THE BLOOD. 



If we calculate what quantity of P 2 O 5 would have been found had the 

 compound Ca 3 2(P0 4 ) existed in the serum we obtain the following results. 



A would have contained - 0146 P 2 O 5 

 B 0-0182 



C 0-0127 



G 0-0131 



The following tabular views represent the constitution of the saline 

 constituents of the liquor sanguinis and serum as derived from the most 

 reliable researches. It is to be remembered that in reference to the amount 

 of phosphoric acid the older analyses of Lehmann and Schmidt are un- 

 reliable, and that for this the results of Pribram and Gerlach are to be 

 taken.
