2. _Arsenal Library, Paris._--This library, founded by the Marquis de Paulmy, formerly ambassador of France in Poland, was in 1781 acquired by the Count d'Artois, who united to it nearly the whole of the library of the Duke de la Valliere. It possesses the most complete collection extant of romances, since their origin in modern literature; of theatrical pieces or dramas, from the epoch of the Moralities and Mysteries; and of French poetry since the commencement of the sixteenth century. It is less rich in other branches, but it has all works of importance, and in particular contains historical collections which are not to be found elsewhere. 3. _Library of Ste Genevieve, Paris._--The foundation of this library dates as early as the year 1624, when Cardinal de Rochefoucauld, having reformed the Abbey of Sainte-Genevieve, made it a present of 600 volumes. At present it contains 160,000 printed volumes and 2000 manuscripts. In it may be found all the academical collections, and a complete set of Aldines; it is particularly rich in historical works; and its most remarkable manuscripts are Greek and Oriental. Its typographical collections of the fifteenth century are not more valuable for their number than the high state of preservation in which they are found. This library is open of an evening, and is much resorted to by students, and men of the operative classes. 4. _Mazarin Library, Paris._--This library, as its name denotes, was instituted by Cardinal Mazarin. The formation of it was intrusted to the learned Gabriel Naude, who, having first selected all that suited his purpose in the booksellers' shops in Paris, travelled into Holland, Italy, Germany, and England, where the letters of recommendation of which he was the bearer enabled him to collect many very rare and curious works. Cardinal Mazarin, by his will, bequeathed it to the college which he founded, and in 1688 it was made public. It is remarkable for a great number of collections containing detached pieces and small treatises, which date as far back as the fifteenth century, and exist nowhere else; nor has any other library so complete a body of the ancient books of law, theology, medicine, and the physical and mathematical sciences. It also possesses a most precious collection of the Lutheran or Protestant authors. In one of the halls are placed models in relief of the Pelasgic monuments of Italy and Greece; in another is a terrestrial globe, eighteen feet in diameter, formed of plates of copper, and executed by order of Louis XVI.; but this instrument, which is unique in Europe, is unfortunately unfinished, being destitute of several requisite circles.
