Another Anaesthetic

No sooner have the anaesthetic merits of ethylene been successfully demonstrated by Chicago physiologists than another candidate for sleep producing honors arises in Germany. A writer in The London Lancet describes an anaesthetic discovered by Professor K. Gauss, of Freiburg, composed of 40% purified acetylene and 60% oxygen, deodorized by oil of pine. Already more than 500 operations are said to have been performed under it with no harmful results.
