voluntary movements of his arms and legs; sometimes it was necessary to hold his hands, and at one time he appeared conscious, for he folded his arms as if making an effort not to raise his hands to the seat of pain. He coughed now and then, and seemed somewhat embarrassed with the blood in his throat. He was seated in a chair, but as there was no window in the operating theatre except the skylight, his head was obliged to be inclined rather backwards. He was leaned forwards once or twice, to allow him to get rid of the blood, and it appeared that he vomited some on one of these occasions. Towards the conclusion of the operation, and at a time when he was very little under the influence of chloroform, he fainted. He was laid down, and brandy was given to him. No more chloroform was administered after this time. He partially rallied from the syncope, but again became faint. The actual cautery was applied, but oozing of blood continued until the moment of death,—about half an hour after his removal into another room. During this interval, he was much exhausted; his pulse was small, and difficult to feel. He was tossing himself about in a restless manner, but there was no difficulty of breathing. He seemed quite conscious, doing as he was told, but, of course, could not speak, from the nature of the operation. I left a few minutes before the patient’s death. When he ceased to breathe, laryngotomy was performed, and artificial respiration exercised by the opening, with no beneficial result. In my opinion, this measure was not indicated, but of course it could do no harm. One of the surgeons who was present when the patient died informed me that blood entered his windpipe from the wound, when he became moribund. It was found during the operation that the tumour did not involve the superior maxillary or malar bones, but was situated behind them. In his address to the class immediately after the operation, Mr. Hewett estimated the loss of blood at sixteen ounces. It appeared to me to be much greater; besides that a great deal of blood would certainly be swallowed. After death, portions of the tumour were found still remaining attached to the posterior and upper part of the cavity, and projecting into the foramen lacerum of the orbit and right nostril, as well as in other directions. The trachea and bronchi contained some frothy blood. Numerous small dark spots of congestion were met with in the lung, resulting from some of the small bronchi being filled with blood.
