FOOT-HA*TDED AND HAND- WINGED VERTEBRATES. 29 



41. The races of men may also be subdivided into va- 

 rieties. Each nation has characteristics which are some- 

 times very marked. Thus the English and the Irish can 

 ordinarily be readily distinguished at a glance. The 

 Jews also have always been remarkably distinct from 

 other nations. Then, too, we occasionally see an indi-

Questions. What is said of the machinery in different animals? 

 What of the variety of motion in the foot of man, and in his hand ? 

 What of the apparent simplicity of the hand as an instrument ? What

 tween the varieties of the human race, and the varieties in animals. 

 What is said of national and family varieties ?

42. THE sub-class which I call Pedimana is termed, 

 in the common classifications of zoologists, the order 

 Quadrumana, four-handed animals. It is the ape and 

 monkey-tribe. I have already spoken in Chapter II. of 

 the capabilities of the hand of man as an instrument. 

 If we compare them with the very limited capabilities of 

 the hand of the ape or monkey, we must agree with Sir 

 Charles Bell, who says that " we ought to define the
