![textures. In the latter case, and also when the abscess has been opened by incision, there is no such risk. It is true that the thin denuded mucous mem- brane, though in the first instance remaining entire, is generally perforated by ulcerative absorption before long, indeed, seldom more than a few days after eva- cuation of the abscess. But then the parietes of the cavity are impervious to the urine which flows through, without obstruction in front, and without force from behind greater than is requisite for its discharge. Ab- scess at the anus, having no fascia to impede its course to the externa] surface, almost invariably discharges its contents through an opening in the integuments of the hip. If at this period the cavity be carefully ex- amined by introducing a finger into the rectum and a probe into the sinus of the abscess, it may be as- certained, if any doubt should remain, that the mucous lining is perfectly entire; although, as in the case of the urethra, perforation is almost sure to en- sue subsequently, from ulceration of the thin detached membrane which has formed the inner wall of the abscess. The fistula in ano, however, does not be- come complete, or communicate with the mucous canal, so soon as that in perineo, often requiring several vreeks for the accomplishment of this, especially when the abscess has been opened by a free incision.](https://iiif.wellcomecollection.org/image/b21307933_0066.jp2/full/800%2C/0/default.jpg)
