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.
