_Put an Ounce of that Pouder newly made, into a pretty large Glass, and put to it a Quart of good Sack; Set it in a gentle heat, for three or four Hours, it will take a Tincture: And of this one may take half a Spoonful at a time: And I suppose two Spoonfuls in a convenient_ Vehicle, _may be a good_ Sudorifick _to be given one that is infected_. Though Purging in time of Pestilence is not good, as =Diemerbroek= by frequent Examples has observ'd, yet in _Cachochymick_ Bodies, it may be convenient once in a fortnight, to take a Dose of _Pillulæ Ruffi_; Take half a Dram at Night, and next Morning take the wonted Antidote, as at other times. Also for those that live in an infected Air, that there is suspicion that they may daily take in some pestiferous Vapours, which fermenting with the Blood and Humours, may insensibly at last break out in the =Plague=; it may not be amiss, once or twice a week, to take pretty large =Sweats= in their Beds: And this to be done, especially if the Party has had any occasion whereby he may suspect himself to have been more open to infection, or that he has taken any: After such Sweat he should keep his Chamber the forepart of the day, till the Pores are reduc'd to be as they were before. _To provoke such a Sweat: Take of_ Venice Treacle, _one Dram; dissolve it in three Ounces of_ Carduus _Water, add a Spoonful of_ Syrup _of Pestilential_ Vinegar; _Or take a Draught of Posset-Drink, made with Pestilential_ Vinegar; _In which boyl a few_ Petasitis _Roots: To promote and continue the Sweat, take Posset-Drink with_ Meadow-Sweet, _or else with_ Carduus, _or_ Marigold-Flowers _boyl'd in it_. Besides the daily and constant life of such _Alexipharmacal_ Remedies, there are other Means, which occasionally and sometimes continually should be taken. For in regard we always draw in the Air at our Nostrils and Mouth, these parts should be well guarded with some Antidotes, that may keep out the poysonous Vapours from entring in, and especially as often as upon occasion we are more nearly expos'd to danger of Infection. To this end, some things to smell to, others to be held in the Mouth, chew'd, and swallow'd down, are frequently to be insisted on.
