CASE 852.—Private J. F. Geer, Co. F, 112th New York, aged 22 years, was wounded at Cold Harbor, June 2, 1864. Surgeon S. A. Richardson, 13th New Hampshire, recorded his admission to the Eighteenth Corps field hospital with "shot wound of left ankle." Surgeon R. B. Bontecou, U. S. V., contributed the following description of the injury and operation in the case, which he performed: "The patient was admitted to Harewood Hospital, Washington, June 15th, suffering from a wound of the left ankle, the ball passing from the inner to the outer surface, opening the joint. On admission the condition of the injured parts and the constitutional state of the patient was good. On June 25th resection of the injured joint was performed by lateral vertical incisions over the malleoli, exposing the articulation. The ends of the tibia and fibula were cut off by the chain saw, and the upper portion of the astragalus​ was removed by the cutting forceps. Sulphuric ether was used. Two days after the operation the patient had slight febrile movement and his pulse was a little accelerated. The treatment was supporting; simple dressings were used. Death occurred on July 24, 1864."
