The gas bag is filled and the face piece is patient is made to rebreatbe N20. When the respira-tions become deep and more rapid than normal, the etheris cautiously turned on. If there is no respiratory spasm,it is gradually increased. When full ether is reached, thegas bag is replaced by the rebreathing bag. A smallamount of ether is poured into the ether chamber, througheach of the three holes. Relaxation comes on quickly and. Fia. 73.— Bennett apparatus, with pas attachmentand bag for inductioo. Fig. 74.— Bennett apparatus with etherrebreathing bag for maintenance. the stage of maintenance is soon reached. When properlymanaged, the stage of induction is all that can be desired. During the stage of maintenance, however, we arelikely to feel that improper provision has been made for: (a) The changing of the gauze, which has becomewater soaked by the condensed respiratory moisture; (b)the giving of small, constant doses of ether; (c) unob-structed rebreathing. Furthermore, we cannot see the patients mouth 138 ANESTHESIA through the opaque, metal mask and, after an hour ormore, the weight of the apparatus becomes troublesome. Unless one is very expert, the patient will not be underproper control. The wet gauze will not hold the etherpoured upon it, allowing the latter to run down into theface piece. With care and good judgment these disad-vantages are not so marked. They will be fo
