A function proper to animals, the object of which is, to place the materials of the blood-the mixture of the venous blood with lymph and clyle, - in contact with atmospheric air, in order that it may acquire the vivifying qualities which belong to arterial blood. The organs for executing this function are, in the mammalia, birds, and reptiles, the lungs. In man. the respiration consists of mechanical and chymieal phenomena. The mechanical are Inspiration and Expiration. The evident chymieal phenomena consist in the formation of a certain quantity of carbonic acid, the absorption of a part of the oxygen of the air, and the disengagement of a quantity of water in the state of vapour. In the healthy condition the respiration is easy, gentle, regular, and without noise. In man, the respirations are generally about 35 per minute in the first year of life; 25 during the second; 20 at puberty; and 18 in the adult age. The air of respiration has been divided into first, the residual air, or that which cannot be expelled from the lungs, but remains after a full and forcible expiration, estimated at 120 cubic inches: secondly, the supplementary or reserve air or that which can be expelled by a forcible expiration, after an ordinary outbreathing, valued at 130 cubic inches: thirdly, the breath, tidal or breathing air, valued at 26 cubic inches: and fourthly, the complementary or complemental air, or that which can be inhaled after an ordinary inspiration, which amounts to 100 cubic inches. This estimate gives 250 cubic inches as the average volume of air which the chest contains after an ordinary expiration.
