 without a comment, left to the judgment of the reader. Sartain's Magazine. 



This work exhibits great research, as well as an evident taste and talent, on the part of the author, 

 for the study of the history of man, upon zoological principles. It is a book of learning, and full of 

 interest, and may be regarded as among the comparatively few real contributions to science, that 

 eerve to redeem, in some measure, the mass of useless stuff under which the press groans. Chris. 

 Witness. 



This book is characterized by more curious and interesting research than any one that has recently 

 come under our examination. -^ Albany Journal and Register.

 and valuable information, presented in a style at once clear and entertaining, illustrated in the most 

 copious manner with plates of all the various forms of the human race, tracing with the most minute
