CASE 1866.—Sergeant P. Hogan, Co. L, 3d U. S. Artillery, was wounded at the battle of Gaines's​ Mill, June 27, 1862, and sent to one of the hospital transport steamers on James River. He was admitted to the Union Chapel Hospital, Washington, July 7, 1862, where Acting Assistant Surgeon W. H. Butler recorded: "Gunshot wound of left arm. Patient transferred to Douglas Hospital July 28th." Assistant Surgeon W. Webster, U. S. A., in charge of the hospital, contributed the specimen (FIG. 666), and reported that the patient was discharged from service November 13, 1862, by reason of "gunshot wound." The specimen is described in the Catalogue of the Surgical Section, 1866, p. 601, as "a flattened, distorted round ball perforated by a fragment of bone from the forearm, which it embraces, necrosed." It is a curious specimen, in which the metal, softened by impact, has embraced and carried off what appears to be a fragment of the upper part of the shaft of the ulna, seven-eighths of an inch in length and three-eighths in thickness. The ball, with the enclosed bone fragment, weighs three hundred and seventy grains Troy. This man was a pensioner. He died November 10, 1873. The papers in the case which might afford additional particulars were in use at the Pension Office and could not be consulted.
