It is covered by minute granulations, or by a dry, greyish crust, which if removed is quickly renewed. The discharge from the ulcerated surface is a thin, scant, sanious ichor, which is usually inoffensive. The ulcer bleeds easily when touched. The sensa- tions to which it gives rise vary in different cases. Sometimes there is severe, lancinating pain; at other times stinging or pricking sensations, which lead the patient to increase the irritation by frequent scratching. In the intervals there may be a dis- agreeable sensation of heat. In some cases there is little or no pain. In the onward course of the disease the ulceration extends downwards to the subcutaneous tissues, and causes destruction of the muscles and bones. Whilst in the centre and in the earlier-affected parts of the diseased area ulceration and destruction of tissue make steady progress, the disease is found in its primary stages on the circumference of the sore. In the border of the ulcer small papillary nodules are formed, with a scaly sui-face; and frequently these advance to the formation of tubercles or small tumours before they are involved in the extension of the original lesion. Eventually the lymphatic glands corresponding to the affected part become enlarged. They are at first felt as small, hard, movable, isolated tumours, producing, little inflammatory reaction. As they
