in short, to what physicians call the six non-naturals. We see, on the other hand, that they are not well, whenever they attempt to change their way of living for that of another. Custom, which is a second nature, can never be altered without danger, even in trifling things, though the change be from worse to better. If any alteration was to be made in a healthy man's way of living, under the notion of improving his health, this ought to be tried at any other time rather than at the eve of inoculation. The good expected is uncertain; the ill that may ensue, though at another time of no great consequence, might at this prove very pernicious.
Were it even certain that any change or positive preparation, would be attended with an encrease of health, still this advantage ought to be balanced with the hazard arising from the dread which this previous process often occasions; and of what consequence this may be, will appear in the sequel of this work.
If, after a serious perusal of these considerations, any inoculator will attempt to give rules for a health-encreasing preparation; if he chuses to prescribe a diet, or to order medicines; his preparation will probably bring on a more considerable disorder than would otherwise have appeared; and some of his patients will deserve the epitaph,
