This is a serious disease; it is a solitary inflammation of the cellular tissue and skin, presenting a flat, spongy swelling of a livid hue, and attended with dull heavy pain. It varies in size, and its progress is slow. Like the boil, it appears more often upon the neck, the shoulders, the back, buttocks, and thighs. The constitutional symptoms are low throughout, and the attendant fever is apt to be typhoid in character; prostration and delirium often terminate the case. It most frequently attacks high livers of an advanced age.

TREATMENT. -- During the formation, apply either fomentations and poultices, or cold water dressing. An incision in the form of a cross should be made free and early, which may be followed by caustic applications, in order that the dying parts may thoroughly be removed. After this is done, the wound is to receive ordinary treatment.
