EESULTS OF ANALYSES. 



TABLE V. Arsenic content of wall papers Continued. 



35 



Nos. 436-468, inclusive, Nos. 59V641, inclusive, and No. 858 are samples from Massachusetts, the 

 only State which has enacted a law restricting the use of arsenic in papers and fabrics. 



Of the 537 samples of wall paper examined four of them, or 0.75 per 

 cent, contain more than 0.1 grain per square yard (7.8 mg per square 

 meter), the maximum amount allowed by the laws of Massachusetts. 

 It will be noted that two of these four samples are colored at least 

 partially with a red dye, two are partially colored with a green dye, 

 while one is colored neither red nor green, but has brown as the pre- 

 dominating color. It is also a fact worthy of notice that two of the 

 four samples came from England, one of the foreign countries which 

 has no laws limiting the amount of arsenic in papers and fabrics. 



Five of the samples, or 0.93 per cent, contain between 0.077 and 0.1 

 grain per square yard (0 and 7.8 mg per square meter). Here again 

 it will be noted that red is one of the predominating colors in four of 

 the samples and further that four of the samples are of foreign make,
