Fourth \'entricle. [Accession No. J. D. Section 515- A ' "-e 45 X 25 mm.] The cerebellar nuclei and particularly the dentate nucleus (Ndt) show a most striking advance (Fig. 303). Not only has there been a great increase in the size of this nucleus which represents the efferent transmission of cerebellar impulses, but it has also manifested that outstanding feature of specialization whenever cerebral expansion is necessan,-, namely, a greater tendency toward convolution. The nucleus dentatus in gorilla is much more highly organized in this particular than in either the orang-outang or chim- panzee. TTiis differentiation furnishes another reason for the claim that in certain details of its encephalic structure the gorilla stands nearer to man.
