=Symptoms.=--With the exception of the local appearances, they are essentially the same in both of the above-mentioned forms. The characteristic feature of the disease is a _dermatitis_ with its peculiar _roseate_ hue, which it is impossible to describe in words. In tint it differs slightly from that noted in certain cases of erythema. It is, however, accompanied by an infiltration of the structures of the skin, so that the area which is reddened is at the same time elevated above the surrounding surface. Its edges are often irregular. As exudate takes the place of blood in the tissues, the red tint merges into a yellow. At this time there is more induration of the skin and tendency to pit on pressure. Vesication of this involved area is now frequent, the vesicles often coalescing and forming large blebs and bullæ, which fill with serum that may become discolored or purulent. When exposed to the air, unless the tissues become gangrenous, this serum usually evaporates and forms scabs. This disturbance of the skin is always followed after a number of days by desquamation. This infectious dermatitis shows a constant tendency to spread in all directions. Its most characteristic appearances are limited to the margin of the enlarging zone, while in its centre there may be evidences of recession of the disease. If it commences in the vicinity of a wound it will probably spread in all directions from it. Beginning in the face, it usually spreads upward; in the trunk, in all directions; if on the extremities it tends to migrate toward the trunk. _Wandering erysipelas_ is a term often applied to these phenomena. The _metastatic_ expressions of the disease have been described. When this affection attacks a recent wound the local appearances are not essentially distinct from those mentioned under Septicemia. The wound margins separate to a greater or less extent, the surfaces slough, and a characteristic seropurulent discharge occurs. Granulating surfaces usually become glazed--often covered with a membrane resembling that of diphtheria; deep sloughs may occur, undermining of wound edges, even hemorrhages from destruction of vessel walls. In rare instances, however, under the influence of the microbic stimulation granulations proceed faster than normal.
