Called upon by the Douglases at three to go and dine at Mr. Thayer’s [an American, to whom their hotel (de Morency) and the Passage du Panorama belongs] at his country house at Sceaux. A large and strange party there: among others the famous M. Say, whom I found agreeable. […] Among the company too was Garat, brother to the old singer of that name, who sings himself with much spirit, and gave an Anacreontic after dinner with great effect. In the evening went to the dance in the park, which was very pretty. Returned and had music. A French girl, Mademoiselle Picheraut, sung some things of Rossini’s, accompanied by Consul of the Opera. I sang too. Home at twelve. Lucy and I chanting duets by moonlight all the way.
