CASE.—Private J. L——, Co. A. 122d Ohio Volunteers, aged 23 years, was wounded at the battle of Mine Run, Virginia, November 27th, 1863, by a conoidal ball, which entered the frontal bone, just above the inner canthus of the right eye, passed downward and inward, and made its exit through the outer wall of the left antrum of Highmore. He was treated in a field hospital for several days, and on December 4th, admitted to the 3d division hospital at Alexandria, Virginia. His condition had been good, but he soon became comatose. On December 8th, Surgeon E. Bentley, U. S. V., applied the trephine and removed a disk of bone from the centre of the frontal bone between the superciliary ridges. Splinters of bone, constituting nearly all the nasal and left malar bones, were removed at the same time. No relief was afforded, and the patient died on December 13th, 1863. The pathological specimen, which shows a section of skull trephined for extensive fracture of frontal and facial bones, together with the history, was contributed by the operator.
