 the gastric juice on coagulated albumen, 106. 



DIFFUSION OF GASES. Explains the fact that nitrogen is given out 

 through the skin of animals, 113; and the poisonous action of 

 feather- white wine, 111. 



DIGESTION. Is effected without the aid of the vital force, by a meta- 

 morphosis derived from the transformation of a substance proceed- 

 ing from the lining membrane of the stomach, 105. The oxygen 

 introduced with the saliva assists in the process, 109. Lactic acid 

 has no share in it, 107. 



DISEASE. Theory of, 242 et seq. Cause of death in chronic disease, 

 25. Disease of liver caused by excess of carbon or deficiency of

DOG. Amount of bile secreted by, 62. Digests the gelatine of the 

 bones, 94. His excrements contain only bone earth, 95. Concre- 

 tion of urate of ammonia said to have been found by Lassaigne in a 

 dog, doubtful, 139 (note.) 



DUMAS. His analysis of choleic acid, 305 ; of choloidic acid, ib. ; of

 borrowed from Liebig, 41. 



E. 



EGGS. Albumen of the white and of the yolk identical, 103. Analy- 

 sis of both, 298; of lining membrane, 303. The fat of the yolk 

 may contribute to the formation of nervous matter, 103. This fat 

 contains iron, ib. 



ELALDEHYDE. See Aldehyde. 



ELEMENTS. Of nutrition. 92. Of respiration, ib.

 on ulcers, 116. 



EQUILIBRIUM. Between waste and supply of matter is the abstract 

 state of health, 233, 246. Transformations occur in compounds in 

 which the chemical forces are in unstable equilibrium, 104.

ETTLING and WILL. Their analysis of lithofellic acid, 312. 



EXCREMENTS. Contain little or no bile in man and in the herbivora, 

 none at all in the dog and other carnivora, 62. Those of the dog
