The Knickerbocker, or New-York Monthly Magazine, is a Collection of Magazines of New-York in May 1844. These magazine are very popular at that time. The book describes that article has been compiled from the different works of THOMAS CARLYLE, and embodies all he has written, or at least published, about Napoleon Bonaparte. We offer it in the absence of a more elaborate work on this subject, which we hope one day to see from the pen of this gifted and earnest writer. It is a glimpse of the insight of the clearest-headed Seer of our age, into the noisiest great man of the last, about whom we listen with pleasure to each new voice, perhaps critically and doubtingly, yet for our own part colored by that absorbing, painful interest, which induced us when a boy to close the book which first told us of his doings, after having traced his meteoric flight to the 'monster meeting' at Moscow, unable to proceed to the catastrophe; and it was months before we could bring ourselves to read on, of the heroism which charmed, or the glitter which dazzled us, to its final chaos and night. On Napoleon's right to the title great, the character of his greatness, and what would be left if the smoke-clouds, battle-glory and so on were torn away, we will offer but a few words. Of the title in its best sense but few now believe him worthy, perhaps no thinker or reflecting man.
