RESULTS OF ANALYSES. 43 



Table XII contains the results of the examination of furs to be used 

 as articles of dress in the form of neck pieces, muffs, coats, or robes. 



Of the 42 samples examined, 11, or 2G.2 per cent, contain from 20 to 

 1,700 times as much arsenic as would be allowed by the laws of Mas- 

 sachusetts; 4, or 9.5 per' cent, contain only a trace, while 27, or 64.3 

 per cent, contain no arsenic. This excessive amount of arsenic is 

 doubtless added during the process of preparing the fur, either to 

 preserve it or to repel injurious insects. Here again, as in the case 

 of stockings, are articles which, worn around the neck and hands, are 

 apt to come in extremely close contact with the skin. The presence 

 of arsenic in such articles as these is as injurious if not more so than 

 in hose, since it is usually present in much larger quantities; further- 

 more it is an intentional rather than an accidental constituent.

In Table XIII are given the results of the examination of three fur 

 rugs, which may be considered in connection with eight samples.
