Case from the case-book and medical descriptive lists of the HAREWOOD HOSPITAL, Washington, D. C., Surgeon Thomas Antisell, U. S. V., in charge from October, 1862, to September, 1863:

CASE 271.—Private Michael McMahon, company I, 105th New York volunteers; admitted November 11, 1862. Chronic diarrhœa. Died, November 15th. Autopsy: The lungs were healthy. The pericardium contained two ounces of fluid. The heart was somewhat enlarged; its ventricles filled with dark coagula. The liver was normal. The spleen much enlarged, congested, and softened. The stomach was large and inflated; its mucous membrane covered with a pseudomembrane the color of bile. The small intestine was normal in its upper part, somewhat congested in the lower part; just above the ileocæcal valve were two ulcers, five inches long and six lines wide, which had nearly perforated the gut. The large intestine was thickened, ulcerated, and covered with dark-colored false membrane, but the ulcers appeared to be cicatrizing. The rectum was in a similar condition to the colon, but even more diseased.
