Plate III.— CAUDATE NERVE CELLS. 

 Fig. 1. 



/ 



Diairam to show the course of the fibres which leave the caudate nenre cells, 

 a a are parts of two nerve cells, and two entire cells are also represented. Fibres 

 from several different c^lls unite to form single nerve fibres b b b In passing 

 to^vards the periphery these compound fibres divide and sub divide, the re- 

 sulting sub-divisions passing to different destinations. The fiue fibres resulting 

 from the subdivision of one of the caudate processes of a nerve cell may help to 

 form a vast number of dark-bordered neives, but it is, I think, ceriain that 



NO SrSGLE PROCESS EVER FORMS ONE ENTIRZ AXIS CYLINDER.

A diagram of a caudate nerve cell, showing the principal lines which diverge from 

 the fic-res at the point -^here they become contmaous with the substance of the 

 cell. These lines may be traced from any one fibre across ihe ceil, and one 

 or more of them may be followed into every other fibre which proceeds from. 

 the cell. The tracts are nut connected with the bioplasm of the nerve cell.
