formed. Each idea arises out of former ideas, and 

 gives birth to new ones. The structure, and quality of 

 the higher organism are the result of "Variation," 

 brought about, in the same method, from the same 

 causes, that produce other organic variations. The law 

 of variation in the structure, as said before, of organ- 

 isms, upon which natural selection operates to produce 

 new species, is rather obscure. It is thought, that at 

 certain periods, not definitely determined, especially 

 for animal organisms, variation appears by a law of 

 rhythm, in procreation. Sometimes, especially in low 

 orders of vegetation, this law produces, at once, a new 

 species. Yet the influence of environment, as well as 

 inherency, is known to affect the offspring very de- 

 cidedly. Max Meyer says that the ganglionic centers 

 of the brain have the power to throw out new fibres 

 and thus form new reflexes, and these are variations. 



RACE DIFFERENCES. The variation in structure that 

 enables one man to comprehend more numerous and 

 obscure facts, and by virtue of former experiences, 

 commonly called education, to draw more accurately 

 the correct conclusions from them, than another man 

 is capable of doing, is what is called the better mind. 

 The ampler this responsiveness, the greater the knowl- 

 edge. The known to him, is just what his nervous 

 structure enables him to absorb from the outer realm, 

 and co-ordinate into ideas. The domain of the know- 

 able, is just in proportion to the development of this 

 correspondence. Thus structure and function go hand 

 in hand. They are simultaneous in development. 



The colored children in schools are said to be quite 

 as apt in the elementary studies as the white children, 

 and in many cases, more readily absorb the teachings. 

 But, when the higher branches are reached, the white
