CASE.—Private John H. Wingert, Co. E, 14th Indiana Volunteers, received a depressed fracture of the frontal bone at the battle of Fredericksburg, December 13th, 1862. The missile produced an opening two and a quarter inches in length and three-fourths of an inch in width, extending from the inner angle of the right eye upward and outward. He was sent to the hospital of the 3d division, Second Corps, and on December 18th was admitted to Harewood Hospital, Washington. The dura mater was found lacerated, but no fragments of bone were in the wound. Inflammation of the brain and its membranes existed, and the surrounding integuments presented an erysipelatous appearance. The pulse was one hundred and twenty and bowels costive. No paralysis existed, and the patient answered questions correctly. On December 19th stupor supervened, muttering delirium followed, and death occurred December 20th, 1862. On removing the calvaria​, the anterior half of the dura mater was found thickened, and the superior portion of the anterior lobe of right hemisphere was completely disorganised. The ventricles were filled with a sanguineous fluid, and the corpus callosum was softened. The skull-cap was fissured.
