BUT to be yet more particular about these Fumigations, both to mend the Air, and refresh the Houses that have been infected, they must be composed of such Things as raise and comfort the Spirits that were languishing, with their grateful Flavours; for refreshing Smells are a kind of natural _Pabulum_ to the animal Spirits; or they should be of such Substances as by their gummy Viscidity entangle and cover the venomous _Spicula_, so that they cannot act; or, lastly, of such Things as breath out such nitrous Steams, which will either preserve our Bodies from receiving Impurities, or change the Nature of the infectious Particles. I do not indeed deny, but some ungrateful Smells may be sometimes more convenient than sweet ones, as they fix those Spirits which would otherwise exhale; and a copious Efflux of saline Particles will often keep them from Infection and Injury. But to reduce these into Classes. The _Simples_ of the first Class are _Musk_, _Civet_, _Amomum_, _Lavender_, _Rosemary_, _Roses_, _Angelica_, _Marjoram_, _Cloves_, _Rhodium Wood_, _Aloes Wood_, &c. Of the second, _Frankincense_, _Benjamin_, _Storax_, _Bdellium_, _Labdanum_, _Pitch_, _Sagapenum_, _Myrrh_, &c. Of the third Class, _Sulphur_ and _Nitre_, more of which hereafter. BUT further, that all the Means of propagating the Plague may be removed, it is very wisely ordered by the Magistracy, to kill all Dogs, Cats, and other domestick Brutes, lest these Creatures in their Passage from one Place to another should carry along with them the pestilential Infection. YET although both the Makers and Executors of the Laws were very diligent in their Duty during the late Sickness, the Contagion notwithstanding spread; when therefore all the Care and Skill of the Magistrate could avail nothing in stopping the common Destroyer, the utmost Application was made to preserve the Individuals under its Visitation: For which Purpose, first of all were removed all Means of rendering our Bodies more subject to take the Infection, and the best Care taken to fortifie the Constitution against its Attacks, and to support it under its Tyranny. I know not indeed a greater Neglect than in not keeping the Body clean, and keeping at a Distance every Thing superfluous or offensive; and during the pestilential Constitution nothing was worse than Evacuations of all Kinds: But if a _Plethora_ required _Phlebotomy_, the Blood should be taken away by a small Orifice, in but little Quantity, and at several Times: A Person loaded with bad Humours, should be discharged of them, if possible, immediately; if they glut the Stomach, and first Passages, they ought to be thrown off by Vomiting, Drinking in the Operation good Quantities of Posset-Drink, in which hath been boiled the Leaves of _Carduus_ and _Scordium_; and also the Bowels should be cleansed, to which Purpose the following is useful:
