and requirements. This may mean the sacrifice to some extent df our religious exclusiveness. But to help others and for the sake of the moral issues involved, is not the sacrifice Worth making? <<;Except a grain of wheat die, it abideth alone.” After all, the surrender need not be very great. Our Association could still remain a distinct religious unit, even in a larger organization. Of course such a change ought not to be made with out the most careful and leisurely weighing of all that can be said for and agaiiist it. Hence we suggest that when a committee is appointed to revise the Constitution and By-laws of our Association —the revision is certainly needed—it shall be requested to consider this question as part of its work and report to the next Conference.* 3. With the adoption of an ethical code it should be under stood that the Executive Committee has full power to investigate all alleged' cases of professional misconduct and to expel from the Association those who refuse to observe its rules. 4. The Council on Medical Education might be asked to con sider the question whether sufficient importance is given to the teaching of medical ethics in all medical schools in China. F o r e ig n P h y s ic ia n s and F o r e ig n N u r ses . This paper is already very long, but there is one other matter to which it has been requested reference should be made. It is said that in not a few hospitals throughout the country there is a certain amount of friction between the foreign physicians and the foreign nurses concerning the extent to which the nurse in her work is independent of the doctor. The root of the trouble seems to be that both are engaged in the larger work of Christian evangelization in which both stand on an equal footing, and on their appointment as * D u r in g the C o n feren ce the fo llo w in g R eso lu tio n s w ere p asse d u n a n im o u sly .

In kindness and justice to all concerned there must be no haziness or ambiguity on this point. In all matters relating to the care and treatment of the sick and injured the physician stands first, and it is the duty of the nurse to follow kis instructions fully and loyally. Even when a somewhat inexperienced Chinese physician is in charge of a hospital we do not see that any other ■coarse can be suggested. On the other hand, the physician should remember that the nurse is very highly trained ; that probably she has been in a position •of authority at home, and that in the mission field she is also in a position of authority with Chinese nurses under her. Th eve fore if he is wise he will not be harshly authoritative, but will endeavor to obtain her full and friendh7co-operation and give her his confidence. In the training of native nurses, she should be given full authority and freedom. All that is required is tact and sympath}-. If it is necessary, however, we suggest that the standing committee of physicians ana nurses appointed several years ago be requested to compile a few simple rules to govern the relations between doctors and nurses in mission hospitals in China. C o n c l u s io n . This brings our paper to a conclusion. The whole subject of medical ethics is very difficult and controversial, but as we all have the wel fare of our profession at heart and are extremely anxious that the Chinese medical profession shall in all respects be equal with the profession in the West, our discussion this morning will be sure to fasten upon the points of central importance and we shall reach conclusions that will be helpful to all.

S. D. Bhablia, M . D.

Opening of New Union Hospital, Huchow. 695 OPENING OF NEW UNION HOSPITAL, HUCHOW. On June 4th, 1924, the new buildings of the Union Hospital, Huchow, in the province of Chekiang, were formally opened. The main address was given by Dr. J. V. Latimer, who traced the early history of the medical work, particularly mentioning the coming of Dr. Eubank, of the Baptist Mission, and later the representatives of the SouthernMethodist Mission, including Dr. J. B. Fearn of Shanghai, and the present members of the hospital staff—Dr. F . P. Manget, Dr. C. D. Leach and Dr. Oscar Nelson. Other speakers spoke of the splendid co-operation that has existed between the various bodies that have made possible this achievement. The buildings have been put up by the Rockefeller Board, the Southern Methodist Mission, and the American Baptist Foreign Mission Society. The land was in great part the gift of the local gentry, who are represented equally with the two Missions on the Board of the Hospital. The plant includes hospital, out-patient buildings and power house. A building for the Chinese staff is already started. This plant, which was constructed and equipped with every modern convenience throughout at a cost of nearly $200,000, is considered by competent men to be the finest hospital building in Chekiang and Kiangsu provinces, aside from Shanghai. (See frontispiece.) In fact, it would be hard to find one better in all China, with the exception of Peking. The main building is a magnificent structure, of fireproof construction, having wards and rooms for 100 patients. It contains a well-equipped operating pavilion, laundry and kitchen. The latter attracts particular attention with its white tiled sinks and stoves. Modern bathrooms are generously supplied for wards and private rooms. Water, hot and cold, is in use in all the buildings. The main building is connected by a covered passage-way to the dispensary building, which is classical looking in its style of architecture. It resembles a small Carnegie Library, with its pillars and rounded balcony over the entrance. Appropriate remarks were made by the military and civil heads of the city, a message was read from the Governor of the province, and a ringing speech was made by the head of the Chamber of Commerce. 6g6 \The China Medical Journal. ne."j e a iitren t ilßeöicai Híterltuire.

