Case II. A middle aged gentleman had an abscess on the side of the face just in front of the ear. Suppuration was advanced and the fluctuation was marked. Silicea had done some good as it had controlled the pain. The cavity was aspirated by a surgeon several times but it continued to refill. After three weeks there was no abatement of the difficulty. The integument took on a new feature, becoming bluish, mottled with great burning and sharp cutting pains. The hardness was extending and the opening gave out a bloody thin excoriating fluid of foul smell. He was chilly and nauseated and had symptoms of pyaemia. After one dose of Tarentula cubensis 12x an immediate change for the better took place, no more pus formed and he was well in ten days. The discoloured localization became bright red and then faded to the natural colour. The nausea and general pyaemic symptoms were greatly relieved within twelve hours. No more medicine.
