The first edition of this work was published in 1854, and, although a large one, has been long out of print. Many inquiries having been made for it since the recent lamented death of the translator, the publishers have determined to offer a second edition to the public, and have been advised to give it a place in their “English and Foreign Philosophical Library.” It is an exact reprint of the first edition, and they trust it will be received with equal favour.

London, June 1881.