The treatment of a severe case of anthrax by serum is described, the patient being completely cured in a few days.. He was a work man in a tannery, aged 22, and had been handling Chinese hides. When seen he had had a swelling on the right side, of the lower jaw for three days; it extended from the lobe of the ear to the chin, and from the lower ej-elid to the middle of the neck. Over the centre of the horizontal ramus there' Was a typical oval black scar surrounded by the usual vesicles. The patient’ s general condition was good, his temperature was 10 0 .20 F ., and pulse 100. He received 40 c. cm. of serum between November 17th and 20th, given in daily doses of 10. c. cm. In addition, compresses saturated in I in 1,000 mercuric chloride solution were applied locally, and each day 4 or 5 c. cm. of 2 per cent, phenol solution were injected at four “ cardinal” points of the periphery. Eight days after the commencement of treatment the oedema had almost completely disappeared, and one week later he was completely cured ; the slough had separated, leaving a pink depression 1 cm. in diameter. Bodin quotes statistics which show that the mortality of anthrax is low in those cases treated prior to the fourth day of the disease. A C A U S E OP P A IN IN T H E K N E E .

Sadolin describes a condition which, he says, is often mistaken for arthritis of the knee, although there are no signs indicative of a lesion of the joint. On walking the patient complains of pain referred to the back of the patella, and there is frequently a history of excessive walking up and down stairs or walking upstairs with a heavy burden. In several of the author’s cases the pain had gradually become so troublesome that work had to be given up, but rest, even rest in bed had not helped much. This condition, w'hich may be unilateral or bilateral, forms a remarkably definite clinical picture which the author associates with a lesion of the median head of the gastrocnemius. He has found that if this median head is massaged for five minutes at a time every other day for about three w^eeks the symptoms disappear without any other treatment, even in cases . which have been refractory to rest, baths, and massage of the joint and thigh.

Jour., November, 1922.) we are indebted for the suggestion that opening and draining the thoracic duct may assist surgical measures in serious cases of general peritonitis. He assumed that the chief cause of toxaemia in peritonitis was the flow of toxic Ijnnpli into the left subclavian vein, and went far to prove this in dogs suffering from gangrenous appendicitis by diverting this stream to the surface of the neck. He published a successlul case of lymphaticostomy in a girl with pneumococcal peritonitis. Cooke records a case of his own in which recovery ensued after lymphaticostomy in an attack of peritonitis apparently hopeless. He makes the following comments : (1) The thoracic duct is not very easy to find, because it is delicate in texture and thinner than one expects. After the exposure by dissection one is glad to have confirmation in the living subject by the presence of beads of lymph. In this case the beads were honey 3-ellow at the time of operation; two days later the discharge had the usual appearance of thin dirty milk. (2) The paucity of lymph in the first twenty-four hours in this case is explained by the fact that the patient was depleted of fluid b}' starvation and by a large faecal vomit; it was only after continuous rectal saline for twenty-four hours that lymph began to flow freely. No measures were taken to stop the flow of lymph, and this subsided in a week. Costain states that the lymphatics on the right side restore the circulation.

In discussing the advantages and disadvantages of drainage in acute appendicitis, Brockman points out that in many cases success or failure depends upon the general resistance of the patient and not upon drainage. The advantages of dispensing with the drainage tube are the less frequent occurrence of faecal fistulre and delayed convalescence. Secondary haemorrhage, he says, is rarely encountered and no residual 'abscess developed in his undrained cases. Intestinal obstruction occurred six times in his series, all following drainage. Convalescence is both shorter and more plea sant when drainage has been avoided. The problem of drainage depends largely on the state of the peritoneum; if there is to be closure without drainage it is necessarjr to leave behind an intact peritoneum. The chief indication for drainage is the age of the patient : children of twelve years and under, with a gangrenous appendix and purulent fluid in the pelvis, will not stand closure so well as adults with similar conditions. The degree of toxaemia is a valuable piece of evidence and can be estimated from the general 6g8 [The China Medical Journal. appearance of tlie patient; cyanosis is a bad sign and often foretells a fatal ending. Where drainage is necessary three methods are available : local drainage when invagination of the appendix stump is insecure; pelvic drainage with the use of the Fowler position; and safety-valve drainage when a potential abscess is present and a tube passes to the parietal peritoneum as an outlet for pus. Though the peritoneum may be closed in many cases, the abdominal wall often requires drainage; each layer of the incision should be drained by a series of rubber tubes. It is found in actual practice that the peritoneal cavity can be closed in most adults without drainage, but in children it should be drained by the safety valve tube.

