I required that M. de Francueil should previously employ his interest with that of Jelyote to get my work rehearsed at the operahouse; to this he consented. The Muses Galantes were several times rehearsed, first at the Magazine, and afterwards in the great theatre. The audience was very numerous at the great rehearsal, and several parts of the composition were highly applauded. However, during this rehearsal, very ill-conducted by Rebel, I felt the piece would not be received; and that, before it could appear, great alterations were necessary. I therefore withdrew it without saying a word, or exposing myself to a refusal; but I plainly perceived, by several indications, that the work, had it been perfect, could not have succeeded. M. de Francueil had promised me to get it rehearsed, but not that it should be received. He exactly kept his word. I thought I perceived on this occasion, as well as many others, that neither Madam Dupin nor himself were willing I should acquire a certain reputation in the world, lest, after the publication of their books, it should be supposed they had grafted their talents upon mine. Yet as Madam Dupin always supposed those I had to be very moderate, and never employed me except it was to write what she dictated, or in researches of pure erudition, the reproach, with respect to her, would have been unjust.
This last failure of success completed my discouragement. I abandoned every prospect of fame and advancement; and, without further troubling my head about real or imaginary talents, with which I had so little success, I dedicated my whole time and cares to procure myself and Theresa a subsistence in the manner most pleasing to those to whom it should be agreeable to provide for it. I therefore entirely attached myself to Madam Dupin and M. de Francueil. This did not place me in a very opulent situation; for with eight or nine hundred livres, which I had the first two years, I had scarcely enough to provide for my primary wants; being obliged to live in their neighborhood, a dear part of the town, in a furnished lodging, and having to pay for another lodging at the extremity of Paris, at the very top of the Rue Saint Jacques, to which, let the weather be as it would, I went almost every evening to supper. I soon got into the track of my new occupations, and conceived a taste for them. I attached myself to the study of chemistry, and attended several courses of it with M. de Francueil at M. Rouelle’s, and we began to scribble over paper upon that science, of which we scarcely possessed the elements. In 1717, we went to pass the autumn in Tourraine, at the castle of Chenonceaux, a royal mansion upon the Cher, built by Henry the II, for Diana of Poitiers, of whom the ciphers are still seen, and which is now in the possession of M. Dupin, a farmer general. We amused ourselves very agreeably in this beautiful place, and lived very well: I became as fat there as a monk. Music was a
