The Gallery of Illustrious Americans, conducted by Mr. Lester, continues with every number to increase in interest. The work is designed to embrace folio portraits, engraved by Davignon, from daguerreotypes by Brady, of twenty-four of the most eminent American citizens who have lived since the time of Washington. The portraits thus far have been admirable for truthfulness and artistic effect. It may be said that the _only_ published pictures we have, deserving to be called portraits, of the historian Prescott, or Mr. Calhoun, or Colonel Fremont, are in this Gallery. The great artist, naturalist, and man of letters, Audubon, is reflected here as he appears at the close of the battle, receiving the reverence of nations and ages. In the biographical department Mr. Lester has evinced very eminent abilities for this kind of writing. He seizes the prominent events of history and the strong points of character, and presents them with such force and fullness, and happy combination, as to make the letter-press as interesting and valuable as the engraved portion of the work. We are pleased to learn that the Gallery is remarkably successful. No publication of equal splendor and expensiveness has ever before been so well received in this country. The cost of it is but one dollar per number, or twenty dollars for the series of twenty-four numbers. It is now half completed. * * * * * M. Max Schlesinger, author of "The War in Hungary, in 1848-9,"--a work which, from what we read of it in the foreign journals, is much the most striking and attractive of all that have appeared upon its subject in English,--is described in the _Athenæum_, as by birth a Hungarian, by the accidents of fortune a German. For some time a resident in Prague, and more recently settled in Berlin, he has had excellent opportunities of seeing the men and studying the questions connected both in the literary and political sense with the present movement of ideas and races in Eastern Europe. His acquaintance with the aspects of nature in his native land--his knowledge of the peculiar character of its inhabitants, their manners, modes of thought and habits of life--his familiarity with past history--his right conception of the leading men in the recent struggle--are all vouched for as "essentially accurate" by no less an authority than Count Pulszky. It would be an injustice merely to say that M. Schlesinger has given in an original and picturesque way a general view of the course of events in the late war, more complete and connected than is afforded in any account hitherto presented to the public. He has done more: he has enabled the German and English reader to understand the miracle of a nation of four or five millions of men rising up at the command of a great statesman, and doing successful battle with the elaborately organized power of a first-class European state, shaking it to its very foundations, and contending, not without hope,
