says my friend, “let all the prescriptions of all the physicians in London be examined, and it will be found that they are all compounded of the same things, with such variations only as the particular fancy of the doctor leads him to; so that,” says he, “every man, judging a little of his own constitution and manner of his living, and circumstances of his being infected, may direct his own medicines out of the ordinary drugs and preparations.  Only that,” says he, “some recommend one thing as most sovereign, and some another.  Some,” says he, “think that Pill.  Ruff., which is called itself the antipestilential pill, is the best preparation that can be made; others think that Venice treacle[341] is sufficient of itself to resist the contagion; and I,” says he, “think as both these think, viz., that the first is good to take beforehand to prevent it, and the last, if touched, to expel it.”  According to this opinion, I several times took Venice treacle, and a sound sweat upon it, and thought myself as well fortified against the infection as any one could be fortified by the power of physic.

As for quackery and mountebank, of which the town was so full, I listened to none of them, and observed often since, with some wonder, that for two years after the plague I scarcely ever heard one of them about the town.  Some fancied they were all swept away in the infection to a man, and were for calling it a particular mark of God’s vengeance upon them for leading the poor people into the pit of destruction merely for the lucre of a little money they got by them; but I cannot go that length, neither.  That abundance of them died is certain (many of them came within the reach of my own knowledge); but that all of them were swept off, I much question.  I believe, rather, they fled into the country, and tried their practices upon the people there, who were in apprehension of the infection before it came among them.

This, however, is certain, not a man of them appeared for a great while in or about London.  There were indeed several doctors who published bills recommending their several physical preparations for cleansing the body, as they call it, after the plague, and needful, as they said, for such people to take who had been visited and had been cured; whereas, I must own, I believe that it was the opinion of the most eminent physicians of that time, that the plague was itself a sufficient purge, and that those who escaped the infection needed no physic to cleanse their bodies of any other things (the running sores, the tumors, etc., which were broken and kept open by the direction of the physicians, having sufficiently cleansed them); and that all other distempers, and causes of distempers, were effectually carried off that way.  And as the physicians gave this as their opinion wherever they came, the quacks got little business.
