Acid. 



— Parahanic. Analysis of, 321. 



— Phosphoric. Exists in the urine of the camivora in consider- 

 able quantity, 78, 163. Its proportion very small in that 

 of the graminivora, 79. Derived from the phosphorus of the 

 tissues, 78. It is retained in the body to form bones and 

 nervous matter, 80. 

 — Sulphuric. Exists in the urine of the camivora, 78, 163. De- 

 rived from the sulphur of the tissues, 78. 

 — Uric. Its composition, 318. Products of its oxidation, al- 

 loxan, oxalic acid, carbonic acid, urea, &c., 137, 140. Is 

 probably derived, along with choleic acid, by the action of 

 oxygen and water on blood or muscle, 136. Disappears 

 almost entirely in the system of man and of the higher ani- 

 mals, 5^, 137. Appears as calculus, when there is a defi- 

 ciency of oxygen, 137. Never occurs in pthisical cases, ih. 

 Yields mulberry calculus when the quantity of oxygen is 

 somewhat increased, but onlv urea and carbonic acid with a 

 full sui:)ply of oxygen, ib. Uric acid calculus promoted by 

 the use of fat and of certain wines, 139. Unkno\vn on the 

 Rliine, ib. Uric acid and urea, how related to allantoine, 

 141 ; to gelatine, 142. Forms the greater part of the 

 urine of serpents, 54. Yields, with the elements of proteine 

 and oxygen, hippuric acid and urea, 151. How related to 

 taurine, 155, 156. Calculi of it never occur in wild car- 

 nivora, but often in men who use little animal food, 146. 

 Affinity, Chemical. Is the ultimate cause of the vital pheno- 

 mena, 9, 10. Is active only in the case of contact, and de- 

 pends much on the order in which the particles are arranged, 

 205. Its equilibrium renders a compound liable to transfor- 

 mations, 207. In producing the vital phenomena, it is modi- 

 fied by other forces, 209. It is not alone the vital force or 

 vitality, but is exerted in subordination to that force, 232. 

 Air. Introduced into the stomach during digestion with the 

 saliva, 113. Effects of its temperature and density, drj-ness, 

 &c., in respiration, 15, 16. 

 Albumen. Animal and vegetable albumen identical, 47, 48. 

 Their composition, 293, 294, 308, 309. Vegetable albumen, 

 how obtained, 45. Is a compound of proteine, and in organic 

 composition identical with fibrine and caseine, 47, 104, 106.
