At the bottom of the reservoir, where the inhaler tubing is attached,is a piston val/e (G), placed there for absolute security against operations are suspended with the receiver full of gas. At theopposite side (not seen in cut) is a pipe to which the cylinder yoke isconnected by means of rubber tubing (L). Near the top of the reservoiris a wooden fork (H), to support the inhaler when not in use. The bell(F) works on the guide-rod (I).

Nitrous oxide narcosis is obtained so quickly that it is difficultto arrange its manifestations into groups. The initial sensa-tions are usually agreeable and exhilarating. There is subjectivedizziness, noises in the ears, tingling and loss of body are present and may result in mental exhilaration or de-pression, or in pugnaciousness. Generallv unconsciousness is 74 NITROUS OXIDE reached before the subject can speak. There is an irresistibledesire to inhale deeply, and the respirations are deeper andquicker than normal. The pulse is fuller and more rapid thanusual. As unconsciousness is reached disturbed psychical condi-tions may arise, especially if the subject be disturbed, roughlyhandled, or if the operation be begun
