OFFlCIAIv INSPECTIONS 4/. 1/ 



Grasselli's Arsenate of Lead Paste. A one pound package and 

 a five pound package were examined. The one pound package 

 was full weight, carrying 16.5 ounces. The pastes themselves 

 analyzed very much alike. They carried about ten per cent of 

 arsenic and nearly three times the permitted amount of soluble 

 arsenic, containing 1.28 per cent arsenic soluble in water. 



The Orchard Brand Arsenate of Lead, made by the Thomsen 

 Chemical Co., Baltimore, Md., was full weight, a five pound 

 package carrying 89 ounces of lead arsenate. It carried about 

 ten per cent of total arsenic and 1.18, or two and a half times 

 too much water soluble arsenic. 



The P. W. R. Lead Arsenate Paste, made by the Powers- 

 Weightman-Rosengarten Co., Philadelphia, was short weight, 

 the one pound package containing 15.4 ounces. It carried about 

 10 per cent of total arsenic and .92 per cent of arsenic soluble in 

 water, or practically double the amount permitted under the law. 



New process Neutral Arsenate of Lead, made by the Sherwin- 

 VVilliam's Company was short weight, the one pound package 

 having 14.2 ounces of lead arsenate. It just barely passed the 

 requirements for the total arsenic, carrying about 8.25 per cent 

 total arsenic. The water soluble arsenic was .51 per cent and 

 practically the same as that permitted under the law. 



Swift's Arsenate of Lead, made by the Merrimac Chemical 

 Co., Boston, was full weight, the one pound package containing 

 1 7. 1 ounces of arsenate of lead. It contained about 10 per cent 

 of total arsenic and .63 per cent water soluble arsenic. 



The United States Department of Agriculture maintained 

 successful cases against the Sherwin-Williams Company because 

 of their lead arsenate containing less than the claimed total 

 arsenic, and more than the minimum of the water soluble 

 arsenic. Judgment was also found against the F. W. Devoe & 

 C. T. Reynolds Company of Chicago, 111., for lead arsenate 

 which was deficient in total arsenic and high in water soluble 

 arsenic. 



Miscellaneous Arsenic Materl\es. 



Watson's Soluble Arsenoid distributed by John Watson
