Artificial anaesthesia and anaesthetics . erture for the re-ception of a graduated syi-inge, by which the chloroform is supplied Op-posite that part of the box to whicli the nozzle of the bellows is attached 19 ETHEK-INHALEIIS. 39 an opeu tube, to which the bag can be adapted. The api^aratus being thusconnected, air is blown over the chloroform into the bag by means of thebellows. For each thousand cubic inches of air which the bellows tlu-owsin, forty minims of chloroform are supplied by means of the , since forty minims of chloroform produce about forty-five cubicinches of vapor, the atmosphere in the bag contains 4^ i^er cent, of chloro-iovia vapor. Of course, the percentage is determined at wlU by theamount of chloroform supplied. WTieu sufficient of the atmosphere has been thus prepared, the bag isdetached from the metaUic box and the mouth-piece applied. It is thensuspended in a convenient position from the collar of the administratorscoat. The position of administrator and patient is seen in the Mr. Clovers Apparatus. The advantage of this method of administration consists in the uniformstrength of the vapor in the bag. But it has to be further diluted bymanipulation of the valve in the mouth-piece as inhalation jjroceeds, con-sequently the advantage secured by the resei-voir is quite neutralized bythe mouth-piece, and the apparent superiority of the method is quitenegative in practice. ETHER-INHALERS. The iM-actical immunity from danger which attends the inhalation ofthe vapor of sulphimc ether, renders it almost unnecessary to employ anyspecial precautions against too great concentration of the vapor.
