Harper and Brothers have reprinted SYDNEY SMITH'S posthumous Lectures entitled _Sketches of Moral Philosophy_, which is introduced with a commendatory letter by Lord Jeffrey, written but a few days before his death, wherein he says that these Lectures "will do their author as much credit as any thing he ever wrote, and produce on the whole a stronger impression by the force and vivacity of his intellect, as well as a truer and more engaging view of his character than what the world has yet seen of his writings. The book seems to me to be full of good sense, acuteness, and right feeling--very clearly and pleasingly written--and with such an admirable mixture of logical intrepidity, with the absence of all dogmatism, as is rarely met with in the conduct of such discussions." The versatile author discusses a great variety of topics, slenderly connected it is true, with Metaphysics or Moral Philosophy, and on this account has left a far more readable volume, than if it had been rigidly devoted to the questions which it professes to treat. His remarks are always lively, pointed, and apposite, betraying a familiar knowledge of the world, and a quick perception of the bearing and character of current events, while their caustic wit is usually attempered with an inexhaustible fountain of good humor. We have received _The Plough, the Loom, and the Anvil_, volume 2d, from the veteran editor of whose zeal and ability in maintaining the doctrine of "harmony" and mutual dependence between all the great branches of domestic industry, it affords abundant evidence.
