In using these more simple inhalers, the tongue canbe placed against the end of the tube in the moutdi dur-ing expiration, so that the expired air passes out throughthe nostrils, or otherwise the mouth must be removedfrom the instrument at each expiration, in order thatthe expired air shall not pass into the inhaler. Of lateyears, mouth-pieces to inhalers have been provided withvalves, which permit the medicated air to pass into themouth in inspiration, and direct the expired into theatmosphere, so that none of it contaminates the air en-tering the reservoir or apparatus. One of the best ofthese contrivances has been devised by Dr. Beigel, ofLondon,* the accompanying sketch of which in section(Fig. 4), sufficiently explains its construction: Thetwo valves (A and B) are made of vulcanite, and, acting Fig. Beigtls Mouth-Piece (from Beigel). extremely easily, close and open with great is obvious that the inhalation with each inspiration—during which the valve B gets closed—-takes place in * On Inhalation as a Means of Local Treatment of the Organsof Respiration by Atomized Fluids and Gases.

The apparatus of Sir Charles Scudaraore is substan-tially on the same principle as that of Mudge. It is aglass vessel with a double neck; though a wide-mouthedbottle, with two perforations through the closely-fittingcork, will answer the same purpose. Sir Charles directsthat the water in the inhaler should be abou
