When this ulcer has continued for some time, it either begins slowly to cicatrize, or more frequently the discharge diminishes, and becomes thicker; it then hardens into an elevated scab, of a dirty white, or yellowish colour. This continues for a considerable time, and then crumbles off, leaving the part covered with a smooth purple cicatrix. This description corresponds to the mild scrophula, or the struma mansueta of the older writers; but occasionally, especially if a bone be diseased below the ulcer, the sore has a more fiery appearance, the surface is dark coloured, the margins soft, elevated, and inflamed, and sometimes retorted. The discharge is watery, the pain very considerable, and the surrounding skin inflamed. This has been called the struma maligna, and was said to be marked by the greater degree of hardness and inequality in the tumor, varicose veins, and pulsatory pain: It was likewise said to be contagious. But although occasionally this state of the scrophulous ulcer be preceded by a hard and painful tumor, yet it is not necessarily so, but rather seems to depend upon a disease of the parts below, which generally are bones, cartilages, or tendons in a morbid state; and hence this overacting scrophulous sore is most frequent over the smaller joints, particularly the toes. Sometimes the scrophulous abscess, after bursting, forms a sinus, the mouth of which ulcerates, and assumes the appearance of the specific ulcer; but the track of the sinus remains in a suppurating state. This not unfrequently is connected with a diseased bone, or cartilage, or tendon. Scrophulous tumors and ulcers more readily disappear during the winter, and return again on the approach of summer; but this is by no means an universal law of the disease. It is likewise observable, that swellings of the glands are very apt to subside pretty rapidly in one place, and appear equally quickly in some other glands, in the vicinity of these originally affected. Ulcers likewise frequently heal upon the appearance of the disease in other parts.
