    Garrick's Improvements in Respiratory and Inhaling Apparatus. medium moist. E is a vessel for holding water. The upper edge of this vessel is turned inward and bent down, as shown at f9 in order to prevent the water contained in the said vessel from being spilled when the respirator is being used. The said vessel encloses the lower part of the respirator, and is held thereto by elastic bands fl, fl9 which 5 pass over ears f2, /2, and c8, <?8, formed on or affixed to the ends of the said vessel E and air chamber 0, respectively. By this means the filtering medium covering the lower part of the frame A is kept constantly immersed in water, which by capillary attraction rises to that part of the filtering medium not covered by the water vessel E, 10 through which parts the air to he inspired is drawn, which air is thereby moistened, cooled, and purified. My Invention further consists of a combined inhaling and respiratory apparatus which is more especially designed to warm and medicate #> the air respired. This apparatus is illustrated in [Figures 4, 5, 6, and 7 15 of the accompanying Drawings, [Figure 4 being a front view, [Figure 5 a plan, [Figure 6 (which is drawn of the full size) a vertical section taken on the line 3, 4, [Figure 4, and [Figure 7 a front view showing the case open. The said apparatus consists of a case G divided by a diaphragm g1 of 20 wire gauze or perforated sheet metal into two compartments g3, H. The said diaphragm is provided with a sliding shutter gz, which covers an aperture therein, through which aperture felt, wTool, or other absorbent I saturated or impregnated with any medicinal matter with which it may he wished to impregnate the air to be inhaled may be put 25 into the said inner compartment g2. This compartment communicates with an air chamber provided with inlet and outlet valves, and a flexible tube terminating in a mouth-piece, as in the arrangement herein last described. In the other compartment (H) felt or flannel, or other suitable filtering medium A1, is placed. The outer side of this compart- 30 ment consists of a hinged door h2 of sheet metal, part of which door is perforated, or is formed of wire gauze ¥. On the inside of the said door and near the edges thereof a tube A4 is affixed, in the upper part of which tube an aperture A5 is made, which aperture is provided with a screw stopper A6; and at the lower part of the said tube, on the side 35 next the filtering medium A1, small perforations A7, A7, are made. The method of using, and the action of this respirator are as follows:—The apparatus is suspended from the neck, and the mouth-
