Purity of Hie Air in different parts of Colombo. 
A few determinations of the purity of the air 
in different parts of Colombo were made, based 
upon the proportion of carbon dioxide, or, as it is 
popularly called, carbonic acid, present. 
The normal amount of carbonic acid in pure air 
is 4. parts per 10,000 by volume. Some writers 
state that the range of carbonic acid in normal 
air is from 2 to 5 volumes per 10,000. 
In inhabited rooms where the carbonic acid 
exceeds 6 volumes per 10,000, the organic matters 
given off from the lungs by respiration become 
appreciable to the sense of smell, and one then 
becomes aware that one is breathing a foul 
atmosphere.
