Dry Powdered Arsenate of Lead. 



Only one sample was found. This was made by Corono 

 Chemical Company and was found to weigh net 1.02 pounds and 

 contained 0.3 per cent water, 21.10 per cent total arsenic and 

 3.36 water soluble arsenic. Xo standard has been adopted for 

 dry powdered arsenate of lead, but on the paste basis this was 

 above the standard so far as total arsenic is concerned and car- 

 ried an excessive amount of water soluble arsenic. 



Paris Green. 



According to the law a paris green is adulterated if : it does 

 not contain arsenic equivalent to at least 50 per cent of arseni- 

 ous oxide ; and if it contains water soluble arsenic equivalent to 

 more than 3.5 per cent of arsenious oxide. iVrsenious oxide 

 contains 75.8 per cent of metallic arsenic. 



In 1912 a sample of F. AA'. Devoe and C. T. Raynolds Com- 

 pany's brand of Paris green examined was full weight but car- 

 ried water soluble arsenic equivalent to 4.27 per cent of arseni-

 company was fined for selling Paris green adulterated because it 

 contained an excessive amount of water soluble arsenic."

 lead "]\Iade by Devoe and Raynolds Co., Chicago, New York 

 and Kansas City." In a letter to their attorneys F. W. Devoe
