I did once put rich Marle for some days in a vessel of water, to try whether the water would acquire a healing vertue, but my Experiments were interrupted. I had in my thoughts many other ways of Tryal; which I may resume hereafter.
A farther Accompt of the Vitriolate-water, mention'd Num. 18 p. [323]. Together with some other particulars touching waters.
This comes from the same hand as follows;
I formerly mentioned to you, that, if that Pool of Mr. Phillip's, which seems to be of Vitriolate-water, were on my ground, I would drain it, and search the head of the Spring, pursuing the source, till I could well discern, through what lay of Earth or Gravel it does pass. Now I shall tell you, that I have taken order for the further tryal of the said Water, by boiling a greater quantity in a Furnace, &c. But just as we were in readiness for the tryal, a stream of Rain-water fell into the Pool, and so discourag'd us for the present. I have also taken a course to turn the falling Waters aside, and to drain the Pool, that we may see, what the Native Springs (whether one or more) may be. Of which more hereafter.
I wish (so he goes on) we had a full Accompt of our Salt-Springs at Droyt-wych near Worcester, and at Nant-wych in Cheshire (what other Salt-Springs we have in England, I know not:)
It should be inquired, at what distance they are from the Seas, or from Salt-fluxes, from Hills, and how deep in the Vales? What the weight? Whether in droughts or long Frosts the proportion of Salt or weight increaseth? Whether the Earth near the Springs, or in their passage hath any peculiar ferment, or produceth a blackishness, if it rests, after it is well drained.
Inquiries for Turky.
Though many Relations and Descriptions of Turky be extant in Print, yet they leave in many a desire of a fuller information in the following particulars, lately drawn up, for the most part by Mr. H. and recommended to an Ingenious Gentleman, bound for that Country; and desired also to be taken notice of by others, that may have occasion to visit the same.
