ARSENATE OF LEAD. 



Three samples of arsenate of lead paste and nineteen of the powder 

 form were analyzed. One sample of paste (501) contained in the orig- 

 inal package was found to contain more than 50 per cent of moisture 

 and less thaji the legal requirement of arsenic oxide (AS2O5). Five 

 samples of dry arsenate of lead manufactured by H. J. Smith & Co., 

 Utica, New York, were analyzed. Three of these (Nos. 589, 590 and 591) 

 were found to be mixtures of lead arsenate and calcium arsenate with 

 a preponderance of the calcium arsenate and an excess of calcium car- 

 bonate. These cases were referred to the Federal Insecticide Board and 

 a Federal inspector was sent to the State to take charge of the matter. 

 Settlement was made by the company covering these cases. 



Two samples (Nos. 489 and 508) manufactured by the Toledo Rex 

 Spray Co., Toledo, Ohio, were found to be slightly below guarantee for 

 total arsenic oxide.
