(.V»7m.) I, view of upper surface. II, view of lower surface: rhr, cerebrum; o, corpora quadrigemina, or bigeminal cbll, cerebellum; obi, medulla oblongata; h, hypophysis; opt, optic nerve. In birds the cerebellum is likewise reduced to a single median lobe, and is entirely uncovered by the cerebrum, and being single it possesses no lateral hemispheres; the pons varolii, or the transverse fibres which serve as a commissure for the cerebellar hemispheres, as in mammals, is likewise absent. The characteristics of the mammalian brain will be subsequently alluded to. The nervous system is composed of central masses which are in constant communication with different parts of by means of peripheral prolongations which act as oi'gans of conduction. The nervous system exists, therefore, under two forms—the central, composed largely of the so-called nervous ganglia, or nerve-cells, and the organs of conduction, or nerve-fibres. As already indicated, the peripheral termi- nations of the nerves are likewise in connection with corpuscular bodies,.
