The tunica vaginalis testis or peritestis^ is the next covering. A serous membrane lining the cavity and reflected over the testicle within ; it Was originally peritoneum, and is the seal of hydrocele. The testicles are the glands for the secretion of semen. They are two in number, oval in shape, and flattened laterally. They hang obliquely by the spermatic cord, being attached above the middle of the posterior edge; the right being higher than the left. The tunica alhuginea^ is the dense, white, thick, fibrous coat of the testicle, which gives it shape. In structure it re- sembles the dura mater or sclerotica ; ex- ternally it is covered by a portion of the peritestis, which is transparent and very closely adherent; from its internal face are given off numerous partitions called septula testes, and which uniting at the posterior edge of the testicle, form that prismatic ridge termed corpus Highmorianum? The testicle is formed by lobules, each placed within the spaces between the septulse. Each lobule^ consists of a tuhulus seminiferus, very finely convoluted. This tube becoming straight forms the vas rectum ;* the union of which makes the rete testis^ which is in the corpus Highmorianum; from the upper part of this rete proceed 15 or 20 tubes through the tunica albuginea ; they are called vasa efferentia ;^ each vas efferens is convoluted in a conical form, and termed comis vasculosus ; the union of the coni vasculosi forms the commencement of the epididymis. The epididymis^ is that vermiform ap- pendage encircling the posterior edge, as a crest upon a helmet. It is soft and formed of a single convoluted tube, originating by the junction of the bases of the coni vascu- losi. The upper extremity is the larger, Fiff. 103. and called sdoh r,7 and the lower is globus niinar.^ From the globus minor this tube ascends in a less convoluted form, under the name of the vas deferens^^ which forms one of the constituents of the cord. Connected with the epididymis is the vasculuni aberrans^^ a small, blind, convo- luted duct. 11
