weighed. Since the ash in different samples varies, the ash insoluble 

 in hydrochloric acid was calculated back to the original sample. 



Phosphorus in the ash. — The filtrate from the last determination 

 was made up to volume in a graduated flask, and phosphoric acid 

 determined in an aliquot according to the official volumetric method 

 (Jour. A. O. A. C, Vol. 1, No. 4, Pt. II, p. 3), allowing the solution 

 to stand 30 minutes or longer at about 45°. The phosphorus, reported 

 as P2O5, is calculated on the original sample. In many cases the P2O5 

 was determined gravimetrically (Jour. A. O. A. C, Vol. 1, No. 4, Pt. 

 II, pp. 1-3).
