THE FOREBRAIN OF THE ALLIGATOR 399 
Figs. 22-43 Characteristic cells from various parts of the forebrain and 
thalamus of Alligator mississippiensis as seen in Golgi preparations. 90. 
Fig. 22 A diagramatic sketch of the positions and relations of the various 
cell types found in the olfactory bulb. 
Fig. 23 Small mitral cells of the olfactory bulb (GI : 60). 
Fig. 24 Large mitral cell of the olfactory bulb (GL : 73). 
Fig. 25 Large goblet cell of the olfactory bulb (GI : 64). 
Fig. 26 Small goblet cell of the olfactory bulb (GI : 55). 
Fig. 27 Group of internal granule cells of the olfactory bulb. Note that 
one of the stellate cells sends its dendrites down into the plexiform layer and 
into the region, at least, of the glomeruli. The other does not send its dendrites 
outward beyond the mitral cells (Gl : 55). 
Fig. 28 A small stellate cell of the olfactory bulb (G1 : 96). 
Fig. 29 A goblet cell of nucleus olfactorius anterior (GI : 103). 
Fig. 292 A diagram showing the orientation of figure 29. 
Fig. 30 A diagram showing the orientation of the hippocampal cells. ‘The 
positions of the hippocampal cells figured (figs. 31-36) are shown here. 
Fig. 31 Correlation cell found in the dorsal part of the hippocampus at the 
anterior end of the hemisphere (GI : 104). 
Figs. 32 and 33. Small projection cells of the dorso-medial part of the hippo- 
campus (GI : 139; GI : 140). 
Fig. 34 Intrinsic cell of the hippocampus (GI : 140). 
Figs. 35 and 36 Double pyramid cells. These are the specialized derivatives 
of projection cells of the dorso-medial portion of the hippocampus. The cells 
figured are probably imperfectly impregnated (GI : 140; GL : 139).
