The nerve cells and fibers were studied in preparations fixed in 

 Flemming's fluid and stained with iron hematoxylin. As in forms 

 previously studied, the general structure of the ganglion in a way 

 duplicates the structure of the nerve cells, in that a general reticulum 

 forms a framework for the other structures in both. It is hard

in individual cases to distinguish the supportive structures from 

 the conductive, but the fibers and fibrils in or outside of the nerve 

 cells run in longer straight lines — that is, they do not form so much 

 of a meshwork, although they may branch and intertwine to some 

 degree both within and outside the nerve cells. Large strands or
