and make Injections of the several things most used in Physick into the Veins of Creatures, both in quantities, and into different Veins, as into the Thigh-veins of some Dogs, and Jugalars of some others, and in much lesser quantities of such things as kill suddenly; for in the little time I have spent in these sort of Experiments, I easily perceive notable discoveries might be made thereby: One Dog that lived became Lame and Gouty; another with Quick-Silver died in about Sixteen Weeks time, Consumptive, and I discovered Quick-Silver in the Impostumated parts of his Lungs. _Query_, Whether some Persons that have been Flux'd, or used Quick-silver Oyntments, and the like, and afterwards become consumptive, owe not their Distemper to the abusive use of a most excellent Remedy? Much after the same manner, the subtile Quick-Silver getting into the Mass of Blood by degrees, through its ponderosity settles in the Lobes of the Lungs, and causes Ulcers there. But to return: The Poison of Vipers and Mad Dogs I suppose kill by thickning of the Blood, as many Malignant Fevers, also do; in all which Cases, I look on Volatil Salts to be the properest Physick, as keeping the Blood from congealing. I had a singular Instance hereof in a Gentleman of _Yorkshire_, bit with a Grey-Hound on the _Thursday_, not three Minutes before the Dog died Mad; he bit him in several places of the Hands, as he was giving him a Remedy: The _Monday_ following the Gentleman was very ill, and came to our Town to an Apothecary his Acquaintance, who knowing not what to do, desired my Assistance. When I came, the Gentleman could talk, but every two or three Minutes he had violent Fits, and would tell us when they were over, that his Brains worked like Birm in an Ale-Fat, and seemed to Froth up at every Fit. The Apothecary had no Volatile Salt of Vipers; so I took the Volatile Salt of Amber, and ordered him Ten Grains in Treacle-Water every half hour: He told me every Dose seemed to clear his Brain, and cool it as perfectly, as if a Bason of Cold Water were poured on his Head, but it returned by degrees again: Having then a Volatile Salt by me that Vomits very well, I gave him a Dose thereof, it worked very well, and he was very much better after it: I then ordered him to continue the Volatile Salt of Amber once every four hours, and at each two hours end, that is betwixt, _Spec. Pleres Archonticon and Rue pouder'd ana gr._ 15. whereby he was so well recovered, that within two days he would needs go home, to look after some urgent Affairs, and afterwards found himself so well, that he forgot to return, and perfect the course; and I heard no more of him for half a Year, when I was fetch'd one Morning to him in great hast. He had been abroad, play'd the Good-Fellow, and in his return home, having rode a great days Journey, being weary, and I suppose finding himself indisposed, he staid all Night in our Town, it being fortunately in his way.
