branches, several cells in a single ganglion, as well as several 

 ganglia. At its termination, each terminal branch breaks up 

 into varicose twigs, which surround the type I cells in an end- 

 basket which has been shown to be within the capsule of the 

 cell. Similar end-baskets have been found, surrounding sympa- 

 thetic cells in both central and peripheral ganglia in all parts of 

 the body. As shown by Dogiel, Huber and others, they are 

 the telodendria of white rami fibers or preganglionic fibers and 

 are always intra-capsular. While these pericellular baskets have 

 been found by Huber (21) in the ganglia of the oesophagus as 

 well as in those of the intestine, he states that he believes that 

 not all the cells of these ganglia are thus connected to the cere- 

 bro-spinal system, since the number of baskets found has been 

 relatively small. 



The question of the character of the ganglia of Auerbach's 

 plexus in the intestine has been discussed by Langley and 

 Anderson (33), Kolliker, Huber, and others and, in spite of the 

 apparent failure of Langley's physiologic experiments, the 

 conclusion seems indisputable that these ganglia, as well as the 

 ganglia of the oesophagus which are analogous to them, are 

 sympathetic, since they correspond histologically in every re- 

 spect to other sympathetic ganglia and like them are connected 

 to the cerebro-spinal system by white rami fibers which termin- 

 ate in pericellular, intracapsular end-baskets about the cells of 

 the ganglia. 



The nerve trunks of the intermuscular plexus of the 

 oesophagus contain the white rami or preganglionic fibers, the 

 non-meduUated neu raxes of the sympathetic motor cells and 

 the neuraxes and dendrites of the sympathetic sensory cells 

 already mentioned ; in addition to these, they contain non-med- 

 ullated nerves, the neuraxes of sympathetic cells, whose cell 

 bodies are situated either in the ganglia of the oesophagus or in 

 more distant ganglia, the fibers forming a perivascular plexus 

 and terminating on the smooth muscle fibers of the vessel walls; 

 besides these, we find larger meduUated nerves, which pass 

 through the ganglia without making connection with any of the 

 cells and pass into the submucosa and mucosa to end as will be
