Baudelocque * objects to the lancet as a means of opening these abscesses; and proposes, in its place, to apply a caustic composed of equal parts of Caustic Potash and quicklime, made into a paste with spirit of wine. This is smeared over the whole of the diseased surface, and allowed to remain on for five minutes. The eschar is thrown off in the course of a few days. The objection to this application is the great irritation to which it gives rise. In British practice, the lancet is generally preferred.
