Morning at the Office. Nothing new of any importance. Studied but not with effect. In the afternoon copied some of the Lecture on Practice. Went with George to the Theatre in Common Street. The first play was the Wonder or a Woman keeps a Secret by Mrs. Centlivre.1 It is tolerably well performed. But my principal object in going was to see the French Opera Dancers who are here.2 I was much delighted. The music here is fine. There is such a union of all attractive circumstances in this display, that it is not wonderful that the senses of many 188become bewildered. It is a new thing that a Boston audience can bear them. But the world wags and we change. Afterpiece, the Romp, which I have heard often but still admire the music.
