The availability of the apparatus tomeet this requirement appears to me to be the chief advantage that it offersover the other inhalers. If care be not taken inthis method of use, liquid chloroform will be dis-charged from the apparatus instead of the vapor. Occasionally ether and cliloroform are employedinterchangeably in the same case, chloroform being.
