Note 52 — Chapter I · THE FACTORS.[52]

An outline of the doctrine set forth in the following chapters, was originally published in the Westminster Review for April, 1852, under the title—A Theory of Population deduced from the General Law of Animal Fertility; and was shortly afterwards republished with a prefatory note stating that it must be accepted as a sketch which I hoped at some future time to elaborate. In now revising and completing it, I have omitted a non-essential part of the argument, while I have expanded the remainder by adding to the number of facts put in evidence, by meeting objections which want of space before obliged me to pass over, and by drawing various secondary conclusions. The original paper, with omissions, will be found in Appendix A to Volume I of this work.
