ANCIENT TYPES 

 OF MAN 



Illustrated 



From discoveries of ancient human remains 

 made within the last half-century, anthropolo- 

 gists are now able to place in order changes 

 that have taken place in the posture, gait, 

 height, and to some extent the habits of man 

 during a period of at least a half-million years. 

 Prof. Keith, who is one of the foremost investi- 

 gators in this field, tells the story of the various 

 forms which the body of the man has assumed, 

 in a lucid and attractive way.

 subject could write. It must interest every thinking 

 person." — British Medical Journal.
