Translation, by R. Brewin, of "Lettres sur le célèbre compositeur Jh. Haydn [etc.]" The life of Haydn is, in the main, a plagiarism of G. Carpani's Le Haydine (Milan, 1812) The biographical part of the Mozart, credited by Beyle to Schlichtegroll, is practically a reproduction of Winckler's Notice biographique sur Jean-Chrystostome-Wolfgang-Théophile Mozart (Paris, 1801) with one anecdote aded from another source. The letter on Metastasio, according to P. Hazard, borrows largely from Baretti. cf. M.H. Beyle. Vies de Haydn, de Mozart et de Métastase; texte étalbi et annoté par Daniel Muller, préface de Romain Rolland (Paris, Champion, 1914); P. Hazard. Vie de Stendhal (Paris, 1927) The notice of Mozart, attributed by Muller to C. Winckler, is by T. F. Winckler. cf. Fétis, Biog. univ. des musiciens. 2. éd. viii, 476; Quérard, France litt., A. Schurig, Wolfgang Amade Mozart (Leipzeig, 1923) I, 11 "Canon cancrizans a 3 voce. Haydn": p. [129]
