Note 7 — PART FIRST. OF INFLAMMATION. (continued 2)

[To prevent mortification blisters have long been a favourite means with American surgeons. The practice originated, I believe, with the late Dr. Physick, of Philadelphia, early in the present century. To do good, they should be large enough to cover, not only the whole of the inflamed part, but a considerable portion of the surrounding surface, and to be kept on until they have produced thorough vesication. Blisters are scarcely less serviceable to arrest mortification, after it has made some progress, but in this case they should be placed in contact with the sound skin, not with the dead, as they cannot, when this is done, be productive of any good.

To expedite the sloughing process, allay the unpleasant fetor, and promote the formation of healthy granulations, I know of no remedy that will answer so well as the nitric acid lotion. It should vary in strength, according to the exigency of the case, from four to twelve drops of the acid to the ounce of water, and a cloth wet with it should be constantly kept in contact with the affected part, taking care to wash it occasionally to rid it of the foul discharges with which it becomes from time to time impregnated. If necessary, a poultice can be placed over the rag. Under this treatment, particularly when aided by the liberal use of carbonate of ammonia, wine, brandy, and other cordials, I have often been astonished to witness the rapid changes that have taken place, in cases apparently of the most desperate character.—ED.]
