106 THE DESCENT OF MAN. [Part 1 



that not a word need here be said. So it is with the lower 

 animals, as has been illustrated by a few examples in' the 

 last chapter. All who have had charge of menageries 

 admit this fact, and we see it plainly in our dogs and other 

 domestic animals. Brehm especially insists that each in- 

 dividual monkey of those which he kept under confine- 

 ment in Africa had its own peculiar disposition and tem- 

 per : he mentions one baboon remarkable for its high in- 

 telligence; and the keepers in the Zoological Gardens 

 pointed out to me a monkey, belonging to the New World 

 division, equally remarkable for intelligence. Rengger, 

 also, insists on the diversity in the various mental charac- 

 ters of the monkeys of the same species which he kept in 

 Paraguay ; and this diversity, as he adds, is partly innate, 

 and partly the result of the manner in which they have 

 been treated or educated. 8 



I have elsewhere 9 so fully discussed the subject of In- 

 heritance that I need here add hardly any thing. A 

 greater number of facts have been collected with respect 

 to the transmission of the most trifling, as well as of the 

 most important characters in man than in any of the lower 

 animals ; though the facts are copious enough with respect 

 to the latter. So in regard to mental qualities, their trans- 

 mission is manifest in our dogs, horses, and other domes- 

 tic animals. Besides special tastes and habits, general in- 

 telligence, courage, bad and good temper, etc., are cer- 

 tainly transmitted. With man we see similar facts in al- 

 most every family ; and we now know through the admi- 

 rable labors of Mr. Galton 10 that genius, which implies a
