PLATE XI. 



FIGURE 1. 



Type of cell lamination in the visuo-sensory or calcarine area. 



Drawing from a section through the middle of the posterior calcarine fissure and from the 

 wall of that sulcus. 



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

 cells. 4, layer of large stellate cells ; these lie in the upper part, and the pale zone in the lower 

 half corresponds in position with the line of Gennari. 5, well-marked layer of small stellate cells. 



6, layer of giant cells, the solitary cells of Meynert, which are seen to be sparsely scattered. 



7, layer of spindle-shaped cells.

FIGURE 2. 



Type of cell lamination in visuo-psychic area. 



Drawing from a section of the superior occipital gyrus, midway between the top of the 

 parieto-occipital fissure and the posterior extremity of the hemisphere. 



The general cell wealth is striking. 1, plexiform layer. '2 and 3, small and medium-sized 

 pyramids. At 4 the numerous large external pyramidal or pyriform cells, specially referred to in 

 the text, are seen. There is a deep and sharply defined layer of stellate cells but no pallid zone 

 is seen above and below it, as in the calcarine cortex. Note also that the internal layer of large 

 pyramidal cells is wanting and that there is a complete absence of solitary cells of Meynert. 

 The fusiform layer (6) looks deep.
