bles, or is likely to be any very near relation of, the lady you 

 have invited to go with you and inspect it. The orang outang 

 is a far more intelligent animal than the gorilla, but its skull 

 (Fig. 14) does not give one a high idea of its intellectual 

 character. 



Man is two-handed, and his hands are capable of executing 

 a great deal of what his mind can conceive. The four hands of 

 the monkey are strong and flexible, good for climbing, picking 

 fruit, and conveying it to his mouth. . Man walks erect on two 

 feet, with straight legs, and muscular developments on the back 

 of the pelvis and leg to enable him to maintain the upright 

 position. Monkeys have four hands, admirable for climbing, 

 and they stand on their hind legs when trained to do so, but 

 awkwardly, with bent knees, and resting on the outer edge of 

 the posterior hands. The foot, or hinder hand, of the orang

has very little resemblance to the foot of man. The head of 

 man, balanced on its centre, with its eyes looking forward 

 horizontally, as well as the form and comparative size of the 

 head, make him strikingly different from all the animal creation. 

 The human brain is mostly above the orbit of the eye, that of 

 the gorilla is mostly below it; an average European child, four 

 vears old, has a brain twice as large as that of the adult gorilla.
