1 Two analyses. 



' The sample contained 51.20 per cent of potassium oxide, showing it to be muriate of potash. It was 

 apparently tagged sulfate of ammonia by mistake. It showed a commercial shortage of $17.02 per ton. 



3 The sample contained .72 per cent of potassium oxide and ,63 per cent of nitrogen in form of nitrates. 

 It is probable that a sack of muriate of potash and nitrate of soda were labeled by mistake with sulfate of 

 ammonia tags. The material had a commercial valuation of $59.82 per ton; it showed a commercial 

 shortage of $1.86 per ton, and called for a rebate of $2.11 per ton. 



Synthetic Urea and Organic Ammoniate. 



I The material contained 2.42 per cent phosphoric acid, of which 2.01 per cent was in available form; 

 potassium oxide .36 per cent. There was 5, 16 per cent of water insoluble nitrogen which showed an acti\aty 

 of 45 per cent by the alkaline and 87.20 per cent by the neutral permanganate method. Two analyses 

 were made.
