This affection is characterized by a greater or lesser number of livid spots on the skin, from extravasated blood. In simple cases the effusion is confined to the skin and cellular tissues, mostly occurring on the arms, legs, and breasts. The spots at first are small, and resemble flea-bites. The countenance is pale, and the patient complains of debility, loss of appetite, irregularity of the bowels, and periodic fever. If allowed to progress, it will assume a form known as purpura hemorrhagica, in which the spots are longer, and resemble whip-marks or violent bruises. They are a bright red at first, but become purple or livid. A great variety of symptoms are presented by each case, and the disease is a very singular one.

TREATMENT. -- In the simple form a very liberal diet of fresh vegetables, out-door exercise, and some simple tonic, are all that is necessary. In the hemorrhagic character, quinine, in one or two grain doses, should be given every three hours. Diet should consist of green vegetables, salt meats, eggs, and the free use of lemonade. A liniment of camphor, whiskey, and turpentine should be externally applied. If internal hemorrahge occurs, give oil of erigeron, in five-drop doses, every half hour; or matico, in from five to ten grain doses, may be administered every twenty minutes until it ceases.
