A non-asphyxial anaesthesia can also beobtained by the addition of air to nitrous oxid can be maintained for hours at a time bythe addition of either oxygen or air, without the leastasphyxia, proving conclusively that nitrous oxid pos-sesses anaesthetic properties of its own. The initial sensations under nitrous oxid are of anagreeable and stimulating character, almost identicalwith those of ether and chloroform; and, when non-asphyxial and deep nitrous oxid anaesthesia is estab-lished, this anaesthesia is similar, in its main features,to that produced by other anaesthetics. Were nitrousoxid anaesthesia the result of simple oxygen depriva-tion, we should not expect the initial sensations pro-duced by the inhalation to be of an exhilarating char-acter. Nitrous oxid has, in fact, quite as great a claim.