The management of a case of post-operative obstruction after an attack of acute appendicitis presents one of the most anxious and difficult tasks with which the surgeon has to deal The follow ing plan of treatment, which Rayner believes should in all cases be adopted in th? first instance, is based on the fact that the obstruc tion is rarely a complete one and that the intestine will frequently recover its funcliou if relieved of some of its load. 1. All nourishment and drinks by mouth are stopped, but chewing of fresh fruit (orange, grape pulp), etc., is encouraged. 2. Subcutaneous infusion of saline solution. 3. Evacuation and lavage of stomach by stomach tube. Morphine, too, in many instances will be found beneficial, despite the apparent contraindication to its use, in producing rest and sleep. For the subcutaneous infusion, of saline solution Souttar’s apparatus answers admirably; the rather stout needles fitted to this can be painlessly introduced by previously injecting novocain through a hypodermic needle at the selected site. About three pints should be introduced in the first twelve hours. The passage of the stomach tube is an unpleasant task with a very poorly patient, especially with a child, but its use is of the greatest value. B y retaining the tube in a position for a few minutes after the stomach has been emptied it is often possible to withdraw several ounces more of intestinal contents. The drainage of the stomach may need repeating in twelve or twentjz-four hours. COLON A D H E S IO N S S IM U L A T IN G C . D a v is o n , M . D a v is o n and A P P E N D IC IT IS D .G .

The symptoms were vague abdominal pains. X-ray examination revealed a definite alteration ill the con tour of the ascending and transverse colon, which seemed to be caused by bands of adhesions producing partial or complete ob struction of the large bowel. The findings are definite, and laparotomy reveals the mechanical condition exactly as shown by the radiograms; operative correction of the pathological condition quickly relieves the subjective symptoms. The etiology of the condition is still somewhat doubtful, but the condition is evidently inflammatory and due to colonic stasis; chronic appendicitis often accompanies the condition, but it is not a cause. In most cases ptosis of the transverse colon is found and is probably an important factor. Stasis in the colon leads to band formation at the point of least resistance in the bowel wall. Relief is obtained by careful dissection of the adhesive bands; raw surfaces are covered by peritoneum. The patients are made to lie on the left side and the bowels are kept active to prevent new adhesions from forming. A C U T E IN T U S S U S C E P T IO N IN C H IL D R E N . T h o m p s o n , Brit.

Thirty-eight of the patients recovered. 1. Eighty-eight per cent, of cases occurred in the first twelve months of life. ,2. Sixty-two per cent, occurred between the fourth and the eighth month. 3. The ileo-csecal type only includes those cases where the intussusception apparently started at the ileo-ciecal valve and where this remained as the apex (28 per cent). 4. The majority of cases started as ileo-ileal (60 per cent), in which the last portion to be reduced was ileum. The commence ment of the intussusception in the ileum was recognised as a well defined dimple. Of these, eight cases, or r6 per cent, progressed only to the ileum; they have been called “ ileo-ileal ” ("that is, ileal or enteric). The remaining 22 cases (44 per cent) were made up of two intussusceptions— the original an ileo-ileal which, when it reached the ileo-caecal valve, was superseded by a second which had the ileo-cascal valve for its apex (that is, an ileo-ileo-caecal intussusception.) 5. The jejunal type of intussusception described in so many textbooks was not met with in this series. It is found post m o r t e m in children dying from other diseases. It is probably of no pathological importance. 6. The ileo-colic type was the most fatal (two deaths out of four cases). 700 The China Medical Journal. 7. Perhaps the ileo-colic type may occur in those cases where the coscum is less mobile; at any rate, in two of these cases great difficulty was experienced in delivering the caecum to the abdominal wound. 8. Ten cases required resection, because of irreducibilily or strangulation. Of these, three recovered and are still well. One other patient lived nineteen days and then died of broncho pneumonia. The remaining six cases died without recovering from the initial and operative shock. CHRONIC IN T U S S U S C E P T IO N IN C H IL D R E N O w e n , Brit. Med. Jour. M a y 24, 19 2 4 . Chronic intussusception in children is a somewhat rare complaint. A typical case is described as follows : “ O n a p a rtic u la r d a y the ch ild seem ed to h a v e p ain in the abdom en an d vom ited once or tw ice. D u r in g the n e x t fe w d a y s he o c ca sio n a lly vom ited, g e n e r a lly in asso ciatio n w ith a c o lic k y p ain .

T h e tem p eratu re th ro u gh o u t has been n o rm a l.” The diagnosis is made by feeling the sausage-shaped tumour, which varies in consistence under the fingers at different times, and by the sense of unnatural emptiness in the right iliac fossa. The condition may be mistaken for chronic appendicitis, tuberculous peritonitis, “ bilious attacks” and other complaints. The treatment is reduction by operation. In the event of the intussusception being irreducible or gangrenous, or both, the various operations for these conditions—namely, short-circuiting, removal of intussusception through the ensheathing layer, or resection with end-to-end union, wiil have to be considered, always on the assumption, of course, that the patient’ s condition is good and that the relations inside the abdomen can be made out.

