. The anatomy and physiology of the human body. Containing the anatomy of the bones, muscles, and joints; and the heart and arteries . sthat coat does to the bodv of the testicle. Understanding the nature of the peritoneum, we may learnthe meaning of this looseness of the outer coat of the turning to the introductory section of the abdominal mus-cles, Ave find that the inside of the sac of the peritoneum issmooth, and forms no adhesion; whilst the outer surface, beingin contact with the substance of the several viscera, has a con-nection with them bv a common cellular membrane. Now,as the inside of the peritoneum does not adhere, as the surfaceof the peritoneum (which in this first plan if> towards C,) issmooth, and has no tendency to unite with the surface of theviscera; so neither has the surface of the peritoneum at D, thetendency to unite with the peritoneum (or the surface of thealbuginea) at B, Avhen it descends to meet it; consequenththe coat of the intestines may be represented in this secondplan, thus : Second and Third Plans of the Testicle. 2cl. Plan of the Testicle. 3d. Plan of the Testicle. OF THE TESTES. 29^ In the first plan we had the situation of the testicle in thefcetus represented. In the second plan, we have the middlestage of the descent represented: and, in the third, we havethe full descent. In the second figure, A is the body of thetesticle, B is the first peritoneal covering or tunica albiiginea,which can be easil\- traced, reflected off from the loins at C ;again, D is the portion of the peritoneum, which having de-scended before the testicle, is presently, when the testicle hasfully descended, to become the second, or vaginal coat ofthe testicle ; F is the continuation of the peritoneum upon theinside of the abdominal muscles. In the third figure of this series, we find the testicle A hasdescended into the scrotum ; that it has one coat covering it,which we recognise to be the same with B, in the first figure,and that the p
