I am compelled to believe the Aurifick, and Argentifick Stone; because at several distinct: times, with my own hand, made projection of one Grane of this Powder, upon some thousands of Granes of Argentvive hot in a Crucible; and in the presence of our principal friends, the business, with a pleasing admiration, succeeded well in the Fire: as our books promise Thee, &c.
The same.
He, who first gave me the Powder, had at least, so much thereof, as would be sufficient for transmuting two hundred thousand pound weight of Metal, into Gold, &c..
The same.
For he gave to me not so much as half a grane of that Powder, and with that were transmuted nine ounces, and three quarters of an ounce of Argetitvive. That was given me one Evening by a strange Friend, &c.
The same
So also it is written, that sixty years since, Alexander Scotus, made projection of that kinde, in the trust: famous City of Colonia and Hanovia, &c.
I cannot in this place over-pass, some Examples worthy of note, touching the possibility of Transmutation.
Read the following true Extract out of an Epistle written by Doctor Kufflerus.
Kufflerus: Artist, I found-in my own Laboratory, an Aqua-fortis. Secondly, I again found another in the Laboratory, Caroli de Roy; this Aqua-Fortis I poured upon the Calx of Sol, prepared of Gold, in the Vulgar manner, and after the third Cohobation, it sublimed the Tincture of Gold with it self in the Neck of the Retort; this Tincture I mixed with Silver, precipited in the vulgar manner, and I saw that one ounce of the sublimed Tincture of Gold, with ordinary Flux in a Crucible, had transmuted one ounce, and halfe of the two ounces of precipitate Silver, into the best Gold: but a third part of the Silver yet remaining, was a white and fixed Gold: the other two parts thereof were perfect Silver, fixed in every examen of Fire. This is my experience, after this time, we could never find the like Aqua-fortis. I, Helvetius saw this Gold white, and without Tincture.
