Actual Proportion between Cerebrum and Cere- bellum.—According to Cuvier, the proportion of the cere- bellum to the cerebrum, by weight, in the baboon, is as 1:7; in the dog, 1:8; in the sheep, 1:5; and in the horse, 1:7. 662. Spinal Cord.—The essential difference between the spinal cord in man and the lower mammalia, is its greater length, and a narrow canal which runs longitudinally through the middle of it. Fig. 331. 663. Nervous System of Birds.—The brain of birds is characterized by the smallness of the hemispheres, though more fully developed than in reptiles and fishes. In the sparrow the weight of the brain to the whole body is as 1: 25 ; in the goose, 1: 300 ; and in the cassowary, 1:1000. It is destitute of convolutions, or in other words is perfectly smooth on its surface, and has large cavities or ventricles con- taiued in it: and, as in mam- mals, the mass of the brain is greater than that of the spinal cord. The pairs of the cerebral nerves are the same as in mammals; also the principal divisions are the same. The cerebellum, as in man, exhibits the arbor vitee when cut through vertically. 664.
