The cellular substance, that connects the dartos and cremaster with the tunica vaginalis, has been considered by some as an additional coat, and termed tunica vaginalis communis. The tunica vaginalis or tunica elytro'ides is a true serous membrane, enveloping the testicle and lining the scrotum; having, consequently a scrotal and a testicular portion. We shall see, hereafter, that it is a dependence of the peritoneum, passing before the testicle in its descent, and afterwards becoming separated from any direct communication with the abdomen.

The doited unfolded, according to Monro, measures as line forming base of this triangular much as thirty-two feet. As soon as the vas deferens quits the testicle, it joins the spermatic cord, passes upwards to the abdominal ring, separates from the blood-vessels on entering the abdomen, and descends downwards and inwards to the posterior and inferior part of the bladder, passing between the bas-fond of the latter and the ureter. It then converges tovvards its fellow along the under extremity of the bladder, at the inner margin of the vesicula seminalis of the same side, and ultimately opens into the urethra near the neck of the bladder.
