Pursuing the inquiry further still, we find that the dif- 

 ferent sexes are mutually attracted to each other; that their 

 union is prolific ; that the period of gestation in the female 

 is the same in all ; and that — unlike what happens as to hy- 

 brid animals — instead of stopping short after one or two 

 generations, their offspring continues to be prolific ever after- 

 wards. 



Nor is there any thing difficult to understand, nor con- 

 trary to the analogy of what happens among other animals, 

 in the production of the different varieties of mankind. The 

 Hottentot and the Anglo-Saxon have a closer resemblance 

 to each other than the mastiff and the spaniel. How dif- 

 ferent is the Leicestershire from the Southdown breed of 

 sheep ; and the English dray-horse from the thorough-bred 

 Arabian ! We see these changes actually going on, nay, we 

 actually produce them artificially among our domesticated 

 animals ; and we see them taking place, to a certain extent, 

 even in our own species. The Negroes, taken from on board 

 the captured slave ships and transported to Jamaica, have a 

 different aspect from those who have been for some genera- 

 tions domesticated in the service of the planters. The de- 

 scendants of the Anglo-Saxon race transplanted, within the 

 last two centuries, to other regions of the globe, are already 

 beginning to be distinguishable from those who remain in the 

 parent country by their external appearance, and, even to a 

 greater extent, by their characters and habits. It was ob- 

 served to me by a gentleman who has served his country in 

 important official situations in Europe and on the other side 

 of the Atlantic ocean, that if, in going from England to Italy, 

 he was struck with the comparative passiveness of the 

 Italians, on returning to England from America he found 

 something still more remarkable in the passiveness of the 

 English compared with the excitement and activity observ- 

 able among the citizens of the United States. If in the pre- 

 sent condition of the world, when there is so free an inter- 

 course among its inhabitants, and so constant an intermixture
