_Southern Literary Messenger_.--We have received the last number of this beautiful and valuable Magazine, and take great pleasure in expressing the delight with which we have perused its contents. It is certainly the best Magazine now published in the Union, and is an honor to Southern literature and talent. The present number like its predecessors, is replete with 'pearls, and gems, and flowers,' and fully sustains the elevated character of the work. The Critical Notices are peculiarly meritorious and sensible. The Messenger is now under the editorial guidance of Edgar A. Poe, a gentleman highly distinguished for his literary taste and talent. From the Fincastle Democrat. _Southern Literary Messenger_.--We have been furnished, by the worthy publisher, with the February number of this "best of American periodicals," as it is said to be by a distinguished Northern contemporary. This number is pronounced, in all of the many notices which we have seen, to be the best of the fifteen that have been published; of this we are not competent to decide, not having been favored with the previous numbers; but, be it as it may, we cheerfully coincide in the annexed sentiment of the editor of the Pennsylvanian:--"If it is not well supported by our brethren of the South, no faith is to be placed in their sectional feeling; _it is vox et præterea nihil_." From the U. S. Gazette. The Southern Literary Messenger for March, full of good matter, is at hand--delayed with a view of giving the whole of Professor Dew's address. We miss the racy and condemnatory criticism that distinguishes the work, and which has been favorable to the production of good books. We who publish no volumes, look with complacency upon severe criticism. From the Richmond Compiler. The writer of the following judicious article, has performed a task for which he is entitled to our thanks. A want of time and a lack of the proper talent for criticism, have prevented us from giving our opinion at length upon the last number of the Messenger; and this sketch saves us the labor. We accord with most of the writer's positions, and are pleased with the good sense, moderation and delicacy with which he has discharged the office of censor. Criticism, to be useful, must be just and impartial. This is both.
