FFig. 37 Same region as figure 36 but on the left side of the brain. A drawing 
from a Golgi section to show the ependyma cells in the dorsal lip of the middle 
ventricular groove, and their curved processes. 
Fig. 38 Transverse section through the tuberculum olfactorium to show the 
grouping of cells in the islands of Calleja. From a section adjacent to that shown 
in figure 24. Magnification 110 diameters... The medio-basal angle of the left 
side and a small part of that of the right side are included. a, b, c, d, typical 
islands. e, an island in which larger and smallcells aremingled. In some islands 
similar to this the small cells definitely show the vesicular arrangement with 
lumina. f, a vesicle similar to those shown in figure 35. Only the nuclei are 
drawn.
