    COMPOUND INHALERS FOB “ANAESTHESIA BY MIXED VAPOURS.” The principles of the new system of Anaesthesia introduced by Mr. ltobert Ellis, under the above title, are perfectly carried out in the construction of the Inhalers described in this paper. These are thus stated in his recent work on the ‘ Safe Abolition of Pain.’ * First. Entire security against the excessive action of either of the anaesthetics. Secondly. The production of a modified anaesthesia, varying at tlie will of the operator, from a mere feeling of exhilaration to the deep unconsciousness requisite for abolish- ing acute pain. Thirdly. The power of maintaining this state of anaes- thesia at the same degree for any requisite period, or of modifying it according to arising exigencies. Fourthly. The reduction of the dose of chloroform to its lowest practicable point. Fifthly. The partial substitution for it of a vaporous basis of mixed alcohol and ether, whereby its properties are enhanced and sustained, and its dose diminished without abatement of its value as an anaesthetic. Sixthly. The counteraction of the heart-depressing power of chloroform, by combining it with a heart-stimulant, and * ‘ Oil the Safe Abolition of Pain in Labour and Surgical Operations.’ Robert Hardwicke, 192, Piccadilly.
