CASE.—Corporal J. Y. Sehamline, Co. I, 51st Pennsylvania Volunteers, was wounded at the battle of Fredericksburg, Virginia, December 13th, 1862, by a piece of shell, which fractured and depressed the frontal bone to the left of the median line, near the coronal suture. He fell senseless, but consciousness soon returned, when he was conveyed from the field. He was taken to Washington, and entered the Judiciary Square Hospital on the 18th, where coma supervened. During the evening of the same day, several fragments of bone were removed and the depressed portions elevated. No anæsthetic was used. The patient rallied and became partially sensible; strabismus disappeared before morning. On the second day after the operation, his pulse was 76, appetite fair, but the mind rather slow. On the 1st of January, 1863, he was a little giddy and complained of slight headache, but was otherwise improving rapidly. He was transferred to the Invalid Corps on May 17th, 1863. He is not a pensioner.
