PLATE XIX. 



FIGURE 1. 



Common type f fibre arrangement in the gyrus fornicatus. 



From a transverse section of that gyrus above the middle of the corpus callosum. 



Z = zonal layer. S = supraradiary layer. B = line of Baillarger. R = radiary zone. The brackets 

 and figures to the right indicate the corresponding position held by cell layers. 



The general poverty of fibres is evident. ~. 



FIGURE 2. 



Common type of cell lamination in the gyrus fornicatus. 



Drawn from a section of the gyrus fornicatus above the middle of the corpus callosum. 



1, plexiform layer. 2, .sparsely supplied layer of small pyramidal cells. 3, medium-sized pyra- 

 midal cells. 4, large external pyramidal cells. 5, stellate layer almost unrecognisable. 6, internal 

 large pyramidal cells. 7, fusiform cells.
