CASE.—Sergeant Alexander E——, Co. B, 56th North Carolina Regiment, aged 30 years, was wounded at Petersburg, March 28th, 1865, by a conoidal ball, which entered the body of the left malar bone, producing a comminuted fracture, passed from left to right through the orbit, fracturing the ethmoid bone, and lodged in the anterior portion of the base of brain on the right side. He was conveyed to a field hospital, and on March 30th was admitted to Lincoln Hospital, Washington, being nearly comatose. The probe could be passed into the brain. Death occurred on April 2d, 1865, from exhaustion and congestion. The autopsy revealed the course of the ball as above stated. The pathological specimen is No. 85, Sect. I, A. M. M., and consists of nine fragments, chiefly from the malar bones, and the ball, separated into two parts. The specimen, with the history, was contributed by Acting Assistant Surgeon T. P. Arthur.
