PLATE 4 
EXPLANATION OF FIGURES 
6 Transection through the middle of the right olfactory bulb. Weigert method. 
< 31. Most of the stippled periphery is filled with the unmedullated fibers of the 
olfactory nerve which are ending in glomeruli in this region. An especially prom- 
inent mass of such fibers appears dorso-laterally, forming the protuberance ‘a,’ 
as shown in fig. 1. 
7 Ganglion cell of the nervus terminalis. Golgi method. X 93. See fig. 124 
for the position of this cell. 
Sto12 Mitral cells of the olfactory bulb. Golgi method. ™X 93. In the cells 
from transverse sections an arrow points toward the center of the bulb; in sagittal 
or horizontal sections the arrow points diametrically away from the olfactory 
crus and toward the center of the bulb. Figs. Sand 9 are from transverse sections, 
figs. 10 and 12 from longitudinal section of the bulb. 
13. Fusiform cell from nucleus olfactorius anterior. Longitudinal section. 
Golgi method. »X 93. Arrow as in figs. 8 to 12. This neurone extends diagon- 
ally across the bulb, one end entering a glomerulus. 
14 Stellate cell from nucleus olfactorius anterior. Transverse section. Golgi 
method. 93. Arrow asin figs.8to12. Large numbers of these cells are found, 
most of which are connected with glomeruli; some of these glomeruli contain mitral 
cell dendrites, while many are small and are, apparently,formed only by stellate 
cell and olfactory nerve processes. 
15 to 17 Neurones from the nucleus olfactorius anterior. Golgi method. 
« 93. Arrow placed as in figs. 8 to 12. 
15 Stellate cell, connecting with a mitral cell glomerulus. From longitudinal 
section. 
16 Stellate cell from longitudinal section. Shows one dendrite in connection 
with a glomerulus, while the neurite extends toward the center of the bulb. 
17 Fusiform cell from longitudinal section.
