7th.-Feels much better; gums sore. Cont. Pulv. l2th.-Says he is getting stronger every day. l9th.-Is so much improved that he thinks of going out of the hospital. Previous to his so doing his chest was examined. The dulness formerly noticed had disappeared in front, but the right lower back was still less resonant than the left ; the respiratory murmurs were now audible, though more feeble, on the right than oni the left side, especially at the lower and back part of the lungs; a deep inspiration produced a kind of crumpling sound over the seat of the injury. Expansion the same on botlh sides. General health good. Renzarks.-It is not improbable that in this case there occurred a laccration and rupture of one or more vessels, giving rise to an effusion of blood into the cavity of the pleura, and thus producing the plhysical phenomena mentioned as having been detected in the neighbourhood of the injured parti It is not likely that the effusion could have been very considerable, since little more than seven weeks were necessary to allow of the chest recovering its sonoriety and healthy play. Fortunately there appears to have been no in.ammatory complication, as might not unreasonably have been anticipated under the circumstances, and Fwith the exception of the alarming collapse which took place on the night of his admission, and which was in all probability the result of the escape of the blood into the pleural cavitv, the recovery took place without any untoward symptom.