At a meeting of the Section for the Stud}T of Disease in Children, of the Royal Societj* of Medicine, on May 23rd, Mr. R.H .A nglin Whitelocke gave his presidential address on “ posture” in relation to therapeutics and prophylaxis generally. He cited instances of postures due to occupations of various kinds, those neces sitated by certain diseases of the pulmonary and cardiac systems, and by disorders of the abdominal viscera, and referred to the three Current Medical Literature. 701 postures so much used in medicine and surgery—namely, the Trendelenburg, Sims and Fowler positions. All these positions had proved valuable in treatment, but Mr. Whitelocke had found that patients, especially children, suffered no harm if allowed to lie in the position most comfortable to them, and made a more rapid and easy recovery. Nurses should be instructed to allow patients to assume the posture of greatest ease. He knew of at least three cases in adults in which death had immediately supervened upon the patient being raised up into the Fowler position from which he had slipped. It was well recognised how almost impossible it was to maintain this position with children. The fact that drainage of the abdominal cavity did not seem to depend upon gravity, but upon intra-abdominal pressure and vital processes, had interested Mr. Whitelocke, and from his personal observations he had been led to the conclusion that a forced posture was unnecessarj? and frequently harmful. H Y P E R T R O P H Y OF T H E PR O ST A T E . The Statistical Department of the Johns Hopkins Hospital, Baltimore, has issued a preliminary report on the etiology of benign hypertrophy of the prostate gland. The purpose of the study is to show that with the aid of modern statistical methods the minutest detail which it might be desirable to know in the course of a thorough investigation of a special problem can be collected and made available for tabulation in every conceivable manner, with the minimum amount of effort. For this purpose data from 997 cases of prostatic hypertroph}’ have been transferred to punch cards for a monographic study. This research has been carried out with great thoroughness by Dr. Mary Gover, and certainly constitutes a valuable contribution to our knowledge of a condition that has so far proved a pathological mystery. The mean age of operation in cases of benign enlargement is 66.72 3rears, the period during which the main part of the abnormal growth in the prostate takes place being between 45 and 75 years of age. Single men do not appear to be as liable to the trouble as married, but, on the other hand, when hypertrophy occurs the prostate becomes as large as in married men. Previous affections of the genito-urinarv tract are comparatively rare, and childhood diseases and certain infections of later life do not appear to have anj? relation to the condition. Those who pursue sedentary occupations are no more likely to suffer from enlargement than those engaged in active work, whilst alcohol bears no relation to the disease. These results, although all of a negative kind, are nevertheless of considerable interest, since thejr show that some of the factors that have been supposed to influence the development of enlargement of the prostate actually play no part in its production.—Brit.

The problems of opium poisoning, chronic and acute, are always before the medical missionaries of China and it has been a great grief to us all to watch the steady recrudescence of the growth and use of the drug in recent years. In view of this and especially in connection with the meeting of the League of Nations’ Narcotic Committee in November of this year, a great effort is being made by the Anti-opinm forces, both Christian and non-Christian, to rouse opinion both in China and outside this country to the supreme importance of this question. As known to most of us, the only true solution of the question is the world-wide reduction of poppy cultivation to the amount that will guarantee sufficient of the drug and its alkaloids to meet the world’ s needs for medicinal and scientific purposes, and that this solution should be adopted at the coming meetings of the League of Nations is our earnest prayer and aim. To commend it convincingly it is essential that evidence should be before the League that the recrudescence of the growth of the poppy in China is entirely against the will of the people and that the best elements in this country are entirely opposed to the traffic. The medical missionaries of China have always been among the leaders iu the opposition to the habitual, unnecessan? use of opium and it becomes us to use every effort in the coming months to help the good cause. All that can be done at headquarters we are doing already. A Memorial to the League of Nations represent ing the medical opinion of China on the use of opium is being drawn up and signed on behalf of tbe National Medical Association, as representing the Chinese physicians, and on behalf of the China Medical Missionary Association, as representing the foreign physicians in China, by their respective Executive Committees. However, this is not sufficient. Each one of us in our respective places can do our little to help the good work along. The ways suggested for this are as follows : — r. To help in the districts in which we are placed to rouse public opinion and to make an effort by petitions or otherwise to influence the Government on the subject of poppy planting. 2. To obtain accurate information on the subject of the amount of poppy growth being carried on in our district and to transmit such information to the Honorary Secretary of the International Anti-Opium Association, Dr. W. G. ¿Aspland, Peking. 3. To. obtain photographs illustrative of the present opium situation both as to growth and transportation of the drug. 4. To obtain accurate documentary evidence of illegalities in connection with the traffic with a view to steps being taken to put a stop to them. Correspondence. 7'o5 .. Gorresponfccnce.
