Wide segmental overlapping innervation o fa f f e r e n t nerves was established as i n e任erent nerves. And yet afferent nerve 五 hers from a viscus may spread widely i n the sympathetic trunk and enter the spinal cord at several l e v e l s , from which e任erent nerves run to the rectus muscles o f both s i d e s . Experiments of u n i l a t e r a l sympathectomy show that a few a任erentf i b e r s may c r o s s to the other s i d e . And there i s a relationship between the l a t e r a l i s a t i o no f the visceromotor r e 但exand c ontralateralisat ion o fv i s c e r a l pain (SMITHWICKe ta l ) a s well as between these and i n i t i a ll o c a ls i g r i (KIMURA). M y experiments o f spinal anesthesia and i n j e c t i o no f alcohol into the subarachnoid s p a c e , show that the vagi probably do not conduct impulses from the abdominal v i s c e r a except emetic impulses.
