    111 birds, tlie cerebellum is large and very raucli more developed than in tlie fishes or reptiles. It is marked by circumvolutions or transverse lamellae, which vary in number, in different birds, according to the greater or less size of the cerebellum. According to Leuret,' the number of these lamellae is never less than ten nor more than twenty. Now, as regards the generative function, it will not, I think, be found that there is any direct ac- cordance between its power and the number of the cerebellar lamellae. In the chicken they number four- teen, and in the goose, sixteen. Yet the former is undoubtedly more salacious than the latter. In the pigeon and others of the dove family, they number six- teen, and in the magjDie, twenty ; but the former are remarkable for their excessive amorous passion, while in the latter it is by no means a noticeable character- istic. Among mammals the cerebellum reaches its highest state of development, and in man its utmost degree of size and comj^lexity of structure. But we find no cor- respondence between this organ and the sexual appe- tite such as Gall has attempted to establish. In the cat, for instance, the cerebellum is for a mammal slight- ly developed, the lateral lobes being very small, but no one will contend for the existence of slight sexual pas- sion in this animal. In regard to this point. Dr. Car- penter says: A friend who kept some kangaroos in his garden informed the author that they were the most salacious animals he ever saw—yet their cerebellum is one of the smallest to be found in the class (mammalia).
