PHOSPHORUS FROM CASEINOGEN. 461 



10. The organic phosphorus produced by the action of trypsin 

 on caseinogen is not completely converted into inorganic phosphoric 

 acid by the action of 1 per cent, of caustic soda. The total quantity 

 of inorganic phosphoric acid produced by trypsin and subsequently by 

 1 per cent, caustic soda is 50 per cent, of the total phosphorus of 

 caseinogen. 



The expenses of this research were defrayed by a grant from the Government Grant 

 Committee of the Royal Society.
