A CHAIN of
I N Q^U I R I E S, §te
FOR Introduction to the following piece I assure the reader, that nothing could, in my present situation, have induced me to be at the pains of writing it, but a firm belief that it would prove a valuable present to the public. What entertainment soever the reasoning or notional part may afford the mind, I will venture to fay, the other part seemethi so surely calculated to do good to the body, that both must be gainers. For if the lute be not well tuned, the musician fails of his harmony. And in our present state, the operations of the mind, so far depend on the right tone or good condition of it's instrument, that any thing which greatly contributes to preserve or recover the health of the body, is well worth the attention of the mind. These considerations have moved me to communicate to the public the falutary virtues of tar-water -, to which I thought myself indispenfably obliged, by the duty every man owes to mankind. And, as effects are linked with their causes, my thoughts on this low, but usesul theme led to far
A a «her ther inquiries, and those on to others remote, perhaps, and speculative, but, I hope, not altogether useless of unentertaining.
i.TN certain parts of America, tar-water is .£ made by putting a quart of cold water to a quart of tar, and stirring them well together in a vessel, which' is' left staridirig till the" tar sinks ttf the bottom. A glass of clear water being poured off for a draught is replaced by the fame quantity of frelh water, the vessel being shaken and left to stand as before^ And this is repeated for every glals; so long as the fir cofitinues to impregnate the water sufficiently, which will appear by the smell and taste. But as this method-prodaceth tarwater of disserent degrees of strength, I chuse to make it; in the following manner: Pour a gallon of colcl water on a quart of tar, and stir and mix them thoroughly with a ladle or flat stick for the space of threp or four minutes, after which the vessel must stand eight and forty hours that the tar tsiay have time to subside* when the clear water i* to l?e poured off and kept for use, no more being made from the fame tar, which may still serve for common purposes.
2 This cold infusion of tar hath been used irt some of our colonies, as a preservative or preparative against the small-pox, which foreign practice induce'd me to try. it in my own neighbourhood, when thefmall-pox raged with great violence. And the. trial sully answered my expectation: all those, within my knowledge, who took the tar-water having either escaped that distemper, or had it very favourably. In one family there was a remarkable instance of seven children, who came all very well through the sinall-pox, except one young
