CASE.—Sergeant William McKenzie, Co. D, 4th Michigan Volunteers, aged 30 years, was wounded at the Wilderness, on May 5th, 1864, by a conoidal ball, which fractured the right external angular process of the frontal bone. He was conveyed to Washington, and admitted, on the 11th, into the Stanton Hospital; thence was transferred, on the 18th, to the Satterlee Hospital at Philadelphia. The sight of the eye was partially destroyed. The case progressed favorably, though there was a slight discharge from the wound. On examination, the ball was found lodged in the bone, and on the 16th of June, the opening was enlarged and the missile, firmly imbedded in the orbital ridge, extracted. The patient recovered rapidly, and on August 3d, 1864, was transferred to Adrian, Michigan, to be mustered out, his term of service having expired. A communication from the Commissioner of Pensions, dated December 8th, 1869, states the patient has nearly lost the sight of his right eye and suffers from hemicrania, owing to which he receives a pension, his disability being rated five-eighths and permanent.
