TESTICLE (NORMAL ANATOMY). arise from" the nearest largest trunks, and enter the substance of the gland at its pos- terior part. The artery of the vas deferens, from which the gubernaculum is chiefly sup- plied, is nearly as large as the spermatic. The long course taken by the arteries and veins of the testicle when in the scrotum is thus ex- plained by the original site of the organ, to which circumstance must also be ascribed the sharp turn upwards of the vas deferens from the epididymis, the two being continuous in a direct line, whilst the testicle is in the ab- domen. Fig. Diagram of the gubernaculum and testicle previous to its descent. 1, the kidney; 2, the testicle; 3, 3, the peritoneum ' 4, vas deferens passing down into the pelvis by the side of the bladder; 5, the bladder; 6, the abdo- minal ring; 7, 7, Poupart's ligament; 8, pubic por- tion of the cremaster; 9, fibres of the cremaster arising from Poupart's ligament; 10, portion of the guberuaculuui attached to the bottom of the scro- tum. Between the fifth and sixth month of foetal existence, sometimes later, the testicle begins to move from its situation near the kidney towards the ring, which it usually reaches about the seventh month. During the eighth month it generally traverses the inguinal canal, and by the end of the ninth arrives at the bottom of the scrotum, in which situation it is commonly found at birth. The testicle, both during its passage to the ring and through the inguinal canal, carries along with it its original peritoneal coat, adhering by the reflexion of this membrane, during the whole of its course to the parts behind, in the same manner as whilst situated below the kidney. The testicle therefore does not pass directly and abruptly into a pouch prepared to receive it, but carries the peritoneum with it, con- tinuing to be connected to the parts behind by the reflexion of the membrane, between th
