Remove the clothing with the greatest care. Do not pull, but carefully cut and coax the clothes away from the burned places. Save the skin unbroken if possible, taking care not to break the blisters. The secret of treatment is to prevent friction, and to keep out the air. If the burn is slight, put on strips of soft linen soaked in a strong solution of baking-soda and water, one heaping table spoonful to a cupful of water. This is especially good for scalds. Illustration: Fig. 159.—Dotted Line showing the Course of the Femoral Artery. _Carron oil_ is one of the best applications. It is simply half linseed-oil and half lime-water shaken together. A few tablespoonfuls of carbolic acid solution to one pint may be added to this mixture to help deaden the pain. Soak strips of old linen or absorbent cotton in this time-honored remedy, and gently apply. If carbolized or even plain _vaseline_ is at hand, spread it freely on strips of old linen, and cover well the burnt parts, keeping out the air with other strips carefully laid on. Simple cold water is better than flour, starch, toilet powder, cotton batting, and other things which are apt to stick, and make an after-examination very painful.

The ears, toes, nose, and fingers are occasionally frozen, or frost-bitten. No warm air, warm water, or fire should be allowed near the frozen parts until the natural temperature is nearly restored. Rub the frozen part vigorously with snow or snow-water in a cold room. Continue this until a burning, tingling pain is felt, when all active treatment should cease. Pain shows that warmth and circulation are beginning to return. The after effects of a frost bite are precisely like those of a burn, and require similar treatment. Poultices made from scraped raw potatoes afford much comfort for an after treatment. 369. Catching the Clothing on Fire. When the clothing catches fire, throw the person down on the ground or floor, as the flames will tend less to rise toward the mouth and nostrils. Then without a moment’s delay, roll the person in a carpet or hearth-rug, so as to stifle the flames, leaving only the head out for breathing. If no carpet or rug can be had, then take off your coat, shawl, or cloak and use it instead. Keep the flame as much as possible from the face, so as to prevent the entrance of the hot air into the lungs. This can be done by beginning at the neck and shoulders with the wrapping.
