Islands, has vastly increased, through the discovery that formerly 
dwarf races were widely distributed, evidence of their existence 
having been obtained in North Africa, Sicily, Switzerland, and: 
the Pyrenees in the Old World, and in Central America in the

In editing this work, I have spared no pains to bring it up 
to the standard of English requirements. In the course of the 
revision a free rendering, rather than a translation, of the original 
German has been deemed in many places desirable; and para- 
eraphs dealing with incidental and controversial topics have 
been for the most part put into small type. Important altera- 
tions and intercalations are enclosed in square brackets, and 
for these I hold myself responsible. My triend Professor 
Arthur Thomson of Oxford has done me the great service of 
looking through the proof-sheets, and to him and my friends 
Dr. Forsyth-Major and Mr. Oldfield Thomas, I tender my sincere 
thanks for advice wpon special topics.
