All articles required for the due maintenance of the library were provided by Platina. The charges for binding and lettering are the most numerous. Skins were bought in the gross—on one occasion as many as 600—and then prepared for use. All other materials, as gold, colours, varnish, nails, horn, clasps, &c., were bought in detail, when required; and probably used in some room adjoining the library.

There are numerous charges for coals, with an amusing apology for their use in winter "because the place was so cold"; and for juniper to fumigate (ad suffumigandum). Brooms are bought to clean the library, and fox-tails to dust the books (ad tergendos libros[1]).

It is therein stipulated that the fees, paid according to custom by all officials appointed to any office vacated by resignation, should thenceforward be transferred to the account of the library[2].

Father Ehrle had already informed me by letter of the existence of a fresco in the Ospedale di Santo Spirito, which he had not had an opportunity of examining himself, but which
