 gas from the abdomen of cows after excess in fresh 

 food, 93. His researches on the brain, 21, 57. 



Frequency of the pulse and respiration in different 

 animals, 15, 87. 



Fruits. Contain very little carbon, and hence are 

 adapted for food in hot climates, 15. 

 G. 



Gas. Analysis of gas from abdomen of cows 

 after excess in fresh food, 39, 93. Analysis of 

 gas from the stomach and intestines of executed 

 criminals, 39, 93. 



Gastric Juice. Contains no solvent but a sub- 

 stance in a state of metamorphosis, by the pre- 

 sence of which the food is dissolved, 37. Con- 

 tains free acid, 37. Contains no lactic acid, 38. 

 In the dog has been found to contain iron, 38. 

 See Digestion, Chyme, Food. 



Gay-Lussac and Thenard. Their analysis of 

 starch, 88 ; of sugar of milk, and of gum, 89 ; of 

 cane sugar, 90 ; of wax, 92 ; of oxalic acid, 99. 



Gelatine. Is derived from proteine, but is no 

 longer a compound of proteine, and cannot 

 form blood, 42 et seq. May serve as food for 

 the gelatinous tissues, and thus spare the sto- 

 mach of convalescents, 35, 43. In starvation 

 the gelatinous tissues remain intact, 35. Its 

 relation to proteine, 42. Its formula, 46. Its 

 analysis, 94, 100. 



'.ToebeL His analysis of gum, 89. 



Globules of the blood are the carriers of oxygen 

 to all parts of the body, 54 55. They con- 

 tain iron, 77 et seq. 



Gluten. Contains vegetable fibrine, 22. Ana- 

 lysis of it, 87. 



Gmelin. On the sugar of bile, 47. 



Goose. How fattened to the utmost, 34,

Grape-sugar. An element of respiration, 35. Is 

 identical with starch sugar and diabetic sugar, 

 29. Its composition, 29. Its analysis, 88. 



Growth, or increase of mass, greater in gramini- 

 vora than in carnivora, 31. Depends on the 

 blood, 21 ; and on compounds' of proteine, 37, 

 See Nutrition.

 position, 35. Is related to sugar of milk, 35.

 of wax from honey of the bee, 91.

 42. Analysis of proteine from hair, 93. 



Hay. Analysis of, 89. 



Hepatic Diseases. Cause of, 16. 



Herbivora. Their blood derived from compounds 

 of proteine in their food, 23. But they require 

 also for their support non-azotized substances, 

 28. These last assist in the formation of their 

 bile, 47 et seq. They retain the phosphoric 

 acid of their food to form bone and nervous 

 matter, 31. Their urine contains very little 

 phosphoric acid, 31. The energy of vegetative 

 life in them is very great, 31. They become 

 fat when stall-fed, 31.

 ing the winter sleep, 17. They secrete bile

 butes to produce the animal heat, 17.

 getable caseine, 87; of gluten, 87; of the albu 

 men of yolk of egg, 93, 94; of the albumen of
