Know also that any flint taken out of River water, (and put into a gourd glasse, having River water poured upon it, that the glasse may bee filled, which Water is againe to bee distilled off as long as a drop will arise, and the Stone dryed, and the Glasse againe filled with this Water, and againe distilled off, and this done so long till the Glasse bee filled with this Stone) may in a few dayes by the Art of Alchymie bee made very great, which the Archeius of the Waters could scarce doe in many yeers. If then thou breake the Glasse, thou shalt have a Flint in the forme of the Glasse, as if it had been put into the Glasse, and although this bee not for profit, yet it is a thing that is strange, and wonderfull. [Illustration: *decorative divider*] OF THE NATVRE Of Things. _THE THIRD BOOK._ _Of the preservations of Naturall things._ [Sidenote: The enemies of things are to be knowne.] [Sidenote: Death is the enemie of things.] [Sidenote: There is a Contrariety found in all things.] That things may bee preserved, and kept from harm, it is necessary in the first place to know what is an enemie to them, that so they may be preserved from that, & not be hurt, or corrupted by it either in substance, vertue, power, or any way whatsoever. Much therefore in this case depends upon the knowing of the Enemie of all Naturall things. For who can take heed of danger when hee doth not know what can hurt him? Truly no body; Wherefore it is necessary to know ones Enemie, For there are many sorts of Enemies. Wherefore it is as necessary to know evill things, as good things: for who can know what is good, without the knowing of what is evill? Truly no body. So no man can know what a blessing health is, that was never sick. Who knows what joy is, that was never heavy, or sad? And who can rightly understand what God is, who knew nothing of the Devil? Wherefore when God made known to us the Enemie of our Soul, _viz._ the Devill, he also signified to us the Enemie of our life, _viz._ Death, which is the Enemie of our body, of our health, and the Enemie of Medicinall, and all naturall things: also he made known to us how, and by which means it may be shunned. For as there is no disease against which there is not created, and found some remedy, which should cure, and expell it: so also there is alwaies one thing ordained against another, one Water against another, one Stone against another, one Minerall against another, one Poison against another, one Metall against another: and so in many more things, all which it is not requisite here to recite.
