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.
