faction, or other forms of metamorphosis, 170. Their action 

 on wounds and ulcers, 121. 



ARTERIES. Composition of their tunica media, 312. How de- 

 rived from proteine, 126. 



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

 60, 269. Contains a compound of iron, most probably per- 

 oxide, 269. Yields oxygen in passing through the capillaries, 

 60, 271. Contains carbonic acid dissolved or combined with 

 soda, 272. 



ASPARAGINE. Its composition, 325. Its relation to taurine and 

 bile, 180. Theory of its action on the bile, 181. 



ASSIMILATION. In animals it is independent of external influ- 

 ences, 3. Depends on the presence in the blood of compounds 

 of proteine, such as fibrine, albumen, or caseine, 40, 106. Is 

 more energetic in the young than in the adult animal, 67. Is 

 also more energetic in the herbivora than in the carnivora, 81. 



ATMOSPHERE. See AIR. 



AZOTISED PRODUCTS. Of vegetable life, 45, 176 182. Of the 

 metamorphosis of tissues. Necessary for the formation of bile 

 in the herbivora, 158. In man, 166, 168. May be replaced 

 by azotised vegetable compounds, 1 69 1 70. Theory of this, 

 177 182. Of the transformation of the bile, or of choleic 

 acid ; how related to the constituents of urine, 155.

BLANCHET. His analysis of solanine, 323. 



BILE. In the carnivora is a product of the metamorphosis of the 

 tissues, along with urate of ammonia, 136. May be repre- 

 sented by choleate of soda, with which, however, it is not iden- 

 tical, 317. Products of its transformation, 135, 317. Re- 

 marks on these, 315 318. Origin of bile, 61, 144. Starch, 

 &c., contribute to its formation in the herbivora, 146
