PARIS GREEN. 



The prescribed standard for the composition of Paris green is not less 

 than 50% arsenious oxide nor more than 3.50% water-soluble arsenious 

 oxide. 



Fifteen samples have been analyzed all of which were collected since 

 January 1st, 1915. In ever}' case the amount of arsenious oxide found 

 was well above the amount guaranteed, though, in five samples, (4871, 

 4873, 4875, 4877 and 4881) the amount of water-soluble ar.senious oxide 

 was more than the amount prescribed by law.
