THE ORIGIN OF THE ARYANS. By Dr. Isaac Taylor. 



With numerous Illustrations. [Head;/. 



The last ten years have seen a revolution in the opinion of scholars as to the 

 •region in which the Aryan race originated, and theories which not long ago 

 were universally accepted as the well established conclusions of science now 

 hardly find a defender. The theory of migration from Asia has been dis- 

 placed by a new theory of origin in Northern Europe. In Germany several 

 works have been devoted to the subject, but this is the first English work 

 which has yet appeared embodying the results recently arrived at by philo- 

 logists, archaeologists, and anthropologists. This volume affords a fresh and 

 highly interesting account of the present state of speculation on a highly 

 interesting subject.
