 conditions and problems far more successfully thaa can the native.

 conform to the climate. He should not expect that his internal 

 physiological adjustments will make him independent of his environ-

 quite another." Life in the Tropics will, in the future, certainly be- 

 come more comfortable as well as safer for the white race, but in the 

 light of our present knowledge, acclimatization, in its full and literal 

 sense, is and will remain impossible.
