    for a class of diseases which appear under such various forms and degrees of intensity. The period of convalescence is generally long, during which, several diseases, especially hooping cough, anasarca, and chronic diarrhoea, may supervene. ERYTHEMA. Syn.—Inflammatory Blush; Tooth Rash; Gum; Intertrigo; Maculae Volaticce; Dartre erythemoide. Erythema is a non-contagious exanthematous affection, charac- terized by slight superficial red patches, irregularly circumscribed, and of variable form and extent. Although it may appear on every part of the body, it is most frequently seen on the face, the chest, and the limbs. It is generally confined to one or other of these regions, but it sometimes spreads over the whole body. Erythema usually follows an acute course, and its duration varies from a week to a fortnight. In a few rare instances it assumes an inter- mittent, and sometimes even an essentially chronic character. When it accompanies ague, or supervenes during the paroxysms of inflammatory fever, its duration will be longer or shorter, according to that of the diseases with which it co-exists. Symptoms. — Erythema is seldom preceded by febrile symp- toms. It appears in the form of patches, of variable extent, and of a light superficial red colour, very different from the deep and in- tense hue of erysipelas. The redness disappears for a moment upon pressure of the finger. There is little or no heat or pain. The stains or patches are sometimes accompanied with either an indolent or a painful and circumscribed degree of tumefaction, which invests the eruption with a peculiar aspect, and constitutes two distinct varieties of erythema. One of these varieties (Erythema papulatum) occurs most fre- quently in females and in young men, on the neck, the chest, the arms, the back of the forearm, and the back of the hand. The patches are small, seldom exceeding the size of a fourpenny-piece ; they are irregularly rounded and slightly prominent like papulae. The red colour soon changes into a violet hue, especially in the centre of the patches. In- the course of thirty-six or forty-eight hours the tumefaction diminishes, and nothing remains but the red
