This work is principally made up of classified selections from standard writers on ethics. It, of course, lacks unity, and therefore can hardly be called a system of philosophy; but it very well answers the purpose for which it was compiled. Its merit, as a book for schools and general use, consists in the stringent application of moral principles to individual conduct. All those actions and states of mind which clash with morality, are analyzed with much acuteness, and set forth with great directness. * * * * * _Ghost Stones: Collected with a View to Counteract the Vulgar Belief in Ghosts and Apparations. With Ten Engravings from Designs by Darley. Phila.: Carey & Hart. 1 vol. 12mo._ The object of this little volume is clearly enough set forth in the title. It contains twenty stories. The illustrations are graphic, and add to the interest of the wonders described. We notice, however, one omission—the Cock Lane Ghost, in which Dr. Johnson believed. So celebrated a ghost as that should have had a prominent place among the other spectral worthies of the volume. * * * * * _A Progressive German Reader, Adapted to the American Edition of Ollendorff’s German Grammar: with Copious Notes, and a Vocabulary. By G. J. Adler, A. B. New York: D. Appleton & Co. 1 vol. 12mo._ This is an excellent supplement to the German Grammar issued by the same publishers. It is edited by the Professor of the German Language and Literature, in the University of New York. The selections are from some fifty German writers, and are admirably adapted for their purpose. The Vocabulary of German words is an important addition. * * * * * _Views A-Foot: or Europe Seen with Knapsack and Staff. By J. Bayard Taylor. New York: Wiley & Putnam. 2 Parts. 12mo._
