FROSTBITE  , a

form of mortification (q.v.), due to the action of extreme cold in cutting off the blood-supply from the fingers, toes, nose, ears, &c . In comparatively trifling forms it occurs as " chaps " and " chilblains," but the term frostbite is usually applied only to more severe cases, where the part affected becomes in danger of gangrene . An immediate application of snow, or ice-water, will restore the circulation; the application of heat would cause inflammation . But if the mortification has gone too far for the circulation to be restored, the part will be lost, and surgical treatment may be necessary .
