 CHAPTER VIII.

 OF THE FUNCTION OF RESPIRATION.

 Respiration in the plant; in the animal—Aquatic and aërial
 respiration—Apparatus of each traced through the lower to the
 higher classes of animals—Apparatus in man—Trachea, Bronchi, Air
 Vesicles—Pulmonary artery—Lungs—Respiratory motions: inspiration;
 expiration—How in the former air and blood flow to the lungs; how
 in the latter air and blood flow from the lungs—Relation between
 respiration and circulation—Quantity of air and blood employed in each
 respiratory action—Calculations founded on these estimates—Changes
 produced by animal respiration on the air: changes produced by
 vegetable respiration on the air—Changes produced by respiration on
 the blood—Respiratory function of the liver—Uses of respiration  Page 1


 CHAPTER IX.

 OF THE FUNCTION OF GENERATING HEAT.

 Of the temperature of living bodies—Temperature of plants—Power
 of plants to resist cold and endure heat—Power of generating
 heat—Temperature of animals—Warm-blooded and cold-blooded
 animals—Temperature of the higher animals—Temperature of the different
 parts of the animal body—Temperature of the human body—Power of
 maintaining that temperature at a fixed point, whether in intense
 cold or intense heat—Experiments which prove that this power is a
 vital power— Evidence that the power of generating heat is connected
 with the function of respiration—Analogy between respiration and
 combustion—Phenomena connected with the functions of the animal body,
 which prove that its power of generating heat is proportionate to
 the extent of its respiration—Theory of the production of animal
 heat—Influence of the nervous system in maintaining and regulating the
 process—Means by which cold is generated, and the temperature of the
 body kept at its own natural standard during exposure to an elevated
 temperature                                                    Page 120
