MONKEY FAMILY. 37 



10. The OuRANcsare the only monkeys of the old continent des- 

 titute of ischiatic callosities. The most remarkable species of this 

 genus the OURANG-OUTANG, which inhabits the interior of Borneo, 

 and other large islands of the Indian Ocean, when young 1 , is said, 

 to resemble man more than any other animal. (Plate I- Jig. 4.) 



11. The body is covered with coarse reddish hair, and the face 

 is smooth and bluish ; he sometimes attains the height of seven 

 feet, and possesses great strength and agility; he dwells in the 

 wildest forests and habitually keeps himself upon the trees; he 

 climbs with the greatest rapidity and springs from branch to 

 branch with as much facility and skill as the little monkeys of 

 America, which are often seen in our streets. On the ground, 

 on the contrary, Ourang Outangs walk with difficulty, and are fre- 

 quently obliged to place their hands upon the earth ; we see them, 

 using their long arms to raise themselves up, and throw them- 

 selves forward, very much as a man would use a pair of crutches. 

 It has been ascertained that these animals build themselves huts 

 in lofty trees. It is very difficult to capture them when they have 

 attained adult age, as they defend themselves in the most cou- 

 rageous manner ; but when young they are easily taken ; they 

 then show a good deal of intelligence, attach themselves to those 

 who have care of them, and readily learn to imitate a great many 

 of our actions. 



12. Another species of the genus Ourang, is the Chimpanzee, 

 (Plate \,fig. 5.) which inhabits the interior of Africa, and is also 

 named Jocko. Its arms are not so long as those of the Ourang- 

 Outang, and its forehead is very retreating ; its stature is less 

 than that of man. It lives in troops. 



13. The GIBBONS resemble the Ourang-Outangs in the length 

 of their arms, but their forehead is very receding. They live in the 

 most distant parts of the continent, and archipelago of India, and 

 like the Ourangs inhabit the densest forests. They are not very 

 susceptible of education, and domesticating them seems to make 

 them lose their faculties 



14. The Siamang differs from the other Gibbons in the man- 

 ner in which the first phalanges of the second and third toes are 



10. Have the Ourangs ischiatic callosities or not? When do Ourangs most 

 resemble man? In what part of the world are they found? 



11. What is the size of the Ourang? Does the Ourang-Outang walk with 

 ease in the erect position ? How do they live ? 



12. How is the Chimpanzee distinguished from the Ourang-Outang ? 



13. In what particulars do the Gibbons resemble the Ourang-Oulangs ? 

 In what part of , the world are they found? Are they readily educated ? 



14. How does the Siamang differ from other Gibbons ? What are the habits 

 of the Siamang ? Is the Siamang remarkable for the acuteness of any paj 

 ticular sense ?
