CASE.—Private William B. Brock, Co. B, 110th Ohio Volunteers, aged 32 years, was wounded at the battle of Cold Harbor, Virginia, June 3d, 1864, by a conoidal musket ball, which struck about two inches to the left of the median line and anterior to the coronal suture, passed backward along the sagittal suture, fracturing the external table of the left parietal bone, and emerged about two inches from the point of entrance. He was admitted to the hospital of the 3d division, Sixth Corps; on June 7th, was sent to the Lincoln Hospital at Washington; on June 18th, was transferred to the Summit House Hospital, and on October 7th, to the Satterlee Hospital, Philadelphia. The wound had healed, but the patient was nervous and could not bear the heat of the sun; the vision of the right eye was impaired, and the right arm was nearly useless. He was discharged on February 9th, 1865, and pensioned. On September 24th, 1867, Pension Examiner W. S. Parker reported that the wound, which, it seems, resulted in exposing a portion of the brain, was about a year in healing; the patient is unable to bear exposure to the sun or heat, and suffers from vertigo. His disability is rated total and doubtful.
