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.

Excerpt from Vitamines Essential Food Factors
This book is a popular presentation of a subject which concerns every one of us; for vitamines are substances, as yet ill-defined, whose presence in food is essential to our well-being: their absence makes life impossible. And what more pressing problem to-day than that of food!
The entire subject is not more than ten years old - we ate vitamines before 1910, but we were not aware of it - yet the mass of work that has been done during these few years has added enormously to our knowledge of the science of nutrition. But the results of such research work are securely hidden from the gaze of the layman by their publication in technical journals, and through the use of language which is well-nigh meaningless to the man who is not a food specialist. The aim of the present volume is to reinterpret, in terras of our everyday tongue, the language of the research worker. Though "popular," the book is, I believe, a very faithful account of the labors of our scientific friends.
Experience has taught me that by far the best method of approach to an entirely new subject is the historical or evolutionary.
