At eleven a. m. I rehearsed at Paër's with Baillot for this evening; then I went, or rather ran, with him at full speed to the Court Chapel in the Tuileries, where we heard a glorious mass by Cherubini, admirably performed, as might be expected with the co-operation of such men as Kreutzer, Baillot, Habeneck. Plantade directed, and Cherubini, who talked to me, was among the audience.
