Actual Size 21 X 16 mm.] The central gray matter occupies a position mimediately beneath the floor of the fourth ventricle and serves to form the lateral ventricular bound- ary. At the lateral extremity of the section is a dense mass of fibers, the superior cerebellar peduncle (Scp), an index concerning the degree of coordinative control which the animal possesses. Compared with the other intermediate primates, the gibbon shows no marked increase in this par-.
