SOLUBLE SULFUR COMPOUND. 



Three samples of soluble sulfur compound were analyzed. Attention 

 is called to the fact that the active ingredient in this compound is sodium 

 polj'sulfide and that the amounts found were below guarantee in every 

 case. This material deteriorates rapidly on exposure to the air and the 

 containers should be tightly closed at all times. 



ARSENATE OF LEAD. 



The insecticide law fixes the standard for arsenate of lead, making it 

 compulsory for all lots offered for sale to contain not less than 12.50% 

 arsenate oxide and not more than 0.75% arsenate oxide in forms soluble 

 in water nor more than 50% water. 



Twenty samples of arsenate of lead were collected, twelve of which 

 were in the form of dry powder and eight in the form of paste. Four 

 samples of dry arsenate of lead contained slightly more than the legal 

 limit for water soluble arsenic oxide but the excess was less than 0.10% 

 in every case which may be disregarded. In every case the net weight 

 of the packages was found to be in excess of that claimed. In one case, 

 No. 270, the amount of water found was 0.91% more than the legal 

 standard.
