Excerpt from The Principles of Political Economy: With Some Inquiries Respecting Their Application, and a Sketch of the Rise and Progress of the Science Other engagements, while they prevented the publication of a new edition of this work, which has been long out of print, afforded time for additional observation and consideration; and these have far ther strengthened the conviction, that the principle on which we proceeded in drawing up the edition of 1830 is, on the whole, the best. In this edition, consequently, a still greater extension has been given to the practical parts, or to inquiries respecting the real or probable influence of different systems of economical legislation, over the wealth and wellbeing of society. The work, indeed, is no longer to be regarded as a mere attempt to trace and exhibit the principles of Political Economy; but also as an attempt, however imperfect, to exhibit their more important applications.
