" My object in the work a? a whole is twofold : Firr^t. T have thought it de- 

 Birable that ihcre slioulJ bo i^omething retscmbliiig a text-book of tlie facts of 

 Comparalive Psychology, to which ineu of s^-ieiice, and also melai hysirians, may 

 tiiin whenever they have occasion lo acquiiiit themselves with ihe parlicuiar 

 level ol iiitclligeiice to which tills or that species of auimal attains. My second 

 and much more important object is that ot considerinir the lacts of animal intel- 

 ligence in their relation lo the theory of desceiit." — J'rom the Prejace. 



" Unles.'' we are grea'ly mistaken, Mr. Romanes's work will take its place as 

 one of the most attractive volumes of the International Scientific Sei;ies. 

 Some parsons may. indeed, be disp )geJ to say that it is too attractive, that it 

 feeds ttie popular taste for the curinns and marv?lous withrut supplying any 

 commuMisurate discipline in exact scientific refl(Ction; but the author has, we 

 think, fully justified himself in his modest preface. The result is the a pearinice 

 of a colljctton cf facts wliicb will be a real boon to the student of Comparative 

 Psyclioloiiy, lor this is the first aitemot to present systematically well-assuied 

 observations on the mental liie of animals." — Saturday Remew. 



"The author believes himself, not without ample can»e, to have completely 

 bridged the suopised gap between instinct and reason by the authentic proofs 

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

 the seiMningly conrlusive evidence of ~rc.Tsonin<r powers furnished by the adapta- 

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

 itel aptitude or habit." — New York Sxtn. 



"The high standing of the author as an original investigator is a sufficient 

 guara;itee that his ta>k has been conscientiously carried out. His subject is one 

 of abstirbing interest. He has collected and classified an enormous amount of 

 information Cimcorning the mental attributes of the animal world. The resnlt 

 is a-^'.oiiishing. We find marvelous intelligence exhibited not only by aniir.als 

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

 li^^ht, like the snail, for ii.'stance. Some animals display imagination, others 

 affection, ami so on. The psychological portion of the discussion is deeply in- 

 teresi:ng.''— iVew York Herald. 



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

 instructive portion of it is that devoted to the lile-hisiory of a monkey."— iVtw; 

 York, Time/-: 



" Mr. Romanes brincrs to hi" work a wide information and the best of scientific 

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

 ing with admirable skill those facts which are n-ally significant, and rejecting 

 those w hich 1 icUed sustaining evidence or relevancy. The contents of the volume 

 are arranged with reierence to the principles which they seem to him to estab- 

 lish. The volume is rich and sugg-stive, and a model in its way."— Boston ( ovrier. 



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

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

 coiicerned in the genesis of mmd."— Boston ( ommonwealtit. 



" One of the most interesting volumes of the series,."'— New York Christian at 

 Work. 



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

 vrith which tliis book is occupied."— G'ooaJ Literature, New York.
