Claire de Kersaint, duchess of DURAS (1778-1828) woman of letters. L.A.S., to Count Louis de Fontanes; 2 pages in-8. She asks him to give her tomorrow's evening: "I will have no one but Mme Svetchine, this Russian lady whom you have conquered, she is dying to hear the Six tilleuls, I dare not ask for them, you have treated me so badly all winter that I no longer believe I have any rights. But think nevertheless that it is an old debt that you will pay there, and that it is not a great commitment for the future to grant people what they have been asking for for two or three years, and what they have been promised a hundred times"... Former collection Édouard Herriot (with autograph folder).
