He was admitted into Stanton Hospital, Washington, on the 20th, where spiculæ of bone were removed. Ice dressings were applied, and tonics and stimulants administered. The patient sank rapidly, and died on May 24th, 1864, from exhaustion. The pathological specimen is No. 2679, Sect. I, A. M. M. A section of cranium, with six fragments of bone. The opening in the parietal measures one and three-fourth inches from right to left, and half an inch antero-posteriorly. The shape of the opening is very unusual, being nearly that of a rectangle.
