But three cups of strong tea will now make my hand shake, so that I can hardly write. And let any try the experiment: If any tea make his hand shake, it will not be weak tea, but strong. This has exceedingly increased the number of nervous complaints throughout the three kingdoms. And this furnishes us with a satisfactory answer to the common question, “Why are these complaints so general now, which were scarce heard of two or three centuries ago?” For this plain reason: Two or three centuries ago, no tea was drank in either Britain or Ireland. 5. But allowing both tea and spirituous liquors to have contributed largely to the increase of nervous disorders, yet it may be doubted, whether one or both of them are the principal causes of them. The principal causes of them ‘(particularly among those who do not work for their living) are, as Dr. Cadogan justly observes, indolence, intemperance, and irregular passions. First. Indolence, the not using such a degree of exercise as the constitution requires. To illustrate this: Our body is composed of earth, water, air, and fire; and the two latter are as necessary as the two former. To supply these, that curious engine, the lungs, continually takes in the air; to every particle of which a particle of fire is attached, which, being detached from it, is mingled with the blood. Now, exercise quickens the motion of the lungs, and enables them to collect from the air a due quantity of fire. The nerves are the conductors of this ethereal fire, vulgarly called the animal spirits. If this is duly diffused through the whole body, we are lively and vigorous; if it is not, (which without exercise it cannot be,) we soon grow faint and languid. And if other disorders do not ensue, those termed nervous surely will, with that whole train of symptoms which are usually comprised in what is termed lowness of spirits. 6. Intemperance is another principal cause of this;--if not intemperance in drink, which is not quite so common, yet intemperance in meat; the taking more of it than nature requires. Dr. Cheyne well observes, it is not generally the quality, but the quantity, of what we eat which hurts us.
