My valuable friend, Dr. Walker, of Leeds, in Yorkshire, has noticed, in several parts of that extensive and commercial county, and particularly in Leeds; that, “since the more plentiful introduction of Tea into the families of the industrious poor, by the late reduction of its price, the Atrophia Lactantium, or Tabes Nutricum, a species of decline, has made an unusually rapid progress. The difficulty with which animal food is procured by the lower ranks of society, in quantity sufficient for daily nutriment, has led many of them to substitute, in the place of more wholesome provisions, a cheap infusion of this foreign vegetable, whose grateful flavour (and perhaps narcotic quality, which it possesses in a small degree in common with most other ever-greens) is found to create an appetite for itself, in preference to all other kinds of aliment that the scanty income of poverty allows these deluded objects to procure; though I am sorry to have occasion to add, that the lowering effects of tea-drinking lead too many of these to seek relief from spirits, and other pernicious cordials, at the expence of health, and the sure consequences of penury and want. “As this change, in the article of diet, has been very generally made, especially by the females, and the younger branches of the families of the manufacturing poor, their constitutions have been rendered much less able to bear evacuations of any sort, and particularly that of lactation. I may, with great truth, aver, that more than two hundred patients of this denomination have, within the last two years, come under my notice: upon their application for relief, and the consequent enquiry which I have been led to make respecting the nature of their diet, their almost invariable reply has been, that they have chiefly depended upon Tea for their support, at the same time that they were permitting an apparently healthy child to draw the whole of its nourishment from them. “That it is debility, and an impoverished state of the whole system, arising from a deficiency in the due supply of proper and sufficiently nutritious aliment, at a time when the constitution particularly requires it, in consequence of the continual waste which the mother sustains from the suckling of her infant, which lay the foundation of this disease, and that the lungs are but secondarily or symptomatically affected, is clearly evinced from an attention to the symptoms.
