The results of these analyses show conclusively that in 

 some cases men engaged in spraying acquire dangerous 

 amounts of arsenic. That actual sickness resulting from this 

 work is rare, is shown by the fact that but few of our many 

 employees lose time from this cause. A case of this kind 

 investigated by the writer in 1896 proved to be one of un- 

 mistakable arsenical poisoning, which in this instance was 

 not strange, since less than one week previous to the time 

 the man was taken sick he was ol)served to he especially 

 careless in the use of the poison, allowing the drippings of 

 the spraying pole to run freely up his arms and probably over 

 the greater part of his body. Nowhere, perhaps, do we find 

 a better illustration of the contempt bred by familiarity than 

 in the manner in which men engaged in spraying make use 

 of insecticides. In the case of our employees an excuse is 

 found in the high state of physical vigor that characterizes 

 the whole force, — the natural result of an active, outdoor 

 life. 



Strangely enough, the most frequent cause for complaint
