xX 93. Arrow placed as in figs. 8 to 12. 
18 Goblet shaped cell from longitudinal section. 
19 Fusiform granule cell from longitudinal section. 
20 Stellate granule cell from longitudinal section. 
21 Fusiform cell from sagittal section of the olfactory bulb, showing neurite 
entering the crus. Golgi method. X 93. 
22 Transection through the middle of the right olfactory crus. Weigert 
method. »% 33. Thissection was drawn to show, particularly, the nervus term- 
inalis; the remaining fiber pathways do not come out so clearly as in other series. 
23 Transection through the caudal part of the right olfactory crus, immediately 
rostral to the cerebral hemispheres. Weigert method. X 33. 
24 Transection through the rostral portion of the cerebral hemispheres. Wei- 
gert method. ™ 17. This section shows the relation to the hemispheres, of the 
tracts of the crura.
