CASE 6. D. L., aged twenty-six years at his death, in August 1837. He was the son of a collier, at Pencaitland, and engaged at an early age in putting the coals to his father; and when he was fit for full collier-work, in 1831, he was employed at the same coal-work. He was a tall, well-formed, robust young man, and not at all liable to chest affection. For some time he wrought, as a coal-hewer, but latterly was induced, (1834), for higher wages, to become a stone-miner in the same coal-pit, where gunpowder was used extensively in the operations. About six months after he commenced stone-mining, he became affected with a short tickling cough, expectoration of pearly tenacious phlegm, hurried breathing, tightness across the chest, frequent pulse (95), heat of skin during the night, and occasional throbbing in the head. Being young, and fearless of any danger from the occupation, although warned of the consequences, he continued to prosecute it, and twelve months (May 1835) after he first began, the cough had increased much in severity. The expectoration was diminished, and had become more difficult to void from the bronchi, and the breathing was more oppressive, accompanied by a painful tightness across the chest in the morning. The body was considerably reduced in bulk to what it previously had been. The pulse ranged from 80 to 90; the appetite was impaired, and there was in the morning a tendency to retching. The nocturnal heat of skin continued, without any moisture, though his body was drenched with a clammy sweat during the hours of labour. The respiratory murmur was harsh and extensive at the upper part of both lungs, while the sibilant ronchus was heard occasionally in the lower lobes. The heart's action was regular, but impulse strong, on applying the hand to the cardiac region. The remedies resorted to were blisters, bleeding (at an early stage), expectorants, and tonics, which, to a certain degree, relieved the more urgent symptoms.
