[Footnote 156: MICHAEL DENIS, the translator of Ossian, and a bibliographer of justly established eminence, was principal librarian of the Imperial library at Vienna, and died in the year 1800, at the age of 71. His _Supplement to Maittaire's Typographical Annals_, in two parts or volumes, 1789, 4to., is a work of solid merit, and indispensable to the possessor of its precursor. The bibliographical references are very few; but the descriptions of the volumes are minutely accurate. The indexes also are excellent. In the year 1793, Denis published the first volume (in three thick parts in folio) of his _Codices Manuscripti Theologici Bibl. Palat. Vindob._; a production which the reader will find somewhat fully described in the ensuing pages. The second volume appeared after his death in 1801. In 1795-6, came forth his second edition of an _Introduction to the Knowledge of Books_, in two quarto volumes; unfortunately written in the German language--but mentioned with approbation in the first volume of the _Mem. de l'Inst._, p. 648. Consult also Peignot's _Dict. de Bibliologie_, vol. i., p. 122; ii., 232.----ARMAND GASTON CAMUS is a bibliographer of very first rate reputation. The reader has only to peruse the following titles of some of his works, and he will certainly bewail his ill fortune if they are not to be found in his library. 1. _Observations sur la distribution et le classement des livres d'une Bibliotheque_: 2. _Additions aux memes_; 3. _Memoire sur un livre Allemand_ (which is the famous TEWRDANNCKHS; and about which is to be hoped that Mr. Douce will one day favour us with his curious remarks): 4. _Addition au meme_: 5. _Memoire sur l'histoire et les procedes du Polytypage et de la Stereotypie_: 6. _Rapport sur la continuation de la Collection des Historiens de France, et de celle des Chartres et Diplomes_: 7. _Notice d'un livre imprime a Bamberg en 1462_. All these works are thus strung together, because they occur in the first three volumes of the _Memoires de l'Institut_. This curious book, printed at Bamberg, was discovered by a German clergyman of the name of Stenier, and was first described by him in the _Magasin Hist.-Litt., bibliogr._ Chemintz, 1792: but Camus's memoir is replete with curious matter, and is illustrated with fac-simile cuts. In the "_Notices et Extraits des MSS. de la Bibl. Nationale_," vol. vi., p. 106, will be found a most interesting memoir by him, relating to two ancient manuscript bibles, in two volumes folio, adorned with a profusion of pictures: of some of which very elegant fac-similes are given. These pictures are 5152 in number! each of them having a Latin and French verse beautifully written and illuminated beneath.--Camus supposes that such a
