It con-sists of two symmetrical hemispheres joined together bya central constricted commissural portion. The uppersurface is flattened, slightly convex, and presents- twolobes,—a large anterior, the quadrate, and a narrowerportion, the semilunar. Along the median line is thetransverse commissure called the superior vermiformprocess, which begins at the anterior notch and termi-nates at the posterior notch of the cerebellum.

The inferior surface of the cerebellumis irregular and uneven. Each hemisphere presents fourlobes,—the tonsillar, digastric, slender, and posterior in-ferior. The inferior vermiform process is depressed, andpresents from behind forward the short commissure,the pyramid, the uvula, the nodule, and arching outwardfrom each side of the nodule is a lamina of white mattercalled tlie velum. At eacli extremity of the velum is theflocculus,—a group of miniature convolutions. The THE SPINAL COHD. 303 3Ncll
