THE library that Mr. Sumner has bequeathed to Harvard has just been received. The number of volumes is nearly 3,000, and the value of some of them is very great. That Mr. Sumner had the true love of a bibliophile for beautiful bindings, rare editions, and exquisite texts, is testified by the Didots, the Foulis, the Pickerings, and the Roger Paynes he has collected; and though our opportunities for seeing really fine typography in this country are so rare that we are not trained to appreciate the delicate finish of these books, yet one cannot help admiring the vellum and gilding, the colored leather, and even the ivory and precious stones. The handsomest books in the collection are two reprints of old books full of monkish illustrations of the Florentine school, the one a translation of the Imitation of a Kempis, the other the Livre d'Heures de la Reine Anne de Bretagny. There is also a beautiful manuscript of the XVth Century that is a copy of the works of Thomas Aquinas. There are two books (one a volume of Allatius) which belonged to Louis XIV., and which have on their bindings the crowned L and the Fleur-de-lys. Another book has the crowned N and the French eagle; it belonged to the First Consul. Another binding is stamped with the arms of the Dauphin. Several books contain illustrations by Holbein, and there is a fine set of engravings of the Dance of Death. There are a number of the Aldine edition dating from 1521 and onward. A book printed by Gutenberg in 1460, and one by Faust in 1462, are both older than any book the Library has hitherto contained. Another book has the date 1489, and there is a very rare edition of Plautus, 1578. The collection contains autographs of Samuel Johnson, John Milton, Racine, Drummond, T. N. Taifourd, and S. T. Coleridge. "Comus, 1645," and "Paradise Lost, 1668," are probably copies of the first edition. The manuscripts in Mr. Sumner's library are said to be very valuable, but they are not yet unpacked.
