522 THE AMERICAN NATURALIST. [Vor. XXXIV. 
tables are furnished in the appendixes to the volume. The hair is 
given particular prominence in the classification of races according 
to morphological characters. Confidence is expressed in the ability 
of Europeans to colonize the Tropics, though little evidence is 
adduced in support of the opinion. For the first time, we believe, 
in a general work attention is directed to the nervous susceptibility 
of savages, which some students of primitive culture regard as an 
important factor in the development of religion. 
* Ethnic Characters," including language, the arts, religion, the 
family, and social life, are treated in four chapters that seem all too 
brief to the serious student. Indeed, the entire volume reminds the 
reader of Tony Weller's comment upon brevity in letter writing. 
Half the book is devoted to Races and Peoples. Dr. Deniker 
modifies somewhat his classification of the races of mankind in gen- 
eral, published in 1889, and now divides the species into twenty-nine 
races, which in turn are separated into seventeen groups, by taking 
into account other characters than somatic alone. The ancient in- 
habitants of Europe are passed over with but brief mention; the 
Aryan question is dismissed as unanswerable and no longer of any 
consequence in anthropology. His well-known scheme of classifica- 
tion of the present races of Europe into six primary and four second- 
ary races is given in briefer form than in previously published papers 
of the Anthropological Society of Paris. The few paragraphs upon 
the archeology of Asia show that the subject is becoming better 
known and sheds light upon the ancient history of Europe. The 
complete account of the migrations of Asiatic tribes within historic 
times cannot yet be written. So also we can only discern in a gen- 
eral way the elements furnished by the eleven races into which the 
peoples of the continent are divided. 
Dr. Deniker accepts quaternary man in North America as estab- 
lished by the discoveries at Trenton, Little Falls, Minnesota, etc. 
The mounds of North America are ascribed to the Indians. The 
modern tribes are considered by ethnographic provinces rather than 
by groups based upon somatic characters or ethnic traits. 
_ The author is certainly correct in his belief “that even profes- 
sional anthropologists will be able to consult" this work * profit- 
ably.” While ethnic maps would have added much to the value of 
the book, and though there are statements of fact and deductions 
susceptible to criticism, yet it presents a masterly summary of an 
extensive and intricate subject. FRANK RUSSÉLL.
