34 THE MAX-LIKE APES. i 



In all, the fore limbs are terminated by hands, 

 provided with longer or shorter thumbs; while 

 the great toe of the foot, always smaller than in 

 Man, is far more movable than in him and can be 

 opposed, like a thumb, to the rest of the foot. 

 Xone of these apes have tails, and none of them 

 possess the cheek-pouches common among mon- 

 keys. Finally, they are all inhabitants of the old 

 world. 



The Gibbons are the smallest, slenderest, and 

 longest-limbed of the man-like Apes: their arms 

 are longer in proportion to their bodies than those 

 of any of the other man-like Apes, so that they 

 can touch the ground when erect; their hands are 

 longer than their feet, and they are the only An- 

 thropoids which possess callosities like the lower 

 monkeys. They are variously coloured. The 

 Orangs have arms which reach to the ankles in 

 the erect position of the animal; their thumbs and 

 great toes are very short, and their feet are longer 

 than their hands. They are covered with reddish 

 brown hair, and the sides of the face, in adult 

 males, are commonly produced into two crescentic, 

 flexible excrescences, like fatty tumours. The 

 Chimpanzees have arms which reach below the 

 knees; they have large thumbs and great toes; 

 their hands are longer than their feet; and their 

 hair is black, while the skin of the face is pale. 

 The Gorilla, lastly, has arms which reach to the 

 middle of the leg, large thumbs and great toes,
