. The anatomy of the domestic animals. Veterinary anatomy. THE CEREBRAL HEMISPHERES 789 The fibers of the olfactory striae go to the piriform lobe and hippocampus, the trigonum olfactorium, the area parolfactoria, the subcallosal gyrus, and part of the gyrus fornicatus. The central connections of the olfactory apparatus are complex and are not yet fully understood. The anterior cerebral commissui-e contains fibers which pass from the olfactory bulb of one side by way of the medial striae to the bulb of the opposite side; also fibers which cross in it from the medial striae of one side to the piriform lobe of the opposite side. Many fibers pass to the hippocampus by way of the septum pellucidum, fornix, and fimbria. Other fibers pass in the column of the fornix to the mammillary body and thence to the thalamus by the thalamo-mam- millary bundle. The corpus callosum is the great transverse commissure whicii the two cereljral hemispheres through about half of their length. On median section.

(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 trimcus (Truncus corporis callosi) slopes downward and forward antl is thinner than the ends. The anterior thickened end, the genu, bends ventrally and backward and thins out to form the rostnun; the latter is continuous with the lamina terrainalis. The pos- terior end, the spleniiun, also thick, lies at a consitlerably 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 (Induseiun griseum), in which are strands of longitudinal fibers (Strise longitudi- nales); the
