[Footnote 30: Nissen has incorrectly given the idea that "the well-known Dr. Messmer, the friend of the Mozarts," was the celebrated magnetiser of that name. Helfert (Die österr. Volkschule, I., p. 132.) identifies Mozart's Messmer, who became a member of the medical faculty in 1767. In 1773 his wife inherited a half share in a house on the Landstrasse, consistently with which L. Mozart writes to his wife from Vienna (August) that Fr. v. Messmer has come into considerable property since the death of her mother. A "young Herr. v. Messmer," a cousin, was director of the Normal School in 1773.] [Footnote 31: E. Schelle, Berl. Mus. Ztg. Echo, 1864, No. 38.] [Footnote 32: "'Le Devin du Village' est un intermède charmant dont les paroles et la musique sont de M. Rousseau," writes Grimm (June 23, 1753) to Gottsched (Danzel, Gottsched, p. 351). He speaks of it again on December 15, 1753 (Corr. Litt., I., p. 92), as an "intermède agréable, qui a eu très-grand succès à Fontainebleau et à Paris;" and again, in February, 1754, as an "intermède français très-joli et très-agréable" (Ibid.,p. 112). He passes it over, however, in his account at a later date of Rousseau's musical works, and mentions only his unsuccessful opera, "Les Muses Galantes."] [Footnote 33:La Harpe. Corr. Litt., II., p. 59.] [Footnote 34: A. M. Z., XXI., p. 841. XXIII., p. 141. Berlioz, Voy. Mus., I., p. 389.] [Footnote 35: Adam (Souv. d'un Music., p. 198), suggests that Rousseau's score may have been revised by Francoeur.] [Footnote 36: On the subject of recitative, Rousseau speaks exhaustively and to the point, both in his Dictionnaire de Musique, and in the Lettre sur la Musique Française. (Ouvres, XI., p. 296.)] [Footnote 37: It was maintained by some that Rousseau only wrote the words, and intrusted the composition to a musician in Lyons (A. M. Z., XIV., p. 469; Castil-Blaze; Molière Musicien, II., p. 409), an accusation which Grétry contradicted. Rousseau tried to refute it by a second opera, which, however, did not succeed. (La Harpe, Corr. Litt., II., p. 370. Adam, Souv. d'un Mus., p. 202.)] [Footnote 38: An English adaptation by Burney failed in London in 1766 (Parke, Mus. Mém., II., p. 93). German versions were produced by Leon (Teutsch. Merc., 1787, II., p. 193) and C. Dielitz (Berlin, 1820).] [Footnote 39: Théätre du Favart, V., 1 (Paris, 1763). A book of the words, printed at Amsterdam in 1758, has the remark: "Représenté à Bruxelles, Nov., 1753, par les Comédiens François sous les ordres de S. Alt. Roy."] [Footnote 40: Grimm, Corr. Litt., IV., pp. 400, 417.] [Footnote 41: Dictionn. d. Théätre, VI., p. 228; Theaterkal. 1776.]
