[3] Although this hurricane, in itself and its consequences, was so destructive to the lives and health of men, yet, with regard to the inhabitants on shore, it had a surprising and unexpected effect in mending their health. I wrote an account of this hurricane to the late Dr. Hunter, who communicated it to the Royal Society, and the following passage is extracted from it: “The consequences of this general tumult of nature, on the health of man, was none of the least curious of its effects. I made much inquiry on this head, not only of the medical gentlemen who had the charge of hospitals, and of the physicians of the country, but of the inhabitants, and every one had some cure to relate either of themselves or their neighbours, in a variety of diseases. Nor could I find that either those who were in health, or those who were ill of any disease whatever suffered from it, otherwise than by its mechanical violence; but, on the contrary, that there was a general amendment of health. This is a fact, which I could neither credit, nor would venture to relate, were it not supported by so many concurring testimonies. It had a visible good effect on the acute diseases of the climate. The chronic fluxes, of which there were then some at the naval hospital, were cured or much relieved by it. But the diseases upon which it had most evident and sensible effects, were pulmonic consumptions. Some recent cases of phthisis, and even the acute state of pleurisy, was cured by it; and in the advanced and incurable state of it, the hectic fever was removed, and remarkable temporary relief afforded. A delicate lady of my acquaintance, who was ill of a pleurisy at the time, and passed more than ten hours in the open air, sitting generally several inches deep in water, found herself free of complaint next day; had no return of it; and when I saw her a few weeks after, was in much better health and looks then usual. The people observed that they had remarkably keen appetites for some time after, and the surviving part of them became uncommonly healthy; some of both sexes, whom I had left fallow and thin a few months before, looking now fresh and plump. It is very difficult to account for this, as well as every thing else in the animal œconomy; but it was probably owing in part, at least, to the very great coldness and purity of the air from the upper regions of the atmosphere. Great agitation of mind sometimes also produces a revolution in health; and we know that the effect of external impressions in general is very different when the mind is vacant, from what it is when occupied and interested by objects, whether of pleasure and satisfaction, or of danger and suffering.” [4] In order to ascertain more exactly the degree of sickness in each month, a column was afterwards added to the form of the returns, expressing the number taken ill of the several diseases in the course of the month.
