At ten o'clock the Mayor of Thun was announced. He was dressed in the French fashion, in black, and had a manner at once graceful and polite that pleased me. He was middle-aged, and enjoyed a considerable position in the Government. He insisted on my reading the letter that M. de Chavigni had written to him on my account. It was so flattering that I told him that if it had not been sealed I should not have had the face to deliver it. He asked me for the next day to a supper composed of men only, and for the day after that, to a supper at which women as well as men would be present. I went with him to the library where we saw M. Felix, an unfrocked monk, more of a scribbler than a scholar, and a young man named Schmidt, who gave good promise, and was already known to advantage in the literary world. I also had the misfortune of meeting here a very learned man of a very wearisome kind; he knew the names of ten thousand shells by heart, and I was obliged to listen to him for two hours, although I was totally ignorant of his science. Amongst other things he told me that the Aar contained gold. I replied that all great rivers contained gold, but he shrugged his shoulders and did not seem convinced. I dined with M. de Muralt in company with four or five of the most distinguished women in Berne. I liked them very well, and above all Madame de Saconai struck me as particularly amiable and well-educated. I should have paid my addresses to her if I had been staying long in the so-called capital of Switzerland. The ladies of Berne are well though not extravagantly dressed, as luxury is forbidden by the laws. Their manners are good and they speak French with perfect ease. They enjoy the greatest liberty without abusing it, for in spite of gallantry decency reigns everywhere. The husbands are not jealous, but they require their wives to be home by supper-time. I spent three weeks in the town, my time being divided between my dear Dubois and an old lady of eighty-five who interested me greatly by her knowledge of chemistry. She had been intimately connected with the celebrated Boerhaave, and she shewed me a plate of gold he had transmuted in her presence from copper. I believed as much as I liked of this, but she assured me that Boerhaave possessed the philosopher's stone, but that he had not discovered the secret of prolonging life many years beyond the century. Boerhaave, however, was not able to apply this knowledge to himself, as he died of a polypus on the heart before he had attained the age of perfect maturity, which Hypocrates fixes at between sixty and seventy years. The four millions he left to his daughter, if they do not prove that he could make gold, certainly prove that he could save it. The worthy old woman told me he had given her a manuscript in which the whole process was explained, but that she found it very obscure. "You should publish it," said I. "God forbid!" "Burn it, then." "I can't make up my mind to do so."
