ANIMAL HEAT. Derived from the combination of oxygen with the 

 carbon and hydrogen of the metamorphosed tissues, which proceed 

 ultimately from the food, 16, 17. Is highest in those animals whose 

 respiration is most active, 18. Is the same in man in all climates, 

 18, 19. Is kept up by the food in proportion to amount of external 

 cooling, 21. Is not produced either by any direct influence of the 

 nerves, or by muscular contractions, 28-32. Its amount in man, 

 32. Chemical action the sole source of it, 36. The formation of 

 fat from starch or sugar must produce heat, 88 -90. The elements 

 of the bile, by combining with oxygen, serve chiefly to produce 

 it, 59. 



ANIMAL LIFE. Distinguished from vegetable life by the absorption 

 of oxygen, and the production of carbonic acid, 2. Must not be 

 confounded with consciousness, 6, 7. Conditions necessary to an- 

 imal life, 9,11. Depends on an equilibrium between waste and 

 supply, 233 - 242. 



ANTISEPTICS. They act by putting a stop to fermentation, putrefac- 

 tion, or other forms of metamorphosis, 162. Their action on 

 wounds and ulcers, 116. 



ARTERIES. Composition of their tunica media, 312. How derived 

 from proteine, 121. 



ARTERIAL BLOOD. Conveys oxygen to every part of the body, 59, 

 257. Contains a compound of iron, most probably peroxide, 257. 

 Yields oxygen in passing through the capillaries, 59, '259. Contains 

 carbonic acid dissolved or combined with soda, 260. 



ASPARAGINE. Its composition, 315. Its relation to taurine and bile, 

 170. Theory of its action on the bile, 171. 



ASSIMILATION. In animals it is independent of external influences, 

 3. Depends on the presence in the blood of compounds of pro- 

 teine, such as fibrine, albumen, or caseine, 38-103. Is more en- 

 ergetic in the young than in the aduH animal, 65. Is also more 

 energetic in the herbivora than in the carnivora, 78. 



ATMOSPHERE. See AIR. 



AZOTIZED PRODUCTS. Of vegetable life, 44, 167, 173. Of the meta- 

 morphosis of tissues. Necessary for the formation of bile in the 

 28*
