FUMIGATION WITH CARBON BISULPHID 26 1 



more marked and a severe headache, at least, might 

 ensue. If upon the approach of dizziness, the operator 

 goes at once to a window, or better still out of doors, 

 an abundance of fresh air will in a few minutes remove 

 all ill effects, and no injury will result from the experi- 

 ence. The inhalation of the fumes can be somewhat 

 retarded by tying a wet handkerchief tightly over the 

 face. This, however, merely diminishes the amount of 

 air taken into the lungs without affecting the propor- 

 tion of vapor contained therein. ' ' 



When obliged to enter a room in which the air is 

 charged with any considerable amount of vapor, Mr. 

 Hinds makes use of the following simple device, which 

 is perfectly effectual : A large paper bag holding 20 

 quarts or more is tied tightly around a short piece of 

 tubing of glass, rubber, or metal. When inflated, 

 the bag contains sufficient air to enable one to respire 

 into it for several minutes without discomfort. Being 

 very light, it can be carried by the tube in the mouth, 

 thus leaving the hands free for any work desired. 

 Carbon bisulphid can be handled with much greater 

 safety and far less fear than is possible where the user 

 knows there is danger but does not know just what the 

 danger is. The danger from its use is practically of 

 the same kind as that from gasoline, which is in com- 

 mon daily use. The danger is very much less, how- 

 ever, since every precaution is taken to keep carbon 

 bisulphid from the proximity of fire, while gasoline is 

 used principally in connection with it. 



Commercial uses. Although the insecticide proper- 

 ties of carbon bisulphid were discovered by Doyere in 

 1856, and tested three years later by Baron Paul The-
