NOTES ON THE POPULATION OF JAVA. 49 
fewest, and the mortality greatest, in the town, while the op¬ 
posite state of things prevails in the country, and especially, 
in the more elevated part. All this is in accordance with 
our European experience. Even to the native constitution 
the clear air of the mountain side with the thermometer 
between 70o and 80° would appear to be more conducive to 
health than the close atmosphere of the plain where it is 
between 80° and 90°. Another inference may fairly be drawn 
from this enquiry, limited as it is, that a native population 
under the tropics in the enjoyment of peace, and with a fair 
share of industry, a sufficiency of fertile land, and a favorable 
climate, may increase as rapidly as an European one in a 
temperate climate with similar advantages. 
I am quite sensible of the limited and imperfect nature of 
the statements I am now submitting to the Statistical Society, 
and I furnish them only because 1 am not aware that any 
similar ones for a tropical climate and an indigenous population 
have been laid before the public. Baron Humboldt's, for some 
villages in Mexico, are the nearest approach, but they relate 
not to a purely native, but to a mixed Native and European 
population.
