[109] M. Dupin deserves honourable mention as having helped the editors of the Encyclopædia by procuring information for them as to salt-works (D'Alembert's _Discours Préliminaire_). His son M. Dupin de Francueil, it may be worth noting, is a link in the genealogical chain between two famous personages. In 1777, the year before Rousseau's death, he married (in the chapel of the French embassy in London) Aurora de Saxe, a natural daughter of the marshal, himself the natural son of August the Strong, King of Poland. From this union was born Maurice Dupin, and Maurice Dupin was the father of Madame George Sand. M. Francueil died in 1787. [110] _Mém. de Mdme. d'Epinay_, vol. i. ch. iv. p. 176. [111] _Ib._ vol. i. ch. iv. pp. 178, 179. [112] _Conf._, vii. 46, 51, 52, etc. A diplomatic piece in Rousseau's handwriting has been found in the archives of the French consulate at Constantinople, as M. Girardin informs us. Voltaire unworthily spread the report that Rousseau had been the ambassador's private attendant. For Rousseau's reply to the calumny, see _Corr._, v. 75 (Jan. 5, 1767); also iv. 150.

Also a second example, 84-86. For Byron's opinion of one of these stories, see Lockhart's _Life of Scott_, vi. 132. (Ed. 1837.) [118] _Lettre sur la Musique Française_ (1753), p. 186. [119] _Conf._, ix. 232. [120] _Ib._ vii. 97. [121] Hôtel St. Quentin, rue des Cordiers, a narrow street running between the rue St. Jacques and the rue Victor Cousin. The still squalid hostelry is now visible as Hôtel J.J. Rousseau. There is some doubt whether he first saw Theresa in 1743 or 1745. The account in Bk. vii. of the _Confessions_ is for the latter date (see also _Corr._, ii. 207), but in the well-known letter to her in 1769 (_Ib._ vi. 79), he speaks of the twenty-six years of their union. Their so-called marriage took place in 1768, and writing in that year he speaks of the five-and-twenty years of their attachment (_Ib._ v. 323), and in the _Confessions_ (ix. 249) he fixes their marriage at the same date; also in the letter to Saint-Germain (vi. 152). Musset-Pathay, though giving 1745 in one place (i. 45), and 1743 in another (ii. 198), has with less than his usual care paid no attention to the discrepancy. [122] _Conf._, vii. 97-100.
