(Fig. 639) it is seen to be arched from before backward, white in color, and com- posed substantially of transverse fibers. The middle part or trtincus (Truncus corporis callosi) slopes downward and forward and is thinner than the ends. The anterior thickened end, the genu, bends ventrally and backward and thins out to form the rostrum; the latter is continuous with the lamina terminalis. The pos- terior end, the splenium, also thick, lies at a considerably higher level than the genu. The dorsal surface is convex in its length, concave transversely; it forms the floor of the longitudinal fissure. It is covered by a thin layer of gray matter (Induseum griseum), in which are strands of longitudinal fibers (Striae longitudi- nales); the latter ar
