 ninety-eight per cent strength, preferably in lumps about the size of a walnut : 

 one and one-half ounces commercial sulphuric acid, best grade, and two and one- 

 fourth fluid ounces of water. First : Place the water in a three-gallon vessel 

 (which may be glazed earthenware) : to this add the acid and finally the 

 potassium cyanide. (The cyanide would be better enclosed in a small paper bag 

 in which a hole is torn. ) Immediately close the doors or openings, taking all pre- 

 cautions against inhaling the gas, as it is one of the most violent ix)isons known. 

 After leaving box or tent closed for forty minutes open all doors and allow at
