Mr. MAXWELL'S Speech, before the Virginia Historical and Philosophical Society, at its late annual meeting, another eloquent eulogy upon the lamented MARSHALL. Virginia seems to be taking the most serene delight in wreathing garlands around his tomb, and this is one of the most verdant, and promises to be one of the most enduring. It is short, but breathes eloquently forth a spirit which will impress it upon the minds and memories of hearers and readers. It is a high compliment to the MESSENGER, and a pregnant proof of the estimation into which that journal has worthily grown that it is made the medium of conveying such productions to posterity. But the most valuable paper in the number is an Address on the influence of the Federative Republican System of Government upon Literature, and the Development of Character, by Professor Dew. We have never perused a more able literary essay than this address. The author traverses the whole field of literature, and draws from the stores of antiquity lessons for the improvement of his own countrymen in literature, art, and politics. We commend it to the perusal of every American. Then follow "_Critical Notices_." These are written by POE. They are few and clever. The sledge-hammer and scimetar are laid aside, and not one poor devil of an author is touched, except one "Mahmoud," who is let off with a box on the ear for plagiarism. The review of "Georgia Scenes" has determined us to buy the book. The extracts are irresistible. The merit of this number consists in its solidity. The same amount of reading, of a similar character, can certainly no where and in no other form be furnished the reader on the same terms. It is our duty no less than our interest to sustain 'the Messenger.' {343} From the Norfolk Herald. _Southern Literary Messenger_.--No. 4, Vol. 2, of this Journal is just issued, and contains 16 pages of matter over and above its usual quantity--that is, it contains 80 closely printed pages in place of 64, its promised amount. A very slight inspection will convince any one at all conversant in these matters that the present number of the Messenger embraces as much reading matter (if not considerably more) than four ordinary volumes, such for example, as the volumes of Paul Ulric or Norman Leslie. Of the value of the matter, or rather of its value in comparison with such ephemera as these just mentioned, it is of course unnecessary to say much. Popular opinion has placed the Messenger in a very enviable position as regards the Literature of the South. We have no hesitation in saying that it has elevated it immeasurably. To use the words of a Northern contemporary "it has done more within the last six months to refine the literary standard in this country than has been accomplished before in the space of ten years."
