CASE.—Private Jacob Boyer, Co. E, 11th Pennsylvania Volunteers, aged 33 years, was wounded at the battle of Fredericksburg, Virginia, December 13th, 1862. The missile entered just in front and above the external meatus, passed a little upward and inward, and then glanced downward to the mastoid portion of temporal bone, fracturing in its course the external table, and lodging over the mastoid process. He was admitted to the hospital of the 2d division, First Corps, and on December 18th was sent to Harewood Hospital, Washington, where, in January, 1863, a conoidal musket ball was removed through an incision. On January 20th the wound had nearly healed, and on May 6th, 1863, the patient was returned to duty. This soldier was subsequently made a prisoner, and according to the certificate of Assistant Adjutant General S. Breck, died at Salisbury, North Carolina, January 31st, 1865, the cause of death not being stated. In the application for pension by the widow it is stated that he died "by reason of scurvy and diarrhœa."
