article, would make the owner to have been in possession of 100,000 volumes of printed books and MSS. The English library, (vol. iv., pt. ii.) of nearly 3300 articles, comprehended nearly all the best books of the day. There were about 1200 articles of Spanish Literature. Nor was the worthy Consul deficient in the love of the fine arts ("haec est, sitque diu, Senis optimi voluptas et oblectatio," says the compiler of the catalogue); having 11,000 most beautiful prints of subjects relating to the Bible, bound up in 92 atlas folio volumes. Long live the memory of Hulsius; a consular hero of no ordinary renown!----JENA. _Memorabilia Bibliothecae Academicae Jenensis: sive designatio Codicum manuscriptorum illa Bibliotheca et Librorum impressorum plerumque rariorum. Joh. Christophoro Mylio._ Jenae, 1746, 8vo. A work of some little importance; and frequently referred to by Vogt and Panzer. It is uncommon.----JESU SOC. _Bibliotheca Scriptorum Societatis Jesu._ Antv., 1643. Romae, 1676, fol. Although this work is not a professed catalogue of books, yet, as it contains an account of the writings of those learned men who were in the society of the Jesuits--and as Baillet, Antonio, and Morhof, have said every thing in commendation of it--I strongly recommend one or the other of these editions to the bibliographer's attention. I possess the edition of 1643; and have frequently found the most satisfactory intelligence on referring to it. How clever some of the Jesuits were in their ideas of the arrangement of a library may be seen from their "_Systema Bibliothecae Jesuitarum Collegii Ludoviciani_"--which was written by Garnier for the private use of the Louvain college, and which is now extremely difficult to be found. See Maichelius, _de Praecip. Bibl. Parisiens_, p. 128. Their "_Systema bibliothecae collegii Parisiensis societatis Jesu_," 1678, 4to. (or catalogue of books in the college of Clermont), is handsomely noticed by Camus in the _Mem. de l'Inst._, vol. i., 647.----JUST, ST. _Catalogue des livres en tres-petit nombre qui composent la Bibliotheque de M. Merard de St. Just, ancien maitre-d'hotel de Monsieur, frere du Roi (avec les prix d'achat)._ Paris, 1783, 18mo. Of this book, printed upon superfine paper, of the manufactory of d'Annonay, only 25 copies were struck off. _Bibl. Curieuse_, p. 43. Another catalogue of the same collection (perhaps a more copious one) was put forth in 1799, 8vo., prepared by M. Mauger, See _Diction. Bibliographique_, tom. iv., p. xiv.----KROHN. _Catalogus Bibliothecae Praestantissimorum &c., Librorum selectum complectentis. Libros collegit et Literariis Catalogum Animadversionibus instruxit, B.N. Krohn. Editio altera._ Hamb. 1796, 8vo. The preface to this very excellent
