CASE 428.—Private O. H. Dorr, Co. G, 66th Ohio, was wounded at Cedar Mountain, August 9, 1862, by a musket ball, which entered to the right of the ensiform cartilage and emerged near the angle of the ninth rib. He entered Fairfax Street Hospital, at Alexandria, on August 12th. Upon examination, it was thought the pulmonary organs had escaped injury. There was at no time hæmoptysis. The general condition was favorable until August 28th, when there was a chill, followed by severe coughing, the expectoration being purulent and mixed with bilious matter. This form of expectoration continued until the patient's death, September 8, 1862. At the autopsy, it was found that the ball had passed through the lower lobe of the right lung, the diaphragm, and had grooved the convex surface of the liver.
