Report No. 187
Gas Chamber: The convict is undressed except his short and tied to a chair in an air tight gas chamber. Stethoscope is attached to his chest and tubes taken out of gas-chamber to determine the convict is dead. Hydro-Choric acid is pumped 92through valve into a pan followed by potassium cyanide or sodium cyanide which is dropped mechanically in the pan producing lethal gas. The death occurs in six to eight minutes and there is no mutilation of body but there are wild convulsions. The chamber is then neutralized with chemicals. This method is expensive and complicated. Nevada is the first State to use gas chamber in 1924. Five States in USA use this method.
