CASES and mixtures of them are so common and so much a part of every-day existence that they become so taken for granted that their individual characteristics and idiosyncrasies rarely become of curiosity to others than those involved in their production, processing, treatment, transportation, and for utilization. The use of the most common and universal mixture of gases - air - is begun at birth by all living creatures and their discontinuation of its use terminates existence. Modern man rides on air in his tires, rides through it for high-speed transportation, and uses it for his comfort in the heating and air conditioning of his domicile.
