STRUCTURE OF THE CORTEX CEREBRI.

Barbary Ape (fig. 8.)—The most important grouping occupies the posterior ex¬ 
tremity of the frontal convolutions, and the upper end of the ascending frontal gyrus. 
Fig. 8. 
At the middle third of the latter convolution two other small areas are represented. 
The upper and anterior end of the larger group is continuous with a large formation 
extending over the anterior half of the paracentral lobule. Over all these areas the 
cells are large and richly clustered. The greater part of the unshaded portion of the 
figure consists of the transitional and six-laminated realms. 
The Ocelot (fig. 9).—Here the great ganglionic nests centre around the crucial 
sulcus, entering into the structure of its limbic and parietal boundary, and exhibiting 
cells of large size congregated in rich clusters, and so closely resembling those found in 
Fig. 9. 
the Cat that a full description would here be out of place. I subjoin, however, a table 
of measurements of these great cells at different points of the limbic and parietal 
boundaries of the crucial sulcus :—
