Italian at Toulouse, and who, as he said, had proved its efficacy. I retained this man in my service, that we might see the end of the experiment. I then, by means of strong distillations, tried to calcinate gold and silver; but all my labour was in vain. The weight of the gold I drew out of my furnace was diminished by one-half since I put it in, and my four hundred crowns were very soon reduced to two hundred and thirty. I gave twenty of these to my Italian, in order that he might travel to Milan, where the author of the receipt resided, and ask him the explanation of some passages which we thought obscure. I remained at Toulouse all the winter, in the hope of his return; but I might have remained there till this day if I had waited for him, for I never saw his face again.
"In the succeeding summer there was a great plague, which forced me to quit the town. I did not, however, lose sight of my work. I went to Cahors, where I remained six months, and made the acquaintance of an old man, who was commonly known to the people as 'the Philosopher;' a name which, in country places, is often bestowed upon people whose only merit is, that they are less ignorant than their neighbours. I shewed him my collection of alchymical receipts, and asked his opinion upon them. He picked out ten or twelve of them, merely saying that they were better than the others. When the plague ceased, I returned to Toulouse, and recommenced my experiments in search of the stone. I worked to such effect that my four hundred crowns were reduced to one hundred and seventy.
"That I might continue my work on a safer method, I made acquaintance, in 1537, with a certain abbé who resided in the neighbourhood. He was smitten with the same mania as myself, and told me that one of his friends, who had followed to Rome in the retinue of the Cardinal d'Armagnac, had sent him from that city a new receipt which could not fail to transmute iron and copper, but which would cost two hundred crowns. I provided half this money, and the abbé the rest; and we began to operate at our joint expense. As we required spirits of wine for our experiment, I bought a tun of excellent vin de Gaillac. I extracted the spirit, and rectified it several times. We took a quantity of this, into which we put four marks of silver and one of gold that had been undergoing the process of calcination for a month. We put this mixture cleverly into a sort of horn-shaped vessel, with another to serve as a retort; and placed the whole apparatus upon our furnace to produce congelation. This experiment lasted a year; but, not to remain idle, we amused ourselves with many other less important operations. We drew quite as much profit from these as from our great work.
"The whole of the year 1537 passed over without producing any
