Sit mihi, quod nunc est, etiam minus; ut mihi vivam Quod superest aevi, si quid superesse volunt Di. Sit bona librorum et provisae frugis in annum Copia, ne fluitem dubiae spe pendulus horae. _Epist. Lib._ i.: _Epist._ xviii. v., 107. Sir M.M. Sykes, Bart., has a copy of the edition of 1784 [which is in every respect the better one], printed upon FINE VELLUM PAPER. A similar copy of the edition of 1794 is noticed in the _Cat. de Caillard_,(1808) no. 2572. At the sale of M. Meon's books, in 1804, a copy of the first edition, charged with MS. notes of the celebrated Mercier St. Leger, was sold for 30 livres.----RIVE. _Catalogue de la Bibliotheque de l'Abbe Rive, par Archard_, Marseille, 1793, 8vo. A catalogue of the books of so sharp-sighted a bibliographer as was the Abbe Rive cannot fail to be interesting to the collector.----DU ROI [Louis XV.] _Catalogus Codicum Manuscriptorum Bibliothecae Regiae (studio et labore Anicetti Mellot). Paris, e Typog. Reg._, 1739, folio, four vols.----DU ROI. _Des Livres imprimes de la meme Bibliotheque Royale. (Dispose par Messrs. les Abbes Sallier et Boudot, &c.) Paris, De L'Imprim. Royale_, 1739-53, folio, six vols. The most beautiful and carefully executed catalogue in the world: reflecting a truly solid lustre upon the literary reputation of France! The first four volumes, written in Latin, comprehend an account of MSS.: the six last, written in French, of printed works in THEOLOGY, JURISPRUDENCE, and BELLES-LETTRES; the departments of HISTORY and the ARTS AND SCIENCES still remaining to be executed. De Bure told us, half a century ago, that the "Gens de Lettres" were working hard at the completion of it; but the then complaints of bibliographers at its imperfect state are even yet continued in Fournier's last edition of his _Dictionnaire Portatif de Bibliographie_, p. 468. So easy it is to talk; so difficult to execute! I believe, however, that M. Van-Praet, one of the principal librarians, is now putting all engines to work to do away the further disgrace of such unaccountably protracted negligence. My copy of this magnificent set of books is bound in red Morocco, gilt leaves, and was a presentation one from the King "au Comte de Neny, comme une marque de son estime, 1770." I should add that the first volume of "Theology" contains a history of the rise and progress of the royal library, which was reprinted in 8vo., 1782.----DU ROI. _Notices et Extraits des Manuscrits de la Bibliotheque du Roi, Paris. De l'Imprim. Roy._ 1787, 4to., seven vols. It will be obvious to the candid reader that this work could not be better introduced than in the present place; and a most interesting and valuable one it is! My copy of it,
