After dinner walked to the Opera through the rain: tried the pit first, but afterwards went to Lady Burghersh’s box, where I found her and Sir William Drummond. The opera, “Il Medico Ciabattino;” the music by Generale, who was the same that composed the “Baccanali di Roma,” which I liked so much at Venice. (I find either Rossini or he has made an opera of “Othello.”) The ballet was on the story of “Gabrielle de Verzy,” [Gabriella di Vergy] and, for an Italian ballet, very good; the tournament of the horses well managed, and the whole spectacle splendid.
