“Wait a moment,” said the alchemist, “let it get cool;” and it cooled almost directly.

“Take it; it is yours,” said he.

I took up the piece of money and found it had become gold.  I felt perfectly certain that he had smuggled my silver piece away, and had substituted a gold piece coated with silver for it.  I did not care to tell him as much, but to let him see that I was not taken in, I said,—­

“It is really very wonderful, but another time you should warn me what you are going to do, so that the operation might be attentively watched, and the piece of money noted before being placed on the burning coal.”

“Those that are capable of entertaining doubts of my art,” said the rogue, “are not worthy to speak to me.”

This was in his usual style of arrogance, to which I was accustomed.  This was the last time I saw this celebrated and learned impostor; he died at Schlesing six or seven years after.  The piece of money he gave me was pure gold, and two months after Field-marshal Keith took such a fancy to it that I gave it him.

I left Tournay the next morning, and stopped at Brussels to await the answer of the letter which I had written to M. de Bragadin.  Five days after I got the letter with a bill of exchange for two hundred ducats.

I thought of staying in Brussels to get cured, but Daturi told me that he had heard from a rope-dancer that his father and mother and the whole family were at Brunswick, and he persuaded me to go there, assuring me that I should be carefully looked after.

He had not much difficulty in getting me to go to Brunswick, as I was curious to see again the mother of my godson, so I started the same day.  At Ruremonde I was so ill that I had to stop for thirty-six hours.  At Wesel I wished to get rid of my post-chaise, for the horses of the country are not used to going between shafts, but what was my surprise to meet General Bekw there.

After the usual compliments had passed, and the general had condoled with me on my weak state of health, he said he should like to buy my chaise and exchange it for a commodious carriage, in which I could travel all over Germany.  The bargain was soon struck, and the general advised me to stay at Wesel where there was a clever young doctor from the University of Leyden, who would understand my case better than the Brunswick physicians.

Nothing is easier than to influence a sick man, especially if he be in search of fortune, and knows not where to look for the fickle goddess.  General Bekw——­, who was in garrison at Wesel, sent for Dr. Pipers, and was present at my confession and even at the examination.

I will not revolt my readers by describing the disgusting state in which I was, suffice it to say that I shudder still when I think of it.
