822 THE MENTAL CAPACITIES AND 



them, and of shaping their actions into some accordance 

 therewith as well as the range and complexity of the 

 Emotions which they are capable of feeling and plainly 

 manifesting on different occasions. 



In regard to the Cai, or Weeper Capuchin, one of the 

 long-tailed New World Monkeys, 



P. M. Duncan (Cassell's " Nat. History," p. 184) quotes Rengger 

 to the effect, that when he first gave eggs to these animals " they 

 smashed them, and thus lost much of their contents; afterwards they 

 gently put one end against some hard body and picked off the bits 

 of shell with their fingers. After cutting themselves only once with 

 a sharp tool they would not touch it again, or would handle it with 

 the greatest care. Lumps of sugar were often given them wrapped 

 up in paper, and Eengger sometimes put a live wasp in the paper. 

 After this had happened once, they always first held the packet to 

 their ears to detect any movement within." 



The same writer in his account of a female Chacma, 

 or Pig-tailed Baboon (loc. cit., p. 146), says : 



" She not only adopted young Monkeys of other species, 

 but stole young dogs and cats, which she continually carried 

 about. Her kindness, however, did not go so far as to share her 

 food with her adopted offspring. An adopted kitten scratched this 

 affectionate and selfish old thing, who certainly had a fine intellect, 

 for she was much astonished at being scratched, and immediately 

 examined the kitten's feet, and without more ado bit off the claws ! " 



The same writer also cites (loc. cit., p. 184,) the follow- 

 ing remarkable instance of Intelligence : 



" Formerly one of the large Monkeys in the Zoological Gardens 

 had weak teeth, and he used to break open the nuts with a stone. 

 Mr. Darwin was assured by the keepers that this animal, after 

 using the stone hid it in the straw, and would not let any other 

 Monkey touch it." 



The development of Intelligence, Emotion, and Voli- 

 tion, which becomes so obvious in lower Quadrumana,
