Through Franklin, Jefferson was introduced to Madame d'Houdetot, who had unlimited admiration for a man who not only was an American and a philosopher, but who also knew the names of American plants and trees much more thoroughly than her dear Doctor. He obtained for her seeds, bulbs, and trees to be planted in the park of Sannois.[104] Through Franklin also he met Madame Helvétius and her two abbés, who always wrote jointly to Jefferson.[105] At her house, he saw Cabanis, then a very young man, Destutt de Tracy and abbé Morellet. He attended concerts at Madame d'Houdetot's brother's house, but above all he was attracted by Lafayette's family and friends. It was large enough for a man of more leisure and more worldly tendencies. There was the Marquis himself and his charming wife, who befriended Martha and wrote Jefferson several notes filled with that delightful eighteenth-century "_sensibilité_" and amiability of which we have lost the secret. There was also Madame de Tessé, Lafayette's cousin, who was, however, considerably older than the Marquis and whom he called "aunt." Jefferson saw her in Paris and visited her often at Chaville, where Short stayed for weeks at a time, perfecting himself in the French language and the ways of French society. She loved trees, good paintings, fine buildings, statues, and music, and did much to educate Jefferson's taste in these matters. Not mentioned by his biographers, Madame de Corny played a not inconsiderable part in Jefferson's sentimental life. Young, pretty, witty, and married to a husband much older than herself, she enjoyed Jefferson's company, took with him many walks in the Bois de Boulogne and perhaps, secretly, found him too scrupulously polite and too respectful.[106] There were also several other women, Madame de Tott, a distinguished painter, the vivacious and charming Lucy Paradise, Comtesse Barziza, a real "_enfant terrible_", irresponsible, outspoken, who in her letters to Jefferson listed all the scandals of the days.[107] And one must not forget among Jefferson's feminine acquaintances the old Comtesse de la Rochefoucauld, dignified, sarcastic, a terrible bore at times, whom on many occasions he vainly tried to avoid.
