Bonnefond introduced me to Quillau the father, with whom I agreed to divide the profits, without reckoning the privilege, of which I paid the whole expense. Such were the future proceedings of this Quillau that I lost the expenses of my privilege, never having received a farthing from that edition; which, probably, had but very middling success, although the Abbe des Fontaines promised to give it celebrity, and, notwithstanding the other journalists, had spoken of it very favorably.
The greatest obstacle to making the experiment of my system was the fear, in case of its not being received, of losing the time necessary to learn it. To this I answered, that my notes rendered the ideas so clear, that to learn music by means of the ordinary characters, time would be gained by beginning with mine. To prove this by experience, I taught music gratis to a young American lady, Mademoiselle des Roulins, with whom M. Roguin had brought me acquainted. In three months she read every kind of music, by means of my notation, and sung at sight better than I did myself, any piece that was not too difficult. This success was convincing, but not known; any other person would have filled the journals with the detail, but with some talents for discovering useful things, I never have possessed that of setting them off to advantage.
Thus was my airy castle again overthrown; but this time I was thirty years of age, and in Paris, where it is impossible to live for a trifle. The resolution I took upon this occasion will astonish none but those by whom the first part of these memoirs has not been read with attention. I had just made great and fruitless efforts, and was in need of relaxation. Instead of sinking with despair I gave myself up quietly to my indolence and to the care of Providence; and the better to wait for its assistance with patience, I lay down a frugal plan for the slow expenditure of a few louis, which still remained in my possession, regulating the expense of my supine pleasures without retrenching it; going to the coffee-house but every other day, and to the theatre but twice a week. With respect to the expenses of girls of easy virtue, I had no retrenchment to make; never having in the whole course of my life applied so much as a farthing to that use except once, of which I shall soon have occasion to speak. The security, voluptuousness, and confidence with which I gave myself up to this indolent and solitary life, which I had not the means of continuing for three months, is one of the singularities of my life, and the oddities of my disposition. The extreme desire I had, the public should think of me was precisely what discouraged me from showing myself; and the necessity of paying visits rendered them to such a degree insupportable, that I ceased visiting the academicians and other men of letters, with whom I had cultivated an acquaintance. Marivaux, the Abbe Malby, and Fontenelle, were almost the only persons whom I sometimes went to see.
