TO this may be added, that many common Medicines were publickly Sold, which by their extraordinary Heat and Disposition to inflame the Blood, could never be fit for every Age, Sex, and Constitution indifferently, and therefore in many Cases must undoubtedly do Harm. On this Account not only the _Sacred Art_, but the _Publick Health_ also suffered; yet we who were particularly employed in this Affair as Physicians, used all Sollicitations with the Magistracy to restrain such Practices, in Order to stop the Ruin they aggravated. Hence notwithstanding it was made a Question, whether in a Plague, where so many Physicians retire, (not so much for their own Preservation, as the Service of those whom they attend) it is not expedient for every one, according to his Abilities, to do his utmost in averting the common Ruin? In the same Manner as in a Fire all Hands are required, even of the Croud as well as Workmen, to extinguish it. BUT in this Case my own Opinion is determined: In the Restauration of Health, a Person must proceed with more Caution and Deliberation than in the supposed Case of a Fire; for there are Difficulties occur in the Practice of Medicine which are insuperable but by the unlearned; and the fine Texture of a humane Body is not to be managed by as clumsie Hands as the Materials of a House; in the former, if a Person makes a Mistake, it is with great Difficulty repaired; and therefore upon a serious Consideration of the whole Affair, I cannot make any Doubt, but that it is much better even to want Physicians in such Calamities, than to have the Sick under the Care and Management of the unlearned; for such Persons, like those who fight blindfold, know not in what Parts to attack the Enemy, nor with what Weapons to do it; besides which, they also are in Hazard of obstructing these Efforts of Nature, which would many Times, without Help, if not thus hindred, get the better of the Distemper. NOR in this Account are we to neglect, that the Contagion spread its Cruelties into the neighbouring Countries; for the Citizens, which crowded in Multitudes into the adjacent Towns, carried the Infection along with them, where it raged with equal Fury; so that the Plague, which at first crept from one Street to another, now reigned over whole Counties, leaving hardly any Place free from its Insults; and the Towns upon the _Thames_ were more severely handled, not perhaps from a great Moisture in the Air from thence, but from the tainted Goods rather that were carried upon it: Moreover, some Cities and Towns, of the most advantageous Situation for a wholsome Air, did notwithstanding feel the common Ruine. Such was the Rise, and such the Progress, of this cruel Destroyer, which first began at _London_.
