After this breakfast we went to the Duchesse d'Uzès--a little, shrivelled, thin, high-born, high-bred old lady, who knew and admired the Abbé Edgeworth, and received us with distinction as his relations. Her great-grandfather was the Duc de Chatillon, and she is great-granddaughter, or something that way, of Madame de Montespan, and her husband grand-nephew straight to Madame de la Valliere: their superb hotel is filled with pictures of all sizes, from miniatures by Petitôt to full-lengths by Mignard, of illustrious and interesting family pictures--in particular, Mignard's "La Valliere en Madeleine;" we returned to it again and again, as though we could never see it enough. A full-length of Madame de Montespan was prettier than I wished. After a view of these pictures and of the garden, in which there was a catalpa in splendid flower, we departed. This day we dined with Lord Carrington and his daughter, Lady Stanhope: [Footnote: Catherine Lucy, wife of the fourth Earl Stanhope.] the Count de Noé, beside whom I sat, was an agreeable talker. In the evening we received a note from Madame Lavoisier--Madame de Rumford, I mean--telling us that she had just arrived at Paris, and warmly begging to see us. Rejoiced was I that my sisters should have this glimpse of her, and off we drove to her; but I must own that we were disappointed in this visit, for there was a sort of _chuffiness_, and a sawdust kind of unconnected cutshortness in her manner, which we could not like. She was almost in the dark with one ballooned lamp, and a semicircle of black men round her sofa, on which she sat cushioned up, giving the word for conversation--and a very odd course she gave to it--on some wife's separation from her husband; and she took the wife's part, and went on for a long time in a shrill voice, proving that, where a husband and wife detested each other, they should separate, and asserting that it must always be the man's fault when it comes to this pass! She ordered another lamp, that the gentlemen might, as she said, see my sisters' pretty faces; and the light came in time to see the smiles of the gentlemen at her matrimonial maxims. Several of the gentlemen were unknown to me. Old Gallois sat next to her, dried, and in good preservation, tell my mother; M. Gamier (_Richesses des Nations_) was present, and Cuvier, with whom I had a comfortable dose of good conversation. Just as we left the room Humboldt and the Prince de Beauveau arrived, but we were engaged to Madame Recamier.
