and so dropping it upon the Teter, I there could see it immediately gather a very thin skin upon the raw flesh, not unlike that which is seen to gather upon Milk over a gentle fire. This skin would have small holes in it, through which a moisture did issue in small drops, which being wip'd away, and the water continued to be dropp'd warm out of the mouth, the holes would diminish, and at last be all quite healed up.
For the Eye-waters, I conceived them more strongly tersive, and clearing the Eyes; and they had a rough smartness, as if they carryed Sand or Gravel into the Eye.
I have known and try'd three or four healing Fountains of late discovery, or of no old fame that I could hear of.
I did once put rich Marle[errata 1] 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 may resume hereafter.
This comes from the same hand as follows;
I formerly mention'd to you, that, if that Pool of Mr. Philip'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:)
