    Inhaling Apparatus. (This Invention received Provisional Protection only.) PROVISIONAL SPECIFICATION left by William Clark at the Office of the Commissioners of Patents, with his Petition, on the 9th February 1864.—A communication from abroad by Charles Pierre Baillemont, Gentleman, of 29, Boulevart St. Martin, Paris. 15 I, William Clark, of 53, Chancery Lane, in the County of Middlesex, Engineer and Patent Agent, do hereby declare the nature of the said Inven¬ tion for “ Improvements in Apparatus for Inhaling Air when charged with Vapours,’* to be as follows :— This Invention relates to an apparatus for introducing air charged with liquid particles into the mouth or nose, said air previously passing through a suitable liquid. This apparatus is made entirely of tin or other metal, and may be heated either direct or receive the liquid already heated when the medicinal air to be inhaled is required to be heated. Hitherto glass vessels have been used for ^ this purpose, furnished with tubes also of glass, one of which dips into the liquid while the other opens into the air above the liquid, and serves also for its aspiration. But this apparatus cannot be placed on a fire, and if a heated liquid be introduced the bottle invariably breaks ; this fragility of the recipient may also render its contents dangerous, while the tubes can only be ^ closed by corks, and inhalation by such means becomes difficult. In order to remedy these disadvantages I substitute metal for the glass recipient which has the further advantage of being hermetically closed at the junction of the tubes.
