An incision is made in the scrotum over the fundus of the sac, large enough to admit a forefinger and the large needle used in the operation; the edges of the skin are to be separated from the fascia below for about one inch all round. The forefinger is then to be passed in at the aperture and pushed upwards, invaginating the detached fascia before it, and it must be made to enter the inguinal canal far enough to define the lower border of the internal oblique muscle stretched over it. A large curved needle (unarmed) is then passed on the finger as a guide, through the internal oblique tendon, the internal portion of the ring, and the skin of the abdomen; it is then threaded and withdrawn. Again, the needle (now with a thread) is guided by the finger and pushed through Poupart's ligament and the external pillar of the ring as before; while by a little manipulation its point is made to protrude through the same opening in the skin as before, a loop of thread is now left there, and the needle, still threaded, is again withdrawn. The next stitch, still guided on the finger, takes up the tendinous layer of the triangular aponeurosis covering the outer border of the rectus tendon close to the pubic spine; the point of the needle is then turned obliquely, so as to protrude through the original puncture in the skin a third time, the needle is then freed from the thread and withdrawn, thus leaving two ends and one intermediate loop of thread all at the one opening. These are so arranged that when they are tightened they draw together the sides of the canal; they are then secured over a compress of lint. The compress is removed and the stitches loosened, at dates varying from the third to the seventh day. Mr. Wood now uses wire instead of thread. It has the advantage of greater firmness, excites less suppuration, and may be left much longer _in situ_, in consequence of which there is less risk of suppuration or pyæmia, and more chance of a good consolidation of the parts.
