    by a fine membrane, wliich strengthens the bottom of the sheath, and forms a kind of diaphragm, which prevents all com- munication between the sheath of the spermatic cord' and the tunica vaginalis of the testicle. The cremaster ... is a thin muscle or fleshy plane, which runs down round the sheath of the spermatic cord, and terminates in the tunica vaginalis testis. It surrounds almost the whole bag, and afterwards expands on the upper and outer part of the tunica vaginalis, where it is inserted and lost. It arises partly from the ligamentum Fallopii, and partly from the lower edge of the internal oblique muscle of the abdomen; and on this account, it seems sometimes to arise from the spine of the os ilium. ... It is covered by a very fine cellular membrane, detached from the outside of the aponeu- rosis of the obliquus externus round the opening called the ring. This membrane is lost in the cellular substance of the inside of the dartos. . . . This muscle is not always red, . . . (Ibid., n. 513 —522.) There are two particular nerves that accompany the spermatic cord; one comes from the lumbar nerves near the anterior spine of the os ilium; it makes a curve as it runs out of the abdomen through the muscles, and in its passage serves to distinguish the cremaster. The other of these two nerves comes from the renal plexus. (Ibid., n. 587.) 20. Heister. The testicles or didymi.... their coats are three : the cremaster or elevator muscle of the testicle: the tunica vaginalis, which loosely surrounds the testicle, and is from a process of the peritonaeum: the tunica albuginea, which is strong, closely connected with the substance of the testicle, and receives the spermatic vessels, and transmits them to the testicle. . . . The nerves of the testes are from the plexuses of the nerves of the pelvis, and from the lumbar plexuses. Nume- rous lymphatics may be seen in the part in a living animal. The substance of the testicles is vascular, consisting of the most minute vessels, which are the seminal vessels, and which are convoluted after the manner of intestines. . . . The testicles have apparently no glands in them. . . . The corpus Highmori in the human subject is at the back of the testis, but in the dog in the middle part; ... it is said to have a cavity for receiving the seed. . . . The two epididymides or parastatse . . . are oblong, almost cylindrical parts, lying on the upper border of the testicle,
