336 INDEX. 



Effects of superabundant azotized food, 138, 139. Non-azolized 

 food contributes to the formation of bile, and thus to respiration, 

 140 et seq. Salt must be added to the food of herbivora, in order 

 lo yield soda for the bile, 154. Caffeine, &c., serve as food for the 

 liver, 178. The vegetable alkalies may be viewed as food for the 

 organs which form the nervous matter, 179. Amount of food con- 

 sumed by soldiers in Germany, 275. Its analysis, 272 Food of 

 the horse and cow compared with their excretions, 279, 280. 



FORMULAE. Explanation of their use, 268. How reduced to 100 

 parts, 269. Formulae of albumen, fibrine, caseine, and animal tis- 

 sues, 120. Formula of proteine, 116 ; of blood and flesh, 127; of 

 fat, 82; of cholesterine, 82; of aldehyde, acetic acid, oil of bitter 

 almonds, and benzoic acid, 268; of cyamelide, cyanic acid, and 

 cyanuric acid, 268; of choleic acid, 128; of choloidic acid and 

 cholic acid, 128; of gelatine, 135; of hippuric acid, 143; of litho- 

 fellic acid, 146 ; of taurine, 148; of alloxan, 148. See Analysis. 



FRANCIS. His analysis of picrotoxine, 313. 



FREMY. Lameyran and Fremy. Their analysis of gas from the ab- 

 domen of cows after excess in fresh food, 299. His researches on 

 the brain, 43, 174. 



FREQUENCY of the pulse and respiration in different animals, 18, 281. 



FRUITS. Contain very little carbon, and hence are adapted for food 

 in hot climates, 16.

GAS. Analysis of gas from abdomen of cows after excess in fresh 

 food, 110, 299. Analysis of gas from the stomach and intestines of 

 executed criminals, 111, 299. 



GASTRIC JUICE. Contains no solvent but a substance in a state of 

 metamorphosis, by the presence of which the food is dissolved, 104. 

 Contains free acid, 105. Contains no lactic acid, 107. In the dog 

 has been found to contain iron, 108. See Digestion, Chyme, Food. 



GAY-LUSSAC and THENARD. Their analysis of starch, 286 ; of sugar 

 of milk, and of gum, 287; of cane-sugar, 289; of wax, 296; of 

 oxalic acid, 311. 



GELATINE. Is derived from proteine, but is no longer a compound 

 of proteine, and cannot form blood, 122 ct seq. May serve as food 

 for the gelatinous tissues, and thus spare the stomach of convales- 

 cents, 95, 124. In starvation the gelatinous tissues remain intact, 

 93. Its relation to proteine, 125. Its formula, 135. Its analysis, 301, 

 302. 



GOEBEL. His analysis of gum, 287.
