THE VARIATION OF

ANIMALS AND PLANTS

UNDER DOMESTICATION

BY

CHARLES DARWIN, M.A., F.R.S., ETC.

IN TWO VOLUMES

VOLUME I.

PREFACE TO THE SECOND EDITION.

During the seven years which have elapsed since the publication in 1868 of the first edition of this Work, I have continued to attend to the same subjects, as far as lay in my power; and I have thus accumulated a large body of additional facts, chiefly through the kindness of many correspondents. Of these facts I have been able here to use only those which seemed to me the more important. I have omitted some statements, and corrected some errors, the discovery of which I owe to my reviewers. Many additional references have been given. The eleventh chapter, and that on Pangenesis, are those which have been most altered, parts having been re modelled; but I will give a list of the more important alterations for the sake of those who may possess the first edition of this book.
