Bap, rap at the door; and in walked a lady and gentleman (Hamilton by name) that Mrs. Bushe introduced to me; she is a surprising ready player on the harpsichord — she played Mr. Purcell’s overture, and one of Handel's, as readily as if she had played them seven years, she has a neat pretty finger, and if she would undergo the slavery of practice, could do what she pleased; but as she plays so agreeably without, and is so much mistress of music, it is riot worth her while.
