PREFACE TO SECOND EDITION
The present edition is a reprint of the first, with a few verbal corrections and the alteration of some erroneous or doubtful statements. Of these latter the following are the most important:—
P. [30]. The statement as to the fulmar petrel, which Professor A. Newton assures me is erroneous, has been modified.
P. [34]. A note is added as to Darwin's statement about the missel and song-thrushes in Scotland.
P. [172]. An error as to the differently-coloured herds of cattle in the Falkland Islands, is corrected.

PREFACE TO FIRST EDITION
The present work treats the problem of the Origin of Species on the same general lines as were adopted by Darwin; but from the standpoint reached after nearly thirty years of discussion, with an abundance of new facts and the advocacy of many new or old theories.
