OFFICIAL INSPECTIONS J%. 3 



It is necessary that every insectic: \i containing arsenic carry 

 in addition to the weight, a chemical analysis stating the mini- 

 mum percentage of total arsenic and the maximum percentage 

 of water soluble arsenic which it contains. Standards are fixed 

 for Paris green following the Federal law so that Paris green is 

 adulterated if it does not contain at least 50 per cent of arseni- 

 ous oxide (As^O) or if it contains arsenic in water soluble 

 form that is equivalent to more than 3.5 per cent of arsenious 

 oxide (AszO) ; and in the case of lead arsenate it is adulterated 

 if it contains more than 50 per cent of water, if it contains total 

 arsenic equivalent to less than 12.5 per cent of arsenic oxide 

 (AssOs) and if it contains arsenic in water soluble form equiva- 

 lent to more than 75 per cent of arsenic oxide (AS2O). 



A fungicide or insecticide is adulterated if : — its strength or 

 purity falls below the professed standard under which it is 

 sold ; any substance has been substituted wholly or in part for 

 the article; any valuable constituent of the article has been 

 wholly or in part extracted; or if it contains any substance or 

 substances injurious to vegetation. 



A fungicide or an insecticide is misbranded if : — the package 

 or label bears any statement, design or device which is false or 

 misleading in any particular; the container does not carry the 

 statements named above ; the printed statement attached to the 

 container differs from the statements in the certificate ; the reg- 

 istration fee has not been paid ; it is in imitation of or offered 

 for sale under the name of another article ; it is labeled or 

 misbranded so as to deceive the purchaser; any of the contents 

 of the package as originally put up have been removed in 

 whole or in part and other contents placed in such packages; 

 or it consists partially or completely of any inert substance or 

 substances which do not prevent, destroy, repel or mitigate 

 insects or fungi and does not have the percentage amount of 

 such inert substances plainly stated on the label. 



Results of Analyses. 



The results of the examination of all of the samples received 

 from the Commissioner of Agriculture during the year 191 5 

 are given in the tables that follow. The reason for the small 

 number of samples is given in the Statement by the Executive 

 of the law on page 8.
