if in some of his senses he excels many, in this respect 

 also he is inferior to others ; and if in his general adapt- 

 ations he is far superior, there are special instances in 

 which he is greatly inferior. As a mere animal, then, 

 man, like other animals, has his place in nature. It 

 may be higher, but this is difference in degree not 

 difference in kind ; and it would be setting aside all 

 philosophy in science to shrink from applying to him 

 the same methods of research that are applied to the 

 other forms that constitute with him the great brother- 

 hood of vitality. 



And yet, influenced by preconceptions as to man's 

 origin and destiny, there are zoologists who would

 gether of its own kind, in their schemes of classifica- 

 tion, forgetful that the essentials of existence axe the 

 same to man as to other living beings, and forgetful 

 also that almost all the great physiological laws and 

 therapeutic considerations of modern times have been 

 arrived at more perhaps from the investigation of 

 vital phenomena in the lower animals than from their 

 study in the human race. The truth is, the immense 

 progress recently made in biological science has arisen 

 chiefly from researches among the lower forms of 

 vitality, and any attempt to separate man from the 

 general scheme of life is stultified at once, and alto- 

 gether apart from scientific considerations, by the
