PREFACE TO THE SECOND, REVISED AND 

 ENLARGED, GERMAN EDITION 



THE book " Der Bau der Menschen " made its first appearance in 

 the year 1887 in the form of an academic treatise, intended 

 only for a limited circle of readers. There were no illustrations, 

 and the method of treatment of the material was very brief, 

 indeed, in many parts a mere sketch of the subject was given. 

 Notwithstanding this, I received letters and questions which 

 showed me that my treatise had awakened interest in a circle of 

 readers wider than that for which it was originally intended, and 

 I therefore decided to reissue it in a more complete form. 



The leading ideas are the same, although I think I may 

 claim to have improved upon the manner and form in which 

 they have been carried out. The large number of illustrations 

 which accompany the text, as well as the wider foundation of 

 comparative anatomy and ontogeny on which the subject rests, 

 have, I hope, both made it more intelligible and greatly increased 

 its usefulness. 



An index has been added, giving a review of the material 

 dealt with, and also, for the use of the lay reader, a glossary of 

 the zoological tetms employed. 



I must express my hearty thanks to my publisher for the 

 friendly assistance he has shown me. 



It is my earnest hope that this work in its new form may 

 once more win recognition, since it aims at assisting man to 

 know himself. 



THE AUTHOR.
