ARTICLE I.- Osteo-Sarcoma of the Lower Jaw, of immense size, successfully removed. By GEORGE C. BLACKMAN, M.D., Professor of Surgery in the Medical College of Ohio, Surgeon to the Commercial, St. John's, and St. Mary's Hospitals, Cincinnati. On the 2d of July, 1859, Lemuel Hinedon, a negro, aged 30, was admitted into St. John's Hospital for the removal of the lower jaw, which was affected throughout a considerable extent with the disease known as osteo-sarcoma. The magnitude of the tumor caused him to present a frightful aspect. From the history of the case as recorded by Dr. John A. Billings, then resident physician at St. John's Hospital, it appears that nine years before one of the molar teeth on the right side of the lower jaw became loose, and was somewhat painful. Soon after he noticed a small tumor on the bone, which, however, gave him no uneasiness. It increased slowly but steadily up to the time of his admission. In some parts the tumor was quite hard, in others it had an elastic feel, imparting even the sensation of indistinct fluctuation. Deglutition and respiration not seriously disturbed, although the power of mastication was nearly lost. On the buccal aspect of the tumor were two small ulcerated patches, through which, he stated, from time to time he had lost large quantities of blood. Just previous to his admission his strength had been reduced by an alarming attack of hæmorrhage. The appearance of the patient is well represented in Plate I., fig. 1, fig. 2.
