CASE 69.—Serg't John Donagan, Co. K, 4th U. S. Inf.; age 27; was admitted Jan. 12, 1865, in the last stages of consumption. The physical signs indicated the affection of both lungs,—metallic tinkling was heard on the right side. He died February 2. Post-mortem examination: The larynx and trachea contained a considerable quantity of purulent liquid. The right lung, forty-eight ounces and a half, was studded with tubercle and had a large cavity in the anterior part of its lower lobe, communicating by an opening with the cavity of the pleura, which contained fourteen ounces of a purulent liquid slightly mixed with blood. The left lung, thirty-eight ounces and a half, had a large cavity in its apex; its lower lobe was studded with miliary tubercle. Both ventricles of the heart and the right auricle contained large, firm, fibrinous clots; the left auricle contained a small quantity of very black fluid blood. The spleen was somewhat softened and weighed twelve ounces. The liver, kidneys and mesenteric glands were normal in appearance.—Act. Ass't Surgeon H. M. Dean, Lincoln Hospital, Washington, D. C.
