Fig. 44 A diagram of the connections of the olfactory tracts and the lateral 
forebrain bundle of the alligator, based on a longitudinal section of the hemis- 
sphere in the plane indicated by the line A-A’ of figure 2. The olfactory tracts 
are printed in red, the lateral forebrain bundle in black. 
Fig. 45 <A diagram similar to figure 44, but taken farther ventral and in a 
somewhat different plane, passing through the level of the hippocampal com- 
missure as indicated by the line B-B’ of figure 2. 
Fig. 46 A diagram of a longitudinal section through the forebrain of the alli- 
gator taken in a parasagittal plane, to illustrate the relations of the olfactory 
and somatic centers. Olfactory fibers red, somatic fibers black.
