FROISSART'S CHRONICLES.--Who that has ever read the stirring Chronicles of Sir JOHN FROISSART, but will rejoice to learn that an excellent edition of them, upon a new and clear type, and with all the original engravings, is being issued in numbers from the office of the New World? We have never found such a historian as Sir JOHN. Give him a battle to describe, a hero worthy of his pen to hand down to posterity, and what a love of his theme, what _personal_ enthusiasm, does he throw into his glowing records! We have sometimes thought that our worthy and world-renowned progenitor, DIEDRICH KNICKERBOCKER, of blessed memory, derived no small portion of his fervent historical style from a familiar study of his great predecessor. Be that, however, (and every thing else,) as it may, here are the glorious 'Chronicles' of Sir JOHN FROISSART, accessible to all, for a comparative trifle; and the more who embrace this occasion to read them, the fewer stupid people will there be in the country--in our humble opinion. PORT-CHESTER SEMINARY.--This boarding school for young ladies and gentlemen is in Westchester county, in a beautiful situation, and of easy access from the city. It has now for its Principal, RUFUS H. BACON, A. B., a fine scholar, and well skilled in the discharge of his important trusts. The design of the Principal and his subordinate teachers is, to impart a full and thorough knowledge of the branches of a good English education; to fit young men for college and the counting-room; and to prepare the pupils for honor and usefulness, by softening their manners and improving their moral perceptions. Kindness and attention to their neatness, health, and comfort, are not lost sight of. The terms are low, though the references are very high, being all 'O. F. M.'--'our first men.' THE BOSTON 'CHRISTIAN WORLD.'--We have looked through several numbers of this very various and well-supplied weekly journal, with invariable and increasing interest. It is edited, as we learn, by GEORGE G. CHANNING, a brother of the late lamented Dr. CHANNING, assisted by a number of Unitarian clergymen, and is widely sustained throughout the United States by the patronage and contributions of the members of that religious denomination. It is beautifully printed with a large, clear type, upon paper of a fine color and texture. The mechanical department is in the hands of an artist in his profession, to whose good taste and careful supervision this Magazine has heretofore been much indebted, and for which it here renders its acknowledgments.
