Those who by their make, or by the disease having in former instances appeared in their family, are predisposed to this complaint, ought to be peculiarly attentive in the article of diet. A spare and cooling regimen is the best. They should avoid violent exercise, and every other exciting cause; and use the precaution of losing blood in the spring. If their circumstances permit, they ought to pass the cold months in a mild climate; but, if they are obliged to remain during the winter in Great Britain, let them wear flannel next the skin, and use every other precaution against catching colds. The fourth cause above enumerated is, tubercles in the lungs. The moist, soggy, and changeable weather, which prevails in Great Britain, renders its inhabitants more liable, than those of milder and more uniform climates, to catarrhs, rheumatisms, pleurisies, and other diseases proceeding from obstructed perspiration. The same cause subjects the inhabitants of Great Britain to obstructions of the glands, scrophulous complaints, and tubercles in the substance of the lungs. The scrophulous disease is more frequent than is generally imagined. For one person in whom it appears by swellings in the glands below the chin, and other external marks, many have the internal glands affected by it. This is well known to those who are accustomed to open dead bodies. On examining the bodies of such as have died of the pulmonary consumption, besides the open ulcers in the lungs, many little hard tumours or tubercles are generally found; some, with matter; others, on being cut open, discover a little blueish spot, of the size of a small lead shot. Here the suppuration, or formation of matter, is just going to begin; and in some the tubercle is perfectly hard, and the colour whitish, throughout its whole substance. Tubercles may remain for a considerable time in the lungs, in this indolent state, without much inconveniency; but, when excited to inflammation by frequent catarrhs, or other irritating causes, matter is formed, they break, and produce an ulcer. Care and attention may prevent tubercles from inflammation, or may prevent _that_ from terminating in the formation of matter; but when matter is actually formed, and the tubercle has become an abscess, no remedy can stop its progress. It must go on till it bursts. If this happens near any of the large air-vessels, immediate suffocation may ensue; but, for the most part, the matter is coughed up.
