I said I wanted to be off at day-break, but he would not hear of it, and protested he would be quite hurt if I went away without seeing his wife and his three children. At last I appeased him by saying that we would sup together.

My readers will remember that I had been on the point of marrying Thérèse, and this circumstance made me ashamed of presenting myself to her in such a sorry plight.

In a quarter of an hour the husband arrived with his wife and three children, the eldest of whom looked about six. After the usual greetings and tiresome enquiries after my health, Thérèse sent back the two younger children, rightly thinking that the eldest would be the only one in whom I should take any interest. He was a charming boy; and as he was exactly like his mother, the worthy merchant had no doubts as to the parentage of the child.

I laughed to myself at finding my offspring thus scattered all over Europe. At supper Thérèse gave me news of Tiretta. He had entered the Dutch East India Company’s service, but having been concerned in a revolt at Batavia, he had only escaped the gallows by flight—I had my own thoughts as to the similarity between his destiny and mine, but I did not reveal them. After all it is an easy enough matter for an adventurous man, who does not look where he is going, to get hanged for a mere trifle.

The next day, when I got to Tournay, I saw some grooms walking fine horses up and down, and I asked to whom they belonged.

“To the Comte de St. Germain, the adept, who has been here a month, and never goes out. Everybody who passes through the place wants to see him; but he is invisible.”

This was enough to give me the same desire, so I wrote him a letter, expressing my wish to speak to him, and asking him to name an hour. His reply, which I have preserved, ran as follows:

“The gravity of my occupation compels me to exclude everyone, but you are an exception. Come whenever you like, you will be shewn in. You need not mention my name nor your own. I do not ask you to share my repast, for my food is not suitable to others—to you least of all, if your appetite is what it used to be.”

At nine o’clock I paid my call, and found he had grown a beard two inches long. He had a score of retorts before him, full of liquids in various stages of digestion. He told me he was experimenting with colours for his own amusement, and that he had established a hat factory for Count Cobenzl, the Austrian ambassador at Brussels. He added that the count had only given him a hundred and fifty thousand florins, which were insufficient. Then we spoke of Madame d’Urfe.

“She poisoned herself,” said he, “by taking too strong a dose of the Universal Medicine, and her will shews that she thought herself to be with child. If she had come to me, I could have really made her so, though it is a difficult process, and science has not advanced far enough for us to be able to guarantee the sex of the child.”
