The regard I have always had, and shall still have for the Reputation and Memory of my dear _Master_, and best _Friend_, will not, I presume, be thought to lessen, by my giving way upon these terms to this Publication; since it is so earnestly desir'd, and so well esteem'd of: And the Good that is aim'd at by it can be no ill Apology for _Thy Friend and Servant_, _J. Hemming_. _St._ Martins-Lane, Sept. 1. 1690. A Plain and Easie METHOD, _&c._ In time of =Pestilence=, because a Physician cannot easily, or often, be consulted with; Therefore it behoveth all Persons, as well Poor as Rich, to be furnish'd with Remedies against that Contagious Disease; and certain Rules, or a Method how to use them: Which Method being very plain, and almost the same to all People, consists chiefly in these two Parts, _viz._ =How to preserve the Whole from taking Infection; And how to cure the Sick that are infected=. Touching the First; Though the surest way is to fly from it, yet in regard this cannot be done by all, some Means should be us'd to secure [so far as it is possible] those that are forced to stay by it. Such Means of =Prevention=, either concern the Publick Magistrate, which are already sufficiently known, and commonly practis'd in all places that are infected, and it would be superfluous to repeat them here; Or else such as belong to private Persons, what ways every Man that lives in, or near an infected place, may arm himself against the danger of Contagion; Which should be endeavour'd, as well by purifying the Air we breathe, as also by fortifying our selves against taking the Infection at our Nostrils, Mouth, or Pores of the Body, which are the chiefest, if not the only parts the Poison creeps in at. That the =Air= we breathe in may be wholesome, all Things, that may advance or add to the corruption of it, should diligently be removed; our Houses, and Streets kept clean; all Filth, and whatever may cause noisom smells, be taken away; and amongst other things, the smell of Sope Suds, and Lye, in the washing of Clothes, be avoided; this, Experience has taught to be very dangerous; as 'tis observed by =Diemerbroek= and =Vander Heyden=. Besides the suppressing of Vapours that may increase the infection of the =Air=, it is to be purg'd of that Malignity it brings with it from other infected places; and this is done by great Fires, which should be continually kept, except the Weather be too hot, and by Fumes of _Sulphur_, _Nitre_, _Frankincense_, _Pitch_, _Rosin_, _Tarr_, and the like, which every day should be burnt in the Room we most frequent, also before our Doors, and on the tops of our Houses. Of simple Medicines to be us'd for this purpose, _Brimstone_ is commended for the best that is; 'Tis likely that _Vitriol_, which partakes much of the like acid Spirit, may be very proper; but in regard 'tis not easily combustible, make this mixture, and strew of it on Coals in a hot Chafing-dish.
