Ceran._ Paris, 1780, 8vo., again in 1791, 8vo. These catalogues were compiled by De Bure, and are carefully executed. Some of the books noticed in them are sufficiently curious and rare.----CLEMENTINO-VATICANA. _Bibliotheca Orientalis Clementino Vaticana, in qua manuscriptos codices Orientalium Linguarum recensuit Joseph Simonius Assemanus_, Romae, 1719. Folio, four vols. Asseman's son compiled an excellent catalogue of the Oriental MSS. in the Medico-Laurentian library; but this work of the father is more curious and elaborate. Whenever a few half-guineas can procure it, let the country-settled philologist send his "henchman" to fly for it!--"Speed, Malise, speed." But alas! Santander tells us that copies of it are rare. _Cat. de Santander_, vol. iv., no. 6287.----COLBERT. _Bibliotheca Colbertina: seu Catalogus Librorum Bibliothecae quae fuit primum J.B. Colbert, deinde J.B. Colbert (fil) postea J. Nic. Colbert, ac demum C.L. Colbert._ Parisiis, 1728, 8vo., three vols. The preface to this valuable catalogue (executed by Martin) gives us a compressed, but sufficiently perspicuous, account of the auspices under which such an extensive and magnificent collection was assembled and arranged. It contains not fewer than 18,219 articles; being perhaps 60,000 volumes. The celebrated Baluze was the librarian during the life of the former branches of the Colbert family; a family which, if nothing remained to perpetuate their fame but this costly monument of literary enterprise, will live in the grateful remembrance of posterity--but it wants not even such a splendid memorial! The lover of fine and curious books will always open the volumes of the COLBERT CATALOGUE with a zest which none but a thorough bred bibliomaniac can ever hope to enjoy.----CONSEIL D'ETAT. _Catalogue des livres de la Bibliotheque du Conseil d'Etat (par M. Barbier, Bibliothecaire du Conseil d'Etat)._ Paris, an. xi. (1802), folio. "This catalogue is most superbly executed. The richness of the materials of which it is composed, the fine order of its arrangement, and the skilful researches exhibited in it relating to anonymous authors, are worthy of the typographical luxury of the national press, from which this curious work was put forth. It will be perfect in three parts: the third part, containing the supplement and tables, is now at press." (A.D. 1804.) The preface and table of the divisions of this catalogue were published in a small 8vo. volume, 1801. This information I glean from Peignot's _Curiosites Bibliographiques_, p. lix.; and from the _Cat. de Boutourlin_, no. 3892, I learn that only 190 copies of so useful, as well as splendid, a work were printed, of which the French government took upon itself the distribution.----CORDES.
