SAMUEL BAILEY, whose "Essays on the Pursuit of Truth and on the Progress of Knowledge," "Essays on the Formation and Publication of Opinions," &c., have been largely read in this country, has just published a volume entitled, "The Theory of Reasoning, with Comments on the Principal Points of Scholastic Logic." * * * * * MAJOR POUSSIN'S "United States, their Power and Progress," a translation of _La Puissance Americaine_, by Edmund L. Du Barry, U. S. N., has been published in a large octavo of about five hundred pages, by Lippencott, Grambo, & Co., of Philadelphia. We take the opportunity to give some account of the author.

After a short residence in New-York he proceeded to Philadelphia, where he expected to meet with some encouragement in his profession as an engineer. Here he became acquainted with Mr. Fairman, the engraver, and worked for him a few months with advantage, boarding meanwhile at a French house, into which the landlady received him in consideration of the devotion of his leisure to the instruction of her children.
