Burns
Anything which excludes air without tainting the wound or irritating it further helps a bad burn. Carron oil — a creamy mixture of lime water and sweet oil — applied with a feather, then covered with cotton, either batting or absorbent, gives a measure of relief and is also healing. Soft old linen coated with fresh egg-white laid on and allowed to dry soothes pain. Even a covering with dry flour, if nothing else is handy, is better than leaving the burn bare. But if at all serious, or even is shallow and wide spread, call a doctor instantly, meantime keeping up heart action with stimulants in small doses often repeated.
