    Garrick's Improvements in Respiratory and Inhaling Apparatus. the air to he inspired, and which (like the preceding apparatus) is to he worn upon the body, hut under the outer clothes or garments, and is constructed as herein-after described. This apparatus consists of a case divided by a perforated or reticulated diaphragm into two compartments. 5 In one of these is inserted through an aperture in the diaphragm felt, wool, or other absorbent saturated or impregnated with any medicinal matter with which it is wished to impregnate the air to be inhaled. This compartment communicates with an air chamber (furnished with inlet and outlet valves) similar to that lierein-before described with reference to 10 the respirator constituting the first part of my Invention, which chamber also is provided with a flexible tube terminating in a mouth-piece. In the other compartment, which is closed by a door of perforated sheet metal or wire gauze, felt, or flannel, or other suitable filtering medium, is placed and secured so as to constitute the respirator, which may if desired be 15 kept moist by water contained in a receptacle formed at the lower part of the compartment occupied by the said filtering medium. At each inspiration of the user air enters the respirator through the perforations in the door thereof, and thence passes through the felt or flannel, or other filtering medium, through the perforations in tbe diaphragm, and 20 thence through the medicated medium placed in the inner compartment of the inhaler, where it is impregnated with the medicinal matter used, and from which it passes through the air chamber and tube, as in the respirator last described, the said air being warmed on its passage by the animal heat of the person using it. % * 25 In both the foregoing arrangements, instead of placing the inlet and outlet valves in a chamber formed on the inhaling apparatus, as herein¬ before described, they may be placed in the tube near the mouth-piece. My Invention further consists of an inhaling apparatus, which instead of being worn on the person may be stood on a table for the purpose of 30 warming, cooling, purifying, or medicating the air drawn through it by the user. This apparatus consists of a case made of wickerwork, per¬ forated vulcanite, or perforated sheet metal or wire gauze, over which is stretched felt or flannel, and to the upper part of which is connected the flexible tube herein-before described, in which and near the mouth-piece 35 thereof the inlet and outlet valves are placed. When it is wished to cool the air respired the lower part of this case is immersed in a pan or vase containing water, which being absorbed by
