The Expression of the Emotions 

 in Man and Animals. 



By CHARLES DARWIN, F. R. S., Author of the "Origin of Species," etc., etc. 



"Whatever one thinks of Mr. Darwin's theory, it must be admitted that his great 

 powers of observation are as conspicuous as ever in this inquiry. During a space ot 

 more than thirty years, he has, with exemplary patience, been accumulating informa- 

 tion from all available sources. The result of all this is undoubtedly the collection of a 

 mass of minute and trustworthy information which must possess the highest value, 

 whatever may be the conclusions ultimately deduced from it." — London Tunes, 



" It is almost needless to say that Mr. Darwin has brought to this work vast stores 

 of erudition, accumulated treasures of careful observation, and all the devices of an 

 acute and fertile ingenuity; for these are qualities which are conspicuous in all he 

 writes. But it may be as well to add that the book is very, attractive even to general 

 readers. It is comparatively light and easy reading, full of amusing anecdote ; and the 

 illustrations, whether due to the sun's rays or to the engraver's point, are excellent." — 

 Guardian. 



" Those of our readers who know the charm of Darwin's former works, how he 

 leads his readers on to his conclusions in the clearest and most attractive English, will 

 experience more than their usual treat when they sit down to this book. Never was 

 more truly realized the saying about men laboring and others entering into the fruit of 

 their labors. The illustrations are excellent, and recourse has been had to photographs 

 in rendering the more teHing of the physiognomical expressions. Even the most an- 

 tagonistic of anti-Darwinians will not hesitate to admit how much he has learned from 

 a careful study of the work before us." — Science Gossip.
