It has appeared from the calculations of an eminent Physician, that the annual mortality from diseased lungs throughout Great Britain, amounts to one hundred and forty thousand, and that from this class of disorders more than one third expire from Pulmonary Consumption. When we consider the size and peculiar construction of the lungs, their perpetual motion, the chemical process going on in them, and their exposure to the action of contaminated air, or sudden changes in its temperature, it can be no matter of surprise that Pulmonary Complaints are so frequent; and the lungs, not possessing the same natural powers of removing diseased structure, or of mutation as other parts of the body, we may account for their fatal termination from the want of application of proper auxiliaries, as counteractives. Various and contradictory are the opinions of medical men, as to the hectic fever, which is symptomatic of the disorder, being a primary disease, and some absurd notions have been advanced in support of their statements. The recapitulation of these opinions will not, however, interest the afflicted, or casual reader. One proof of the discrepance of their statements on the origin of this disease, must, however, be advanced: Dr. Young considers that, “the want of proper nourishment is the most frequent cause of Consumption.” If so, it may be inquired, how does it happen that the disease most frequently occurs in the families of the opulent? Dr. Lambe, a man of equal experience, fearlessly asserts, “that an excessive use of animal food is among the most prominent and prevalent procuring causes of the disease,” and consequently recommends a vegetable diet. Surely, it may be observed, these contradictory opinions are not likely to increase the confidence of the public in the healing art.
