. The diseases of the genital organs of domestic animals. Veterinary medicine. The Male Genitalia 3 down their peritoneal fold which extends from the guber- naculum below the origin of the spermatic artery in the lumbar region. It is attached anteriorly to the spermatic cord and posteriorly to the scrotal wall, to form the mesor- chium which constitutes a membranous median partition in the posterior part of each scrotal sac from the fundus to the internal inguinal ring, as shown in Figs. 2, 3, and 4. The processus vaginalis, in everting, pushes before it on the lateral side the as yet invisible cremaster which quickly de- velops when the testicle descends into a bright red, highly functioning muscle. The scrotal sac thus consists of two distinct groups of tissues, the general integument composed of the skin and dartos and the intra-abdominal portion con- sisting of the parietal peritoneum and the cremaster muscle with the intervening fasciae. The two groups of structures remain easily separable throughout life. The surgeon in performing the ''covered operation," when castrating ani- mals with scrotal hernia, avails himself of this distinction. Fig. I.—The Testicle and its Attachments.
