⁂ The first is a reprint of the important third edition of 1806; the Additions were offprinted from the substantially revised and enlarged fifth edition and are here published separately for readers who already owned earlier editions. The Additions include chapters on "the checks to population in France" and "the checks to population in England". There are also substantial further thoughts on the poor and the relationship of poverty to civil liberty. The appendix is devoted to a demolition of John Weyland's Principles of Population and Production and James Grahame's An Inquiry into the Principle of Population, both of 1816.
