Note 3 — BOOK III.

This work contains contributions from various quarters. I have not, however, made an equal use of all; as I believe some pictures to be copies, which are there referred to as originals; and as several names there mentioned, may with propriety be omitted. In my references, I shall often cite the collections; sometimes also the authors of some more considerable treatises, as P. Civalli, Terzi, Sig. Agostino Rossi, Sig. Arciprete Lazzari, respecting whom I must refer to the second index, where will be found the titles of their respective works.
