. 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 favorite relaxation. I composed
several trios full of harmony, and of which I may perhaps speak in my
supplement if ever I should write one. Theatrical performances were
another resource. I wrote a comedy in fifteen days, entitled
'l'Engagement Temeraire',--[The Rash Engagement]--which will be found
amongst my papers; it has no other merit than that of being lively.
I composed several other little things: amongst others a poem entitled,
'l'Aliee de Sylvie', from the name of an alley in the park upon the bank
of the Cher; and this without discontinuing my chemical studies, or
interrupting what I had to do for Madam
