For certain engravers, on whose work no date has been found, a century has been named approximately from an examination of the plates they produced. Some of this information must necessarily be conjectural, and Mons. Poulet-Malassis mentions certain artists and engravers of book-plates of whose work it has not been possible either to obtain copies, or any information whatever. For facility of reference a strictly alphabetical arrangement of the names has been adopted. Wherever it was possible, the inscriptions and signatures have been copied from the book-plates themselves, carefully preserving the arbitrary contractions, the obsolete orthography, and even the errors and the faulty accentuation found on many of them. It will be observed that Mr. as a contraction for _Monsieur_ was formerly more generally used in France than it now is, whilst Escuyer, Escuier, or Ecuyer (for Esquire) was occasionally added after a gentleman’s name, a custom which has, since the Revolution, become quite obsolete. One of the latest examples of the use of this title will be found on the ex-libris of Jean François-Gillet, dated 1778, of which a reproduction appears on p. 96. A List of Artists and Engravers.
