The rest, in Dr. McKay's words, makes the process quite plain.—L. T.] First Step: The Incisions. Figs. 8, 9.—The sharp point of the lower blade of the angular scissors is pushed into the tissues at L'; the blade is made to sink for half an inch into the tissues, and the left index-finger is placed in the rectum beneath the ' white line,' i.e., beneath the junction of the vaginal with the rectal mucous membrane. A cut is now made along the white line from L' to K', then from E' to E, i.e., along the junction of the skin, S, and the vaginal mucous mem- brane, P V F. The next incision is made from L' to L, then from L' to L, and then from E' to E. Second Step : The Reflection of the Vaginal Wall. Figs. 12, 13.—The incisions from 1/ to E', from E' to E, and from L' to L, having been made, we now find that the mucous membrane of the posterior vaginal wall, P V F, being how liberated, retracts, and we thus come to have formed a raw W-shaped surface. In order that we may increase the surface, it is necessary to gently snip round the edge of P V F, and by so doing we make a real flap of
