INTRODUCTION. |

WHEN on board H.M.S. 'Beagle,' as naturalist, I was much struck with certain facts in the distribution of the
inhabitants of inhabitants of 1859 1860 |
organic beings inhabiting 1861 1866 1869 1872 |
South America, and in the geological relations of the present to the past inhabitants of that continent. These
facts facts 1859 1860 | facts, 1861 1866 1869 1872 |
seemed to me seemed to me 1859 1860 |
as will be seen in the latter chapters of this volume, seemed 1861 1866 1869 1872 |
to throw some light on the origin of species— that mystery of mysteries, as it has been called by one of our greatest philosophers. On my return home, it occurred to me, in 1837, that something might perhaps be made out on this question by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it. After five years' work I allowed myself to speculate on the subject, and drew up some short notes; these I enlarged in 1844 into a sketch of the conclusions, which then seemed to me
probable: probable: 1859 1860 1861 1866 1869 | probable; 1872 |
from that period to the present day I have steadily pursued the same object. I hope that I may be excused for entering on these personal details, as I give them to show that I have not been hasty in coming to a decision. |

My work is now
nearly nearly 1859 1860 1861 1866 1869 | (1859) nearly 1872 |
finished; but as it will take me

more years to complete it, and as my health is far from strong, I have been urged to publish this Abstract. I have more especially been induced to do this, as Mr.
