He [Pompeo Batoni] has two daughters. The eldest is a scholar of Signor Santarelli and sings divinely with more grace, taste and expression than any female in public or private I ever heard. She was so obliging as to sing 6 or 8 capital airs in different styles, and all charmingly but her fort is the pathetic. She has a good shake and well toned voice an admirable portamento with great compass and high finishing in all she attempts. Indeed she does infinite credit to her master for he has contrived to unite the falset so with the real voice, that ‘tis very difficult to say where it begins.
