PREFACE TO SECOND EDITION 



The publication of the second edition of this book has 

 ena])led tlie author to make a few improvements in the 

 text and to acUl at the end of C^iapter IV, a brief note 

 upon the family as a factor in social evolution. This 

 Iniman institution has received undue emphasis as the 

 original form of association. It seemed well to cite a 

 few opinions upon this point. 



Several errors which appeared in the first edition have 

 l)een corrected. In a few cases the inadvertent omission 

 of quotation marks and credits has been rectified. The 

 author wishes to thank Professor M. M. jMetcalf for 

 calling- attention to these infelicities. The helpful criti- 

 cism of other details has been also appreciated by the 

 author.
