58 Actual Races in History \ 



not prejudice the identity of their canine species, 

 in the strict scientific sense of that term, as ex- 

 plained before (No. 52, 53). — I take it, you under- 

 stand quite well how this comparison between man 

 and the brute creation comes to be made so con- 

 stantly; and I need not apologize for instituting a 

 scientific comparison between them. It is because 

 of the analogy that exists between them, since all 

 are in the one genus of living organisms having 

 animal life. But, as to their respective species, man 

 is specifically a rational being; whereas the rest are 

 irrational, or brute. 



62. It is to be observed that these extreme 

 varieties in stature among men are not separated by 

 any wide chasm between, as is the case in almost 

 every respect between man and the ape; where no 

 scientific trace of a bridge between, which still con- 

 nects them, or of a common point behind whence 

 they could have diverged — no " link," as it is termed 

 — has ever been detected. Here every size between 

 the extremes in mankind is represented by existing 

 races, all thus merging into one another insensibly. 

 The same holds with regard to colors. There are 

 extreme colors among men, as there are in species 

 of the animal kingdom. But every shade between, 

 of black, white, yellow, red, is also exemplified. 

 The blending and mixing of hues and tints is

 horses, varying as they do from one extreme of
