larly to prepare myself for the present enquiry, by the examination of the more important Museums in France and Italy, and of some of those in Germany and Switzerland.
Among many friends who have aided me in various ways, my thanks are more particularly due to Mr. A. E. Dobbs for revising the proofs; to Dr. R. Angus Smith, and Messrs. R. D. Darbishire, John Evans, J. F. Philips, A. W. Franks, Worthington, G. Smith, and Marcus M. Hartog, for assistance of various kinds in the letterpress. For the use of many wood blocks, I have also to thank Messrs. Cheadle, Pengelly, Gardner, Greenwell, Evans, Mello, Franks, Parker, Williams and Norgate, General Lane Fox, and Professor Daniel Wilson, as well as the Councils of the Geological Society of London, of the Society of Antiquaries, and of the Plymouth Institution. And lastly, I have to thank Mr. Rowe, a young and promising artist, for the care with which he has represented the groups of Eocene, Meiocene, and Pleiocene life.
In laying this book before my readers, I am conscious of its many defects, arising to some extent from the nature of the subject, and from the swiftness with which our knowledge of Early Man is being enlarged by new discoveries.
