Ventrally it is grooved for the vn-ethra; dorsally it is convex, and an- teriorly it becomes smaller and has a curved fibrous The glans penis is very long, extcmling over the entire length of the os penis; its anterior part, the pars longa glandis, is cylindrical, with a pointed free end; behind this there is a rounded cnhirgement, the bulbus glandis. Both are composed of erectile tissue. The two veins arise from the bulbus glandis, pass backward on the dorsum penis, and imite at the ischial arch. A small muscle (M. compressor vena dorsalis penis) arises from the tuber ischii on either side; the two converge on the dorsum penis near the bulbus glandis. They compress the dorsal veins, and may also tend to elevate the penis and thus assist in copulation. The other muscles offer no features worthy of special description. ' They are present in the cat, and are the size of a pea. - In the young subject it has a prolongation composed of hyaline cartilage, which becomes fibrous Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Sisson, Septimus, 1865-1924.
