ment. It is believed that the oil he makes use of, is gold or silver reduced to that state. He leaves it for a long time exposed to the rays of the sun. He told me that it generally took him six months to make all his preparations. I told him that, apparently, the king wanted to see him. He replied that he could not exercise his art in every place, as a certain climate and temperature were absolutely necessary to his success. The truth is, that this man appears to have no ambition. He only keeps two horses and two men-servants. Besides, he loves his liberty, has no politeness, and speaks very bad French; but his judgment seems to be solid. He was formerly no more than a blacksmith, but excelled in that trade without having been taught it. All the great lords and seigneurs from far and near come to visit him, and pay such court to him, that it seems more like idolatry than any thing else. Happy would France be if this man would discover his secret to the king, to whom the superintendent has already sent some lingots! But the happiness is too great to be hoped for; for I fear that the workman and his secret will expire together. There is no doubt that this discovery will make a great noise in the kingdom, unless the character of the man, which I have just depicted to you, prevent it.

In another letter to the same person, dated the 27th of January 1707, M. de Cerisy says, "My dear cousin, I spoke to you in my last letter of the famous alchymist of Provence, M. Delisle. A good deal of that was only hearsay, but now I am enabled to speak from my own experience. I have in my possession a nail, half iron and half silver, which I made myself.

All the country have their eyes upon this gentleman; some deny loudly, others are incredulous; but those who have seen acknowledge the truth. I have read the passport that has been sent to him from court, with orders that he should present himself at Paris early in the spring. He told me that he would go willingly, and that it was himself who fixed the spring for his departure; as he wanted to collect his materials, in order that, immediately on his introduction to the king, he might make an experiment worthy of his majesty, by converting a large quantity of lead into the finest gold. I sincerely hope that he will not allow his secret to die with him, but that he will communicate it to the king. As I had the honour to dine with him on Thursday last, the 20th of this month, being seated at his side, I told him in a whisper that he could, if he liked, humble all the enemies of France. He did
