The amount of adipose and cavernoustissue is reduced in proportion. In the rams penis, the condition is similar to that in the dog, ex-cept that the adipose tissue occurs chiefly in the proximal portion, littleor none distally. Wethers penis contains fat in about the same amountas the ram, but less cavernous, and more fibrous tissue. Lambs penissimilar, except that the adipose tissue is less abundant. In the boars penis, adipose tissue is likewise found in considerableamount in the proximdl region, especially in the crura. Fibro-caver-

The corpora cavernosaof both sides are united into a single body. From the thick tunicaalbuginea fibrous trabecule extend inward, and unite in the center toform a fibrous core on each side.
