toward inertia whereas cold and dryness predispose 

 toward activity. 



Thus our final conclusion is that although it is probably 

 possible for selected portions of the white race to become 

 as well adapted to the tropics as are the Javanese for example, 

 it is far from probable that they will maintain a degree of 

 energy and progress equal to that of similarly selected 

 people of the same race in a better cHmate. Always, it 

 would seem, the people who Hve near the chmatic hmits 

 will be at a disadvantage, while those who Hve near the 

 chmatic optima will be the most healthy, energetic and 

 progressive.
