Excerpt from Vitamines Essential Food Factors Gan/gen. But what is there in the air that is so essential to burning? The chemist tells us that it is the oxygen. This gas is present in the-air to the extent of about twenty per cent. If a sam ple of air be taken and the oxygen removed from, it, your paper will not burn, nor will anything else that ordinarily burns in the air. If, on the other hand, you take your burning paper or lighted candle, and thrust it into a jar containing the removed oxygen, the paper or candle will burn with a brilliancy that dazzles the eye.
