MAN IN NATURE 211

 itself with contrivances which render an animal natu 

 rally defenceless the most formidable of all, and an 

 animal naturally gifted with indifferent locomotive 

 powers able to outstrip all others in speed and 

 range of locomotion. Thus the physiological endow 

 ments of man, while common to him with other 

 animals, and in some respects inferior to theirs, present, 

 in combination with his higher powers, points of 

 difference which lead to the most special and unex 

 pected results. 



In his psychical relations, using this term in its 

 narrower sense, we may see still greater divergences 

 from the line of the lower animals. These may no 

 doubt be connected with his greater volume of brain ; 

 but recent researches seem to show that brain has 

 more to do with motor and sensory powers than 

 with those that are intellectual, and thus that a larger 

 brain is only indirectly connected with higher mental 

 manifestations. Even in the lower animals it is clear 

 that the ferocity of the tiger, the constructive instinct 

 of the beaver, and the sagacity of the elephant depend 

 on psychical powers which are beyond the reach of the

 case in man. Following in part the ingenious 

 analysis of Mivart, we may regard the psychical 

 powers of man as reflex, instinctive, emotional, and 

 intellectual ; and in each of these aspects we shall 

 find points of resemblance to other animals and of
