DESCENT OF MAN FROM SOME LOWER FORM. 163

 pies black, no matter what was the color of the bitch " ; 

 but then Bedlamite "had a preponderance of black in

Descent ^ an m ^ ne rudest state in which he now

 more widely than any other highly organized form ; and 

 all others have yielded before him. He manifestly owes 

 this immense superiority to his intellectual faculties, to 

 his social habits, which lead him to aid and defend his 

 fellows, and to his corporeal structure. The supreme 

 importance of these characters has been proved by the 

 final arbitrament of the battle for life. Through his 

 powers of intellect, articulate language has been evolved ; 

 and on this his wonderful advancement has mainly de- 

 pended. As Mr. Chauncey Wright remarks: "A psy- 

 chological analysis of the faculty of language shows that 

 even the smallest proficiency in it might require more 

 brain-power than the greatest proficiency in any other

 man, excepting language, dates from before the dawn of
