VI PREFACE. 



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. K. Angus 

 Smith, and Messrs. E. 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.
