" My object in the work as a whole is twofold : Firpt. T have thought it de- 

 eirable that ihure should be r<omething ruei^mbliDg a text-book of the facts of 

 Comparative P^iycholog^, to which meu of Bftieuctj, and also mela^hyeicians, may 

 tarn whenever they have occasion to acqu;tint themselves with the parlicuiar 

 level ot intelligence to which thlij or that species of animal attains. My second 

 and much more important oiiject is that of considering ihe tacts of animal iniel- 

 lif^ence in their relation to the theory of descent."— /^/-om t?ie Pr^ace. 



" Unless we are greatly mintaken, Mr. Bomanes^s work will take its place as 

 one of the most attractive volumes of the Inteknational Scientific Setiies. 

 Some persons may. indeed, be di.-*posed to say that it is too atrraclive. that it 

 feeiia the popular taste for the curinus and marvslons without supplying any 

 commeiisnrato di^'cipline in exact scientific reflection ; but the aatnor has, we 

 think, fully Justified nlmself in his modest preface. The result is the ai pearance 

 of a collection of facts wliich will be a real boon to the student of Comparative 

 Psychology, for this is the first attemnt to present systematically well-asBaied 

 observations on the mental lixe of animals." — Saturday JReview. 



''The author believes himself, not without ample caune, to have completely 

 bridged the 8UDp^Bed gap between instinct and reason by the authentic prnoia 

 here mar haled of remarkable intelligence in some of the hioher animals. It is 

 the seemingly conclusive evidence of reasonlcs: powers furnished by the adapta- 

 tion of means to ends in cases which can not be explained on the theory of inher- 

 Itei aptitude or habit."— JVew Fork Sun. 



"The high s^taudingof the author as an original Investigator is a sufficient 

 guarantee tiiat his task has been conscientiously carried out. Ills subject Is one 

 of absiirhing interest. He has collectci and classified an enormous amount of 

 iuforination c<mc«rnin«^ the mental attributes of the animal world. The result 

 is a^*;onlshing. We find marvelous intelligence exfaibired not only by animals 

 which are known to be clever, but by othern seemingly without a glimmer of 

 light, like the snail, for instance. - Some animals display imaginalion, others 

 affection^ and so on. The psychological portion of the diccussion is deeply in- 

 teresting."— iTew York Herald. 



" The chapter on monkeys closes this excellent work, and perhaps the most 

 Instructive portion of it is that devoted to the life-history of a monkey."— iVew 

 Yortcjl^metf, 



*' Mr. Bomanes brings to hl<» work a wide Information and the liest of scientific 

 methods. He has carefully culled and selected an immense mass of data, choos- 

 ing with admirable skill those faers which are really significant, and rtjecting 

 those which lacked sustaining evidence or relevancy. The contents of the volume 

 are arranged with reference to the principles which they seem to bini to estab- 

 lish. The volume Is rich and suggi-'stive. and a model in its way."— Boston i ourier. 



" rt presents the facts of animal intelligence in relation to the theory of de- 

 scent, supplemRUting Darwin and Spencer in tracing the principles which are 

 coiicerned in ihe genesis of m\n6."— Boston I ommonwealtA, 



. " One of the most interesting volumes of the series."— iVisw Tork Christian at

"Few subjects have a greater fascination for the general reader than that 

 vrith which this book is occupied."— ffood Literaiure^ New Tork.
