    a cul-de-sac, is then passed through the fistula, till the point comes in contact with the gorget; by cutting on this gorget, all the parts between the internal opening of the fistula and the anus are divided. The latter operation is seen in plate xlviii., fig. 3, in which the gorget is introduced into the rectum, held by an assistant; the director is placed in the fis- tula, and the surgeon, holding the bistoury in his right hand, is ready to continue the operation. In fig. 4, the next step in the operation is seen: a, repre- sents the rectum; b, b, the fistula; c, the gorget introduced into the rectum; d, the director passed through the fistula and towards the gorget; e, the knife introduced in the direc- tor, with its edge toward the gorget.
