![inhaler [see Fig. 140] (using it in 125 cases, so far [1898]). This is a modification of Clover's inhaler [Clover'schen Maske1]. It consists of a metal dome, furnished with a rubber rim, which makes it possible to fit the dome tightly to the face, covering nose and mouth. It has an inspiratory and an expiratory valve. Over the former is attached a hollow ball, made in two pieces Fig. 141.—CHLOROFORM INHALER designed by Elser, of Strasbourg, c. 1848, which appears to have influenced the design of Breuer's inhaler (Fig. 140). A. Expiratory valve. B. Inspiratory valve at the screw-junction between the facepiece and the body of the inhaler. C. Hollow sphere, in two pieces screwing one into the other ; the lower piece pierced with holes to allow air to enter the inhaler. D. Stoppered filling aperture, for chloroform. Within the sphere, just behind the rosette of holes, was placed a strip of sponge, previously wrung out of hot water. On to this the chloroform was dropped through D. which fit accurately one into the other. This can be opened and a piece of lint inserted to receive the drug. A slot in the ball enables the drug to be sprayed in without lifting the inhaler. Breuer originally devised this inhaler for pental anaesthesia in Professor von Hacker's Surgical Department at the Sophien Hospital in Vienna. 1 Clover's portable regulating ether inhaler (see Fig. 92) was so referred to in German-speaking countries, and in France as masque de Clover (cf. p. 543), It is difficult to imagine why Lotheissen should have stated that Breuer's inhaler was a modification of Clover's.](https://iiif.wellcomecollection.org/image/b20457200_0528.jp2/full/800%2C/0/default.jpg)
