![The other occasional attendant is the yellow jelly-like matter, the infiltration tuberculeuse, gelatiniforme/' of Laennec; who believes it to be only a more liquid state of the tuberculous matter poured into the parenchyma of the lungs. The ordinary situation of tubercle is the upper part of the lungs; and the left lung is more commonly affected than the right. I must refer the reader to Dr. Clark's scientific and prac- tical Treatise on Consumption, for an account of the progress and symptoms of the disease, to which tubercles in the lungs give rise;—from the first period, when a slight diminution of strength, a pulse easily excited, occasional flushings, imper- fect rest, slight but frequent cough, irritable mucous mem- brane of the bowels, first awake suspicion : and when on examining the chest, one side may sound duller on percussion than the other, and the voice may be more resonant on that side.—To the second period, when the figure has become ema- ciated, the cough more frequent, the frothy fluid which had been before expectorated colourless, now containing small specks of opaque curdy matter, of a pale yellowish colour, sometimes streaked with blood; the respiration hurried, the pulse frequent, with afternoon flushes and night sweats; the sound on percussion duller; crepitant rhoncus heard, and bronchophony; or even in one or more points of the clavi- cular, or scapular regions, pectoriloquy.—To the concluding stage, in which to an aggravation of the previous symptoms, dyspnoea threatening suffocation, distressing muscular pains about the chest, colliquative diarrhoea, close the scene. IX. Cysts, hydatids, and phosphate of lime-deposit, are met with in the lungs. X. Mediillaiy sarcoma and mela)ioma, separately or toge- ther, are liable to form in masses in the lungs. In ,the case from which the specimen [ii. 86.] was obtained, the only pulmonary symptom was frequent haemoptysis. The lung is studded with sjtherical masses of medullary sar- coma. 2 L](https://iiif.wellcomecollection.org/image/b21066735_0541.jp2/full/800%2C/0/default.jpg)
