PLATE XV. 



FIGURE 1. 



Type of cell lamination in Temporal Area No. 1 (audito-sensory) ; the drawing is from a 

 section of the most anterior of the transverse temporal gyri. 



Layers 1, 2 and 3 call for no special remark, but attention must be directed to layer 4 ; 

 it is a prominent lamina containing elements of larger size and more richly endowed with chromn- 

 philic particles than cells of the same layer in any other part of the temporal region. 



An uncommonly good representation of the layer of stellate cells (5) is a characteristic feature 

 of all temporal cortex and it is well seen here. Special note must be taken of the point that 

 the internal or substellate layer' of large pyramidal cells is virtually non-existent in this particular 

 area ; in consequence of this the layer of spindle-shaped cells assumes an unusual depth.

Compare with figure 1 and notice that the cells in layer 4 are cm the whole much smaller.
