The results of Professor Groos's original and acute investiga- 

 tions are of peculiar value to those who are interested in psychol- 

 ogy and sociology, and they are of great importance to educators. 

 He presents the anthropological aspects of the subject treated in 

 his psychological study of the Play of Animals, which has already 

 become a classic. Professor Groos, who agrees with the follow- 

 ers of Weismann, develops the great importance of the child's play 

 as tending to strengthen his inheritance in the acquisition of adap- 

 tations to his environment. The influence of play on character, 

 and its relation to education, are suggestively indicated. The 

 playful manifestations affecting the child himself and those affect- 

 ing his relations to others have been carefully classified, and the 

 reader is led from the simpler exercises of the sensory appajatus 

 through a variety of divisions to inner imitations and social play. 

 The biological, aesthetic, ethical, and pedagogical standpoints re- 

 ceive much attention from the investigator. While this book is 

 an illuminating contribution to scientific literature, it is of eminently 

 pracdcal value. Its illustrations and lessons will be studied and 

 applied by educators, and the importance of this original presenta- 

 tion of a most fertile subject will be appreciated by parents as well 

 as by those who are interested as general students of sociological 

 and psychological themes.
