The effects of such a morbid structure upon the collier population in general is very marked. Previous to the late legislative act, the tender youth of both sexes were at an early age consigned to the coal pit, and obliged to labour beyond their feeble strength, in circumstances ill adapted to their years. Such early bodily exhaustion soon produced in them a pallid countenance, soft and relaxed muscular fibre, and predisposed much to disease as they advanced in life. The miner on this account was generally from his youth, thin; in fact, you never see a fat and healthy-looking collier, and, according to the advance of pulmonary disease, with them, so is the progress of emaciation. Such a state of body may well be looked for in miners, labouring as they do, from ten to twelve hours in the twenty-four under ground, breathing a heated and impure atmosphere, which with difficulty sustains life, and which is demonstrably calculated, from its deleterious qualities, to induce serious disease. The effects manifest in the parent descend, and visible in the youngest children; they are squalid and wretched-looking,--and how can such offspring be otherwise? They are exceedingly subject to all children's diseases, and peculiarly predisposed to pulmonary irritation of one kind or other. With regard to medical treatment, little can be done after the disease has passed its first stage. Early removal from the occupation, and proper attention to nutrition, alone seem to hold out the hope of prolonging the life of the patient; but if there be carbon lodged in the pulmonary tissues, there is a certainty of its sooner or later proving fatal. Attention to the state of the digestive organs, and using every means to remove the dyspeptic symptoms, which are prominently present throughout the various stages of this disease, are indispensably requisite; and, as to nutrition, the nature of the diet should be as generous as possible. Anodynes and expectorants are the only remedies which seem at all efficacious in allaying irritation. With a view to remove urgent symptoms, venesection has repeatedly been had recourse to, but in almost all instances I would say, with decidedly bad effects. Blood-letting does harm, producing general debility and rapid sinking.[25]
