I have not observed anything in need of correction in the notes. The “little Tablet” was a famous “Last Supper”, mentioned by Vasari, (page. 232), and gone astray long ago from the Church of S.

(Page 156.) “A canon”, in music, is a piece wherein the subject is repeated-- in various keys: and being strictly obeyed in the repetition, becomes the “Canon”--the imperative law--to what follows. Fifty of such parts would be indeed a notable peal: to manage three is enough of an achievement for a good musician.
