Oxygen and Respiration,—Oxygen is necessary to respiral^ion,and is constantly taken into thelungs, from the atmosphere, in theprocess of breathing. No animal can live in an atmos-phere which does not contain a certain portion of uncom-hined oxygen. Oxygen, by the chemical action involved in the process of respiration, passesfrom a free state into a state of combination with other substances, and therebybecomes unfitted for the further support of animal life. If a bird be con-fined in a limited portion of atmospheric air, it will at first feel no inconve-nience ; but as a por
