When the coats of the testicle are taken off, it is found to consist of innumerable delicate white tubes, which when disengaged from the cellular membrane that connects them together, and steeped in water, exhibit a most astonishing length of convoluted vessels; they appear to consist of one continuous tube, convoluted in partitions of the cellular membrane. When the Tubuli come out from the body of the testicle, they run along the back of it and form a net work of vessels called Rete Testis; it is supposed that by the net work the semen is conveyed from the testicle. The continuations of this Rete Testis have been denominated Vasa Deferentia, which, ending in a number of Vascular Cones, constitute what is called the Epididymis. The Vasa Deferentia, after forming three conical convolutions, unite and form larger tubes, which ultimately end in one large excretory duct, called the Vas Deferens. The following description relates to the accompanying sketch.
