“I have now to assert, from my own experience, facts of transmutation of which I was an eye-witness. I was well acquainted with an artist with whom I have often conversed on the subject, and I saw in his possession the white and the red elixir in very large quantity. He gave me upwards of two ounces of the white medicine, of sufficient virtue to convert 120,000 times its weight into the purest virgin silver. With this treasure I went to work ignorantly upon multiplication, and was caught in the trap of my own covetousness, for I expended or wasted all this tincture. However, I made projection of part of it, which is sufficient for my present purpose, enabling me to assert the possibility of the art from ocular demonstration. I have tinged many times hundreds of ounces into the best silver. Of a pound of mercury I have made within less than a scruple of a pound of silver; of lead, little more waste; but ’tis wondrous to see tin--although a dross was burnt from it, yet its weight increased in the fire. I essayed the medicine on copper, iron, even on brass and pewter, on spelter, solder, tinglass, mercury, and on regulus of antimony; and I can say with truth it conquers all metallic things, and brings them all to perfection. I found there was nothing akin to it but it would tinge into pure silver. Even perfect gold was penetrated and changed into a white glass, that would transmute, but in small quantity, inferior metals into silver; but when this silver was assayed it was found to abide _aquafortis_, cupel of antimony, and weighed as gold, so that it was _white gold_. This was because the white tincture had fermented with red earth, and both virtues coming into projection, produced silver-coloured gold, or silver equalling gold in perfection, but wanting its hue. I did not know the value of this silver till my medicine was nearly gone, and sold eighty ounces of it at the common price, though it was as valuable as gold. I projected the medicine on pure silver, and had a chrystalline metal, like burnished steel or mirror, but there was no increase of virtue in this; it tinged only so much as it would if it had not been projected on silver.
