Notwithstanding, for a more manifest, and fuller tryall hereof, put as much powder of galls, as will lye on two-pence, or three-pence, into a glasse full of this water newly taken up at the fountaine, you shall see it by and by turned into the right and perfect colour of Claret wine, that is fully ripe, cleare, and well fined, which may easily deceive the eye of the skilfullest Vintner.
This demonstration hath beene often made, not without the admiration of those, who first did see it. For the same quantity of galles mingled with so much common water, or any other fountaine water thereabouts, will not alter it any thing at all; unlesse to these you also adde Vitrioll, and then the colour will appeare to be of a blewish violet, somewhat inkish, not reddish, as in the former, which hath an exquisite and accurate conjunction of other minerall exhalations, besides the vitrioline. But this probation will not hold, if so be you make triall with the said water being caried farre from the well; by reason of the present dissipation of his spirits.
CHAP. 9.
Of the properties, and effects of Vitrioll, according to the ancient and moderne Writers.
The qualities of Vitrioll, according to Dioscorides, Galen, Ætius, Paulus Ægineta, and Oribasius, are to heate and dry, to bind, to resist putrefaction, to give strength and vigour to the interiour parts, to kill the flat wormes of the belly, to remedy venemous mushromes, to preserve flesh over moyst from corruption, consuming the moysture thereof by its heat, and constipating by his astriction the substance of it, and pressing forth the serous humidity.
And according to Matthiolus in his Commentaries upon Dioscorides, it is very profitable against the plague and pestilence, and the chymicall oyle thereof is very availeable (as himselfe affirmeth to have sufficiently proved) against the stone and stopping of urine, and many other outward maladies and diseases, (Andernæus and Gesner adde to these the Apoplexy) all which, for avoyding of prolixity, I doe here purposely omit.
Neither will I further trouble the Reader with the recitall of divers and sundry excellent remedies, and medicines, found out and made of it in these latter times, by the Spagyricke Physitians, and others: In so much that Joseph Quercetanus, one of those, is verily of opinion, that out of this one individuall minerall, well and exquisitely prepared, there might be made all manner of remedies and medicines sufficient for the storing and furnishing of a whole Apothecaries shop.
But it will (perhaps) be objected by some one or other in this manner: If vitrioll, which as most doe hold, is hote and dry in the third degree, or beginning of the fourth, nay, of a causticke quality, and nature (as Discorides is of opinion) should here be predominant, then the water of this fountaine must needs bee of great heat and acrimony; and so become not onely unprofitable, but also very hurtfull for mans use to be drunke, or inwardly taken.
To which objection (not to take any advantage of the answer, which many learned Physitians doe give, viz. that vitrioll is not hot, but cold) I say:
