Acid. 



— Acetic. Composition ; and relation to that of aldehyde, 279, 

 280. 



—Benzoic. Composition, and relation to that of oil of bitter 

 almonds, 279, 280. Converted into hippuric acid in the 

 human body, 150, 325. 



— Carbonic. Is the form in which the inspired oxygen and the 

 carbon of the food are given out, 13. Its formation in the 

 body the chief source of animal heat, 17 — 22. Occurs com- 

 bined with potash and soda, in the serum of the blood, 41. 

 Formed by the action of oxygen on the products of the 

 metamorphosis of the tissues, 60. Its formation may also 

 be connected with the production of fat from starch, 85 — 9 1 . 

 Generated by putrefaction of food in the stomach of animals, 

 115. Also by the fermentation of bad wine in man, when 

 it causes death by penetrating into the lungs, 116. Escapes 

 through both skin and lungs, ib. Produced, along with 

 urea, by the oxidation of uric acid, 140. Produced, with 

 several other compounds, by the oxidation of blood, ib. May 

 be formed, along with choleic acid, from hippuric acid, 

 starch, and oxygen, 152. Also, along with choleic acid, 

 urea, and ammonia, by the action of water and oxygen on 

 starch and proteine, ib. Produced, along with fat and urea, 

 from proteine, by the action of water and oxygen, in the 

 absence of soda, 154. Combines with the compound of
