CONCLUSIONS. 181 



animal and vegetable food in the several regions, might be 

 expected to involve, with his corresponding customs and 

 modes of life, a difference in the physical constitution of 

 man, which would contribute to augment any primeval dif- 

 ferences. It could not indeed be expected, that a people 

 constantly subjected to cold, like the people of the North, 

 and living almost exclusively on fish, which they cannot 

 obtain without great toil and peril, should present the same 

 characteristics, either bodily or mental, as those who idly 

 regale on the spontaneous bounties of tropical vegetation.
