The plate is an interesting example of the artistic regularity which marks the early period of Louis XV. (See next page.) [Illustration: BOOK-PLATE OF THE COLLEGE OF EU.] The armorial plate of the Abbé de Bourbon-Rothelin shows by its inescutcheon, and its supporters, that the owner was a descendant of the royal house of Bourbon. Charles d’Orléans, Abbé de Rothelin, a son of Henri d’Orléans, Marquis de Rothelin, was born August 5, 1691, and died July 17, 1744. He was an ardent collector of medals, books, and manuscripts, and was esteemed one of the most learned men of his day. At his death, his library, which was especially rich in early theological works, was sold and dispersed, but his collection of medals was acquired entire for the museum of the Escurial. (See reproduction, page 187.) [Illustration: BOOK-PLATE OF M. LE CURÉ DUBUT.] The arms, stamped on the sides of the books bound for him resembled those on his ex-libris, but without the columns in the background. [Illustration: BOOK-PLATE OF THE ABBÉ DE GRICOURT, 1750.] A very large ecclesiastical plate is that of Franciscus Tristanus de Cambon: Episcopus Mirapiscensis. This plate is in the best style of the early period of Louis XVI., and is signed _J. Mercadier. Inv. et sculp._ The shield is surmounted by the coronet of a count, over which is the bishop’s hat. The plate of Archambault is a handsome specimen of the work of Sergent, signed “Sergent scul. Carnuti.” The date is very faint, but appears to be 1773. [Illustration: BOOK-PLATE OF D’ARCHAMBAULT.] “Affaires du Clergé” on the open book, the tables with the commandments, the mitre and crozier, sufficiently indicate that the owner of the plate was connected with the Church. [Illustration: BOOK-PLATES OF J. A. LE MERCIER.] _Des Livres de M. Dubut_ is the title of the pretentious book-plate of the Curé de Viroflay, signed Le Roy, and dated 1782. Here we have the arms of this pious son of the Church going straight to Paradise on a thunder-cloud, under the protection of two rather mundane-looking ladies. The world, the flesh, and--but no--the cross of St. Louis in the background prevents the completion of the trio. (See page 181.) In a somewhat similar style of thunder-cloud decoration is the dated plate of the Abbé de Gricourt, already referred to. [Illustration: BOOK-PLATE OF THE REV. FATHER INGOLD.] The plates of J. A. Le Mercier show that at first over his arms he bore the coronet of a count, but that later on, probably during the revolutionary period, he had that erased to make way for a meaningless finial ornament, on the lower half of which the back part of the coronet can still be seen. A modern addition to the French literature on book-plates is a sixteen-page pamphlet, entitled, _Les Ex-Libris Oratoriens_, published in 1892 by Charles Poussielgue, in the Rue Cassette, Paris.
