Preface 



vu 



Otherwise expressed, we may say that : Just as surely as 

 we find among the wild animals the germs or beginnings of 

 man's material make-up, so surely may we find there also 

 the foundations and possibilities of what he has attained to 

 in the world of mind. This thought lends new interest to 

 the doings of animals in their home-life, and I have sought 

 among these our lesser brethren for evidences of it— in the 

 rudiments of speech, sign-language, musical sense, esthet- 

 ics, amusements, home-making, social system, sanitation, 

 wed-law, morals, personal and territorial property law, etc. 



As much as possible, I have kept my theories apart 

 from my facts, in order that the reader may judge the 

 former for himself.
