 between the sixth and tenth centuries. There "was no 

 great racial change made, then, when the Danes con- 

 quered the country in the early part of the eleventh 

 century, or when William the Conqueror brought over 

 his Normans of the same stock in the latter part. 



The main point we wish to bring out is that England

 entered the blood of many Nordic Aryans who differed 

 from each other in some degree. It makes no difference

 the exactitude of the racial history. That is not essential 

 and one need not quibble about it. The fact remains that 

 the English and Scotch have a generally high civic value 

 and are extremely variable. They produce genius and 

 they produce wretchedness as the natural result of the 

 recombination of these variations. Selections made from 

 the best of these segregates have given the United States 

 names of which one may well be proud ; selections made 

 from the other extreme have furnished several of the 

 undesirable strains described previously under the 

 pseudonyms Nam, Juke, etc. 



The Irish, on the other hand, and the same might be 

 said of some other isolated types, are; much purer 

 from the genetic standpoint. Is there not some reason 

 for attributing to this comparative purity, to this lack

A case similar to that of England and Scotland might 

 be made out of France and for Germany, though France 

 has perhaps a greater proportion of the blood of the
