Morton, of Boston, in the County of Suffolk and State of Massachusetts, have invented an inhalation apparatus to be used for the purpose of administering to persons or introducing into their lungs the vapors of ether or various other chemical matters ; and we do hereby declare that the same is fully described and represented in the following specification and accompanying drawings [shown in Fig. 153], letters, figures and references thereof.
