A Youth was seized with a great Difficulty of Breathing, and the Arteries hardly beat, and, in short, all Things seem’d to bespeak him in his last Moments; I prescribed him ʒ i. of the forementioned Spirits in ℥ iij. of _compound Scordium Water_; but the Symptoms continuing obstinate, I again repeated the same in three Hours Time with Addition of ℈ i. more; and five Blisters were also forthwith applied, after which in about half an Hour, he began to move his Limbs, and recollect himself, as if risen from the Dead: but at last when all Things were hopeful, there appeared a Discolouration upon one of his Legs, where a Blister had been raised, with a Loss of Sense very near to a Sphacelation; upon this the affected Part was deeply scarified and then fomented, which, with a Repetition of the same Draught twice in a Day, by the Blessing of Heaven, again restored every Thing into a hopeful Way. For this Spirit is of such a fiery Nature, that it immediately disperses through the whole Body; and on Account of its great Volatility, helps to encounter with, and correct the saline, malignant Quality of the Pestilence: But I need say no more than that it is the most powerful _Diaphoretick_ that can be given in any Disease whatsoever. WHENSOEVER Things are brought to Extremity, some have Recourse to Mineral Preparations, in Order to drive out the Pestilence by mere Force; amongst which the chief are _Mineral Bezoar_, _Sulphur Auratum_, and _Aurum Vitæ_, &c. the Preparations of which are to be met with in chymical Writers. I am fearful indeed of being too prolix in the Enumeration of Remedies under this Class; although I am very sensible that some _Simples_ prudently chosen may singly encounter a Pestilence with Success, as well as some other Diseases: But because this Evil is usually attended with so many Complications, the Contrivances to oppose it should also, in the Opinion of some, be equally and proportionably complicated; and all Forces drawn up in Battle against it with full Front, in Order to be equal to the Encounter. To this Purpose some of the Sons of _Esculapius_ have invented manifold Compositions; and some of them so prolix, as if they intended a Sacrifice of an _Hecatomb_ to appease the Severity of this tyrannical Destroyer. IT would be entirely foreign to our Business here, to extract all the Medicines which some Writers abound with for this End; and it is our Business here only to take Notice of those which were made Use of with Success in the late Sickness; and in this Performance both Gratitude and Duty oblige me to begin with such as were ordered by the _College_, amongst which first occurs their _Plague-water_.
