Some of these are exceedingly difficult, but Cherubini solved the whole of them.
Conscious by this time of the need of regular study of his chosen art, he placed himself under the severe training of Cherubini, by which the special qualities of the young composer were admirably developed.
In 1829 he was elected member of the Institute, in 1830 he was named director of the court concerts, and in 1842, at the wish of Louis Philippe, he succeeded Cherubini as director of the Conservatoire.
His numerous works include the musical comedy, Pierre le Grand (1790), for Gretry's music, and the opera, Les Deux Journees (1800), music by Cherubini; also L' Abbe de l'epee (1800), and some other plays; and Causeries d'un vieillard (1807), Contes a ma fille (1809), and Les Adieux du vieux conteur (1835).
For recent canonical texts: Richter's edition of the council of Trent (Leipzig, 1863); the Collectanea S.C. de Propaganda Fide (Rome, 1893); the Bullariunt, a collection of papal acts and constitutions; the editions of Cocquelines (28 vols.,Rome, 1733-1756), and of Cherubini (19 vols., Luxemburg, 1727-1758), which are better than the enlarged reprint of Turin, which was unfinished (it goes up to 1730).
