The amount of phosphoric acid is too small to form c-phos- 

 phates with the earths and alkalies, much less can the peroxide 

 of iron be considered as combined with phosphoric acid. 



The relative amounts per cent, obtained by the three ope- 

 rations are — 



Extracted by water ....... 60-90 



Extracted by muriatic acid .... 6-04

The whole analysis of the blood gave —

 Hence the statement formerly made, that the inorganic 

 constituents of the blood agree with those of many seeds, 

 is only partly correct. The inorganic constituents of the 

 wheat, excluding a considerable amount of chloride of so- 

 dium, consist almost entirely of pyrophosphates. The inor- 

 ganic constituents of peas and rape, which differ in regard 

 to the amount of alkaline chlorides they contain, nevertheless 

 agree generally in the amount of the oxygen of all the bases 

 being about half as great as that of the acids; whilst in the 

 inorganic constituents of the blood the bases are combined with 

 much smaller quantities of acids, so that the oxygen of the
