Cuvier came down to the very carriage door to receive us, and handed us up narrow, difficult stairs into a smallish room, where were assembled many ladies and gentlemen of most distinguished names and talents. Prony, as like an honest water-dog as ever; Biot (_et moi aussi je suis père de famille_), a fat, double volume of himself--I could not see a trace of the young _père de famille_ we knew--round-faced, with a bald head and black ringlets, a fine-boned skull, on which the tortoise might fall without cracking it. When he began to converse, his superior ability was immediately apparent. Then Cuvier presented Prince Czartorinski, a Pole, and many compliments passed; and then we went to a table to look at Prince Maximilian de Neufchatel's _Journey to Brazil_, magnificently printed in Germany, and all tongues began to clatter, and it became wondrously agreeable; and behind me I heard English well spoken, and this was Mr. Trelawny, and I heard from him a panegyric on the Abbé Edgeworth, whom he knew well, and he was the person who took the first letter and news to the Duchesse d'Angoulême at Mittau, after she quitted France. She came out in the dead of the night in her nightgown to receive the letter. Tea and supper together: only two-thirds of the company could sit down, but the rest stood or sat behind, and were very happy, loud, and talkative: science, politics, literature, and nonsense in happy proportions. Biot sat behind Fanny's chair, and talked of the parallax and Dr. Brinkley. Prony, with his hair nearly in my plate, was telling me most entertaining anecdotes of Buonaparte; and Cuvier, with his head nearly meeting him, talking as hard as he could: not _striving_ to show learning or wit--quite the contrary; frank, open--hearted genius, delighted to be together at home, and at ease. This was the most flattering and agreeable thing to me that could possibly be. Harriet was on the off-side, and every now and then he turned to her in the midst of his anecdotes, and made her completely one of us; and there was such a prodigious noise nobody could hear but ourselves. Both Cuvier and Prony agreed that Buonaparte never could bear to have any answer but a _decided_ answer. "One day," said Cuvier, "I nearly ruined myself by considering before I answered. He asked me, 'Faut-il introduire le sucre de betrave en France?' 'D'abord, Sire, il faut songer si vos colonies----' 'Faut-il avoir le sucre de betrave en France?' 'Mais, Sire, il faut examiner----' 'Bah! je le demanderai à Berthollet.'"
