![Hospital, in which the breathing of one lung had been sup- pressed, and the pleura of that side was conjectured to be filled with solid substance, its cavity was found occupied by strata of coagulum, which had been deposited at dif- ferent times from blood that had flowed from an intercostal artery ulcerated over a rough and carious rib. Hydrothorax, like ascites, is rather an effect of disease, than a disease itself: it commonly results either from some obstruction to the circulation, or from attenuated blood and vascular atony. The symptoms are dyspnoea, orthopnoea, livid countenance^ dulness of the chest on percussion. Malignant disease. In a preparation presented by Dr. Chalmers, of Croydon, in which the lungs were the seat of fungus haematodes, both the pleurae costalis and pulmonalis had given origin to masses of medullary sarcoma. [//. 100.] In a patient who died in the Middlesex Hospital of can- cer of the breast, the pleurse pulmonalis and refiexa were studded with smooth, firm, white, circular, convex tuber- cles, from a line to half an inch in diameter, [u. 101. 102.] SECTION II. The Lungs. Under the head of affections of the lungs, it is convenient to include those of the filamentous texture of the lunos, of the air-vessels, and of the smaller air tubes. Hypertrophy, atrophy, pneumonia, gangrene, pulmonary hemorrhage, oedema of the lungs, emphysema, phthisis, malignant tu- mours, hydatids of the lungs, are the subjects treated of in the present section. I. Hypertrophy. When one lung is destroyed by disease, the other becomes hypertrophied, or grows, to serve its doubled function. The lung increasing in volume becomes firmer, more elastic, and more compact. In place of col- lapsing, when the chest is laid open, it sometimes pro- trudes from it, as if the space that contained it had been too small.](https://iiif.wellcomecollection.org/image/b21066735_0529.jp2/full/800%2C/0/default.jpg)
