Bibliothecae Medicae Laurentianae: Angelus Maria Bandinus recensuit, illustravit edidit._ Florent., 1764; 3 vols., 1774; 5 vols., folio. An equally splendid work with the preceding--and much more copious and erudite in regard to intrinsically valuable matter. The indexes are excellent. No extensive philological library should be without these volumes--especially since the name of MEDICI has recently become so popular, from the able biographical memoirs of the family by Mr. Roscoe.----MENARSIANA. _Bibliotheca Menarsiana; ou Catalogue de la Bibliotheque de feu Messire Jean Jaques Charron, Chevalier Marquis de Menars_, &c. A La Haye, 1720, 8vo. A very fine collection of books in all branches of literature. After the "Ordo Venditionis," there is an additional leaf pasted in, signifying that a magnificent copy of Fust's bible of 1462, upon paper, would be sold immediately after the theological MSS. in folio. It brought the sum of 1200 florins. The sale commenced at nine and at two; giving the buyers time to digest their purchases, as well as their dinners, at twelve! "Tempora mutantur!"----MENCKENIUS. _Catalogus Bibliothecae Menckenianae ab Ottone et Burchardo collectae. Editior altera longe emendatior._ Lips., 1727, 8vo. There are some curious and uncommon books in this collection; which evince the taste and judgment of Menckenius, who was a scholar of no mean reputation. Perhaps the word "rare" is too lavishly bestowed upon some of the books described in it.----MEON. _Catalogue des livres precieux singulieres et rares de la Bibliotheque de M. Meon._ Paris, an. xii. (1804), 8vo. A very choice collection of books; catalogued with considerable care.----MERCIER. _Catalogue de la Bibliotheque de M. Mercier, Abbe de Saint Leger_, par. M. De Bure, 1799, 8vo. If the reader has chanced to cast his eye over the account of the Abbe de St. Leger, at p. 61, ante, he will not hesitate long about procuring a copy of the catalogue of the library of so truly eminent a bibliographer.----MERIGOT. _Catalogue des livres de M.J.G. Merigot, Libraire_, par M. De Bure, 1800, 8vo. It is very seldom that this catalogue appears in our own country: which is the more provoking as the references to it, in foreign bibliographical works, render its possession necessary to the collector. Merigot was an eminent bookseller, and prepared a good catalogue of M. Lorry's library, which was sold in 1791, 8vo.----ST. MICHAEL. _Bibliotheca Codicum Manuscriptorum Monasterij Sancti Michaelis Venetiarum, una cum appendice librorum impressorum saeculi_ xv. _Opus posthumum Joannis Bened. Mittarelli._ Venet., 1779, folio. It were much to be wished that, after the example of this and other monasteries, all religious houses, which have large libraries attached to
