put themselves in various attitudes before the mirror; 

 they pressed and rubbed the surface ; they placed their 

 hands at different distances behind it ; looked behind it ; 

 and finally seemed almost frightened, started a little, 

 became cross, and refused to look any longer." So 

 monkeys were tested with a dressed doll, a live turtle, 

 and stuffed snakes, &c. 



The mode and purpose of erection of the hair, feathers, 

 and dermal appendages of animals were the subject of 

 much careful inquiry. Chimpanzees, monkeys, baboons, 

 and many other creatures, were tested in the Zoological 

 Gardens. A stuffed snake taken into the monkey-house 

 caused several species to bristle. When Darwin showed 

 the same to a peccary, the hair rose in a wonderful 

 manner along its back. A cassowary erected its feathers 

 at sight of an ant-eater. 



Every unexpected occurrence was pressed into service. 

 Witness the following anecdote : " One day my horse 

 was much frightened at a drilling machine, covered by a 

 tarpaulin and lying on an open field. He raised his 

 head so high that his neck became almost perpendicular; 

 and this he did from habit, for the machine lay on a slope 

 below, and could not have been seen with more distinct- 

 ness through the raising of the head ; nor if any sound 

 had proceeded from it could the sound have been more 

 distinctly heard. His eyes and ears were directed intently 

 forwards ; and I could feel through the saddle the palpi- 

 tations of his heart. With red, dilated nostrils, he snorted 

 violently, and whirling round, would have dashed off at 

 full speed had I not prevented him." 



We see, too, in this book the results of Darwin's
