_Lacerated and Contused Wounds_ require practically the same treatment; they must be thoroughly cleansed with a warm solution of some disinfectant, all shreds or loose and hanging bits of skin removed with scissors, then dust over the wound a powder made with powdered iodoform one part, powdered boracic acid eight parts, mixed together, a few layers of antiseptic gauze applied and the parts bandaged. When there is much discharge the dressing should be repeated twice a day, otherwise once a day is sufficient. Do not continue the compound iodoform powder for more than three or four days. After a week or so, if the wound is healing very slowly, apply instead of the gauze some boracic ointment on lint, which may be occasionally changed for the following lotion:— _Recipe_: Sulphate of Zinc, 1 scruple. Tincture Calendula, 2 drachms. Water to 8 ounces. This should be applied on a piece of lint doubled once and just big enough to cover the wound, which should be covered over with oil-silk and then bandaged. Repeat the dressing twice a day. When proud-flesh, or excessive granulations—that is, the newly-formed tissue to fill up the wound—forms and grows above the surface of the surrounding skin, nitrate of silver in the form of a stitch should be applied by just wiping it once across the surface of the parts. These wounds often take a long time to heal. In treating punctured wounds the principal thing to do is not to let the skin heal before the parts underneath have, otherwise an abscess is sure to form, and there is a danger of blood-poisoning. A puncture wound may be cleaned by being syringed out with a solution of some disinfectant, then a small strip of disinfectant gauze should be placed in the wound to prevent its healing. This is to be covered over with a few layers of gauze and a bandage applied. Repeat the dressing twice a day, and so long as there is any discharge the wound on the skin must not be allowed to heal. _Fistulous Wounds_ are sometimes very difficult to heal, and often require operating upon before they will do so—especially in cases of a fistulous wound in the anus which may extend to and open into the bowel. However, before submitting the patient to an operation try the following lotion:— _Recipe_: Chloride of Zinc, 6 grains. Tincture Calendula, 1 drachm. Water to 1 ounce. A little to be gently syringed into the wound once every other day. In cases of fistulous wounds the result of diseased bone, time must be given for the dead bone to come away. The application of hot linseed-meal poultices dusted over with powdered charcoal do good, but it is often a matter of weeks, sometimes months, before the dead bone separates from the healthy bone. When the case is very obstinate the services of a veterinary surgeon should be obtained.
