That portion of the peritoneum which immediately surroundsthe testis is, by the above process, cut off from its continuity with * On the Structure of the Gubernaculum, &c., by Mr. Curling, Lectureron Morbid Anatomy in the London Hospital, in the Lancet, vol. ii. 1840-41,p. 70. 640 DESCENT OE THE TESTIS. the peritoneum, and is termed the tunica vaginalis; and as this mem-brane must be obviously a shut sac, one portion of it investing thetestis, and the other being reflected so as to form a loose bag aroundit, its two portions have received the appellations of tunica vaginalispropria, and tunica vaginalis reflexa. The descent of the testis is effected by means of the traction of themuscle of the gubernaculum (cremaster). The fibres, writes Mr.Cui-ling, proceeding from Pouparts ligament, and the obliquus in-ternus, tend to guide the gland into the inguinal canal; those attached Fig. 207.* Fig. 208.t

to the OS pubis, to draw it below the abdominal ring; and the processdescending to the scrotum, to direct it to its final destination.During the descent, the muscle of the testis is gradually everted,until, when the transition is completed, it forms a muscular envelopeexternal to the process of peritoneum, which surrounds the gland andthe front of the cord. The mass composing the central part of thegubernaculum, which is so soft, lax, and yielding as in every way tofacilitate these changes, becomes gradually diffused, and, after thearrival of the testicle in the scrotum, contributes to form the loosecellular tissue which afterwards exists so abundantly in this part,The attachment of the gubernaculum to the bottom of the scrotum isindicated throughout life by distinct traces. * A diagiam illustrating the descent of the testis. 1.
