or St Anthony's Fire, a redness of the skin attended with a sensation of heat or burning, and having a remarkable tendency to spread over the surface of the body. When unattended with constitutional symptoms, it is styled erythema. In the three other forms there is more or less constitutional disturbance. These forms are, 1st, Simple erysipelas, where there is a tendency to the formation of vesicles which break or dry up, leaving the skin either whole or slightly abraded. This form is often erratic, flying from one part of the body to another, lingering about the person for weeks or months. 2d, Phlegmonous erysipelas, in which the subjacent cellular tissue is involved, and often terminating in the formation of collections of matter, or even sloughing of the tissues. 3d, Edeematous erysipelas, attended with an effusion of serous fluid below the affected parts, and occurring chiefly in persons of impaired constitutions. In some situations this form is apt to terminate in gangrene. In the great majority of cases of this affection, a brisk purgative followed by tincture of the muriate of iron, fifteen to thirty drops five to ten times daily, combined with belladonna, if the disease has a tendency to spread, rapidly arrests the disease. In the phlegmonous form, hot fomentations of sugar of lead and opium, or of hot whisky and water, afford great relief, though, if matter form, it must be let out by free incisions. The edematous form requires the more liberal use of iron and quinine, with laxatives and generous diet.
