antiquity of signatures, catchwords, and numerals; and is enriched with a number of plates of watermarks of the paper in ancient books. This catalogue, which is rarely seen in our own country, is well worth a place in any library. It is a pity the typographical execution of it is so very indifferent. For the credit of a bibliographical taste, I hope there were a few copies struck off upon LARGE PAPER.----SION COLLEGE. _Catalogus universalis librorum omnium in Bibliotheca Collegii Sionii apud Londinenses_; Londini, 1650, 4to. _Ejusdem Collegii librorum Catalogus, &c., Cura Reading_, Lond., 1724, fol. As the first of these catalogues (of a collection which contains some very curious and generally unknown volumes) was published before the great fire of London happened, there will be found some books in it which were afterwards consumed, and therefore not described in the subsequent impression of 1724. This latter, which Tom Osborne, the bookseller, would have called a "pompous volume," is absolutely requisite to the bibliographer: but both impressions should be procured, if possible. The folio edition is common and cheap.----SMITH [CONSUL]. _Bibliotheca Smithiana, seu Catalogus Librorum D.J. Smithii Angli, per cognomina Authorum dispositus._ Venetiis, 1755, 4to. _A Catalogue of the curious, elegant, and very valuable library of Joseph Smith, Esq., His Britannic Majesty's Consul at Venice, lately deceased_, 1773, 8vo. These are the catalogues of the collections of books occasionally formed at Venice, by Mr. Joseph Smith, during his consulship there. The quarto impression contains a description of the books which were purchased "en masse" by his present majesty. It is singularly well executed by Paschali, comprehending, by way of an appendix, the prefaces to those volumes in the collection which were printed in the fifteenth century. I possess a brochure of 71 pages, containing a catalogue of books printed in the fifteenth century, which has Consul Smith's arms at the beginning, and, at the end, this subscription, "Pretiosissima haec librorum collectio, cujusvis magni principis Bibliotheca dignissima, constat voluminibus ccxlviii." The title-page has no date. I suspect it to be the same catalogue of books which is noticed at p. 77, ante, and which probably the Consul bought: forming the greater part of his own library of early printed books. See too the _Bibliogr. Miscellany_, vol. ii., 72. The collection of 1773 was sold by auction, for Mr. Robson, by Messrs. Baker and Leigh--and a fine one it was. Among these books, the Spira Virgil of 1470, printed UPON VELLUM, was purchased for _only twenty-five guineas_! Excidat ille dies aevo--ne postera credant Saecula--!
