herbivora, 150. In man, 157-160. May be replaced by azotized 

 vegetable compounds, 161. Theory of this, 168-172. Of the 

 transformation of the bile, or of choleic acid ; how related to the 

 constituents of urine, 147.

BENZOIC ACID. See Acid, Benzoic. 



BERTHOLLET. His analysis of oxalic acid, 311. 



BERZELIUS. His analysis of potato starch, 286; of sugar of milk, 

 287 ; of gum, ib. ; of cane-sugar, 289. On excretion of carbon, 321. 



BEZOAR STONES. See Acid, Lithofellic. 



BLANCHET. His analysis of solanine, 313. 



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

 tissues, along with urate of ammonia, 130. May be represented by 

 choleate of soda, with which, however, it is not identical, 307. 

 Products of its transformation, 129, 306. Remarks on these, 305- 

 308. Origin of bile, 60, 137. Starch, &c., contribute to its for- 

 mation in the herbivora, 141, 148, 150, 152, 157. Soda essential to 

 it, 146, 153, 155. Relation of bile to urine, 148. To starch, 150. 

 To fibrine, 130. To caffeine, &c., asparagine, and theobromine, 

 271. For the acid substances derived from bile, choleic, choloidic, 

 and cholic acids, see Acid, choleic, &c. Yields taurine, 128. 

 Contains cholesterine, 82, 307. Also stearic and margaric acids, 

 ib. Its function : to support respiration and produce animal heat 

 by presenting carbon and hydrogen in a very soluble form to the 

 oxygen of the arterial blood, 59 - 63. Amount secreted by the dog, 

 the horse, and man, 62. It returns entirely into the circulation, 

 and disappears completely, 59-61. 



BLOOD. The fluid from which every part of the body is formed, 8. 

 Its chief constituents, 38. How formed from vegetable food, 44. 

 Can only be formed from compounds of proteine, 47. Is therefore 

 entirely derived from vegetable products in the herbivora. and indi- 

 rectly also by the carnivora, which feed on the flesh of the former, 

 48. Its composition identical with that of flesh, 127. Analysis of 

 both, 304. The secretions contain all the elements of the blood, 

 126. Its relation to bile and urine, 129. Products of the oxidation 

 of blood, 133. Excess of azotized food produces fulness of blood 

 and disease, 139. Soda is present in the blood, 153-155. Impor-
