CASE.—Sergeant George Saunders, Co. D, 7th New York Heavy Artillery, aged 39 years, was wounded at the battle of Cold Harbor, Virginia, June 3d, 1864, by a conoidal ball, which entered the back of the head a little above the occipital protuberance, and to the right of the median line, comminuted the bone at the orifice of entrance and lodged in the cranium. He was conveyed to Washington, entering Emory Hospital on June 7th, whence he was transferred to Baltimore on the 11th, and admitted to Camden Street Hospital. On June 16th, he was placed under the influence of chloroform, and Surgeon Z. E. Bliss, U. S. V., removed a number of loose fragments of bone, and with a probe traced the track of the ball through the substance of the brain, in a forward and upward direction about four inches, but failed to discover the ball. Some pus escaped as the probe was introduced. The parts were very little swollen and not very painful. The patient reacted promptly. Interrupted sutures were inserted, adhesive strips and cold water dressings applied, opiates administered, and stimulants and nutritious diet ordered. There was no apparent change in the patient s condition after the operation. Coma supervened, and death occurred June 18th, 1864.
