science, which had been communicated to me by an 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 showed 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 change whatever: in fact, we might have waited till doomsday for the congelation of our spirits of wine. However, we made a projection with it upon some heated quicksilver; but all was in vain. Judge of our chagrin, especially of that of the Abbé, who had already boasted to all the monks of his monastery, that they had only to bring the large pump which stood in a corner of the cloister, and he would convert it into gold; but this ill luck did not prevent us from persevering. I once more mortgaged my paternal lands for four hundred crowns, the whole of which I determined to devote to a renewal of my search for the great secret. The Abbé contributed the same sum; and, with these eight hundred crowns, I proceeded to Paris, a city more abounding with alchymists than any other in the world, resolved never to leave it until I had either found the philosopher’s stone, or spent all my money. This journey gave the greatest offence to all my relations and friends, who, imagining that I was fitted to be a great lawyer, were anxious that I should establish myself in that profession. For the sake of quietness, I pretended, at last, that such was my object.

“After travelling for fifteen days, I arrived in Paris, on the 9th of January 1539. I remained for a month, almost unknown; but I had no sooner begun to frequent the amateurs of the science, and visited the shops of the furnace-makers, than I had the acquaintance of more than a hundred operative alchymists, each of whom had a different theory and a different mode of working. Some of them preferred cementation; others sought the universal alkahest, or dissolvent; and some of them boasted the great efficacy of the essence of emery. Some of them endeavoured to extract mercury from other metals to fix it afterwards; and, in order that each of us should be thoroughly acquainted with the proceedings of the others, we agreed to meet somewhere every night, and report progress. We met sometimes at the house of one, and sometimes in the garret of another; not only on week days, but on Sundays, and the great festivals of the Church. ‘Ah!’ one used to say, ‘if I had the means of recommencing this experiment, I should do something.’ ‘
