_To Dress recent Wounds._—When the apparatus is ready, the piece of tin is cut and fitted to the wound, so that it shall overlap the wound to a small extent on all sides; then a piece of lac plaster, large enough to overlap the tin one or two inches all round; this plaster may be cut and notched when the surface is irregular to make it lie pretty closely; then strips of diachylon, about two inches broad, are cut ready. The parts around the wound are well cleaned; dirt and clots cleared from the wound with cold water, containing about 1 of carbolic acid to 40 of water, and the interior of the wound is freely syringed with water containing 1 of acid in 30 or even 1 in 20 parts. The sides are brought together with sutures, if necessary, in the ordinary way, and the tin laid on the wound; the tin is freely wetted with carbolic water, and the lac plaster laid over it and kept _in situ_ by strips of diachylon plaster. In dressing recent wounds the most dependent side of the lac plaster is left unattached, that the serous discharge, which is often copious, may readily escape. To receive this discharge, a piece of calico, soaked in carbolic oil, is laid over the wound now covered in, and all kept in place by a folded towel or a roller bandage. This oily cloth is to be changed from time to time as it gets soaked with discharge: at first this change is necessary every night and morning, but after three or four days once a day is often enough. The shell-lac plaster and tin need not be removed for a week unless the wound grow hot and painful, when they can be removed at any time if the surface of the wound is immediately smeared with carbolic oil, and kept well imbued with the antiseptic while it is being examined. Should it contain pent-up discharge, the sutures must be loosened and the discharge washed out by injecting the 1 in 30 aqueous solution. The tin and lac plaster may be then replaced, and the dressing renewed. The same precaution must be followed when the sutures have to be removed. Usually there is very little swelling and no pain, and the healing process goes on tranquilly if undisturbed. Should bruised parts slough, they may be trimmed away with scissors dipped in carbolic oil. When the wound has once been washed with carbolic acid, the antiseptic should not enter the wound a second time, as its irritant qualities excite inflammation in the wound.
