Hence the phosphoric acid of the bases is to that of the 

 acids nearly as 3 : 5. The teleoxidic portion of the milk con- 

 tains c-phosphates, and the anoxidic portion yields by oxida- 

 tion c-phosphates also. 



Thus milk is a meroxidic substance. We might almost call 

 it a hemioxidic substance, if the large quantity of the alkaline 

 chlorides contained in the aqueous extract were excluded from 

 the teleoxidic portion, to which they evidently do not belong. 



The large amount of phosphoric acid in the teleoxidic por- 

 tion, and the considerable quantity which the anoxidic portion 

 yields on oxidation, are remarkable. It is hence evident, as 

 has frequently been remarked, how well the milk is adapted 

 for effecting the ossification of the bones in the mammalia. 



Whilst in the blood the bases predominate over the acids, 

 in the flesh we find little else than pyrophosphates, and in the 

 milk the bases for the most part form c-phosphates.

Examihatioti of the Inorganic Constituents of the M^ite and 

 Yolk of Hen's Eggs. By M. Poleck. 



These experiments were among the first made by the method 

 of carbonization, and were instituted before the process was 

 perfected ; they do not therefore deserve too much confidence, 

 although performed with great care. But as they appeared 

 to me of some importance, I shall briefly describe them. 



The principal source of error consists in the fact, that in 

 some of the analyses the alkali contained in the muriatic ex- 

 tract, not having been suspected to exist there, was over- 

 looked ; moreover, the exhausted carbonized mass being
