To make an artificiall stone of any forme.
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.
