A rubber bag is attached to this chim-neypiece. At the other end of the bag a rubber tube with a stop-cock connects the bag to the gas cylinder. If the Gatch methodof administration of gas and oxygen is to be used, a Y-piece con-nects tbe nitrous oxid and oxygen cylinders to the bag. The appara-tus is reduced in weightand bulk to nearly one-half that of the Bennettapparatus, having onecylinder and one bag. Theobject of the nitrous oxid-ether sequence is to avoidthe first and second stagesof ether narcosis with itspreliminary excitement,struggling, coughing, hold-ing the breath, swallowing,and all other disagreeableand disgusting effects thatwere formerly connectedwith this stage of etheriza-tion, and to enter imme-diately into the third stage for surgical anesthesia. The patient isthus enabled to take advantage of one of the safest general anesthetics
