The Orang-utan is not the only man-shaped Ape of the forests and jungles of the great Asiatic 
Islands, for there are several others to be found there, and which also live on the main land, from 
Malacca far away to the north in Assam ; southwards, in the peninsula of Hindostan, and in South 
China. 
They are less human-looking than the red Orangs, and they are smaller and more slender, but 
when they walk for a short distance erect, with the arms above the head balancing the body, their 
resemblance to a small and hairy “lord of creation” is considerable. A veiy slight glance dis- 
tinguishes them from the Orangs ; they have straight backs, small heads, large eyes, rather prominent 
■chins, very long fore-arms, and their fingers reach the ankle in some, and the ground in others. 
Moreover, the Orangs sit upon a surface of hair, and these are furnished with a hard padlike seat 
which is bare, and is called a callosity, but they have no tail. They can run. 
These long-armed Apes have a number of names, but as a whole they are called Gibbons ; and 
as their outside and inside differences and distinctions from the Orangs are considerable and more 
than those of the kinds of Orangs between themselves, they are grouped into a separate genus. The
