If the faucet is locatedat the top of the building some difficulty may be experi-enced in securing sufficient water power to produce thedesired result. The essential features of the apparatusare shown in Fig. 131. Aspiration by electricity is often used where ethervapor is being delivered for throat work. In this case thesuction produced by the blower which provides air to formthe ether vapor is employed. The disadvantage of thisparticular arrangement lies in the fact that the air usedto vaporize the ether is taken (by suction) from the de- 21 321 322 ANAESTHESIA.
