ACKNOWLEDGMENTS The author wishes to express his grateful appreciation to the Administration of the University of Pennsylvania for providing the leave of absence during which much of the writing of this book was done, to the Wenner-Gren Foundation for Anthropological Research for financial encouragement, and to the American Philosophical Society for the opportunity to utilize its magnificent collection of Darwiniana, including the privilege of quoting from one unpublished letter. For the Anchor edition I have made a few minor changes and drawn attention to my recent study of Edward Blyth. Otherwise the edition remains the same. Loren Eiseley The University of Pennsylvania
