Figs. 1 to 7. A series of transverse sections through the hrain of adult 

 Kana pipieus prepared by the Golgi method, to illustrate the central course 

 of the nervus terniinalis. All except Fig. 1 are drawn to the same scale. 



Fig. 1. Through the olfactory nerves about 1 mm. rostrad of the olfactory 

 bulbs. X 60. 



Each olfactory uerve is broken up into numerous fasciculi, some of the larger 

 of which are indicated by the dotted outlines. A small proportion of the fibers 

 of the olfactory nerve (fila olfactoria) are impregnated, some of these fibers 

 being scattered singly among the fasciculi of the nerve, others aggregated into 

 more or less definite Inuidles. The fascicle marked n. tcrmiiiaUs on the left 

 side is unmixed with flla olfactoria ; on the right side the two fascicles so 

 designated are probably of mixed character.

Fig. 2. Through the olfactory nerves just at their entrance into the olfactory 

 bulbs. X 30. 



The most rostrally jilaced glomeruli occiipy the dorsal part of the section. 

 The fila olfactoria occupy the middle and ventral parts of the section and only 

 a few of them are impri'gnated. The nervus terniinalis is embedded in the 

 most ventral part of each olfactory nerve and all of its fibers are imi)regnated.
