CASE 10. (The subject of the following case is still alive, 1845.) J. S., aged thirty-six. He was born of collier parents, in the parish of Pencaitland, and at as early an age as eight years, went under ground to assist his parents in the transmission of the coal, and when fit for work became a coal-hewer. From his infancy he was rather of a delicate constitution, with flat and contracted chest. When I first saw him, which was about eight years ago, (1837), he was in full employment as a coal-hewer, complaining of shooting pains through his chest, tickling cough in the morning, with scanty tough expectoration, and frequent palpitations. He was repeatedly under treatment for bronchial affection, which was usually relieved by expectorants, blisters, and _continued_ counter-irritants. Each attack of bronchitis was the result, as he expressed it, of "breathing bad air in the pit," in which he was obliged to relinquish labouring, as the lamp would not burn, from the state of the atmosphere. He never wrought at the stone-mining nor blasting. In examining the chest with the ear, at this stage of the affection, the mucous rale was distinctly heard, and exceedingly loud throughout the greater part of the chest. The heart's action was strong, but natural; pulse 70, full and bounding. About four years ago, he removed from Huntlaw to Blindwell, a coal-work towards the sea-coast, an extension of the same coal formation. At this time, 1841, he had very troublesome cough, particularly in bed, scanty frothy expectoration, annoying dyspnoea, preventing him taking sufficient nourishment, headach, obstinate bowels. He continued under all these ailments to labour with much difficulty, till the summer of 1843.[18] In reviewing the morbid appearances in the cases now detailed, it will be observed, that in the majority of them, the left lung exhibited the greater amount of diseased structure. This fact is particularly interesting, as in _tubercular_ phthisis, a similar predominance of disease is found on the left side. In almost all the cases, there was found very extensive effusion into the serous cavities, and particularly into those of the pleura and pericardium. Both pleurae were much thickened, and all the marks of a long standing pleuritic and pericardial inflammatory action were seen. The substance of the heart, in all the cases, was soft and attenuated; the right auricle and ventricle were dilated; and there was thickening of several of the valves. The liver and spleen were usually large and congested. In all the cases, as the disease advanced, the pulse came down to a very unfrequent and thready beat. From the great extent of the venous congestion, the disease often assumed the aspect of asphyxia; and in some instances the colour of the patients resembled that of persons labouring under cyanosis.
