glia of any considerable size. Occasionally two or three cells may 

 lie close enough to exert some mutual pressure on each other 

 and flatten their adjacent sides (fig. 14), but generally they stand 

 at some distance from each other. The figure was drawn from a 

 slightly more crowded region than is typical in order to include 

 as many cells as possible in one drawing.

 factory nerve in adult nasal capsule of Amia. Taken from a slightly more crowded 

 locality than is typical. Toluidin blue stain. X 333. 



In a medium sized adult a little over one-third of a meter long, 

 there were found to be nearly one thousand cells that were attrib- 

 uted to the nervus terminalis beneath a single olfactory capsule. 

 The counting was done in sagittal sections of Nissl preparations, 

 cut thick, and generally only such cells were counted as showed 

 nuclei, in order to avoid counting a cell more than once. Fig. 14 

 is drawn from these preparations (toluidin blue stain), and shows
