COTTON PROCESS ETHER is a physical mixture of pure sulphuric ether, carbon dioxid and ethylene, compressed for convenience sake as well as for economy, into liquid form. The difference in diffusibility of the gases it contains is such that, upon the opening of the package to pour the liquid into an anesthetizer or to use by drip upon the usual open cone, a great deal of the gas of highest volatility is dissipated into the atmosphere and the value of the original mixture lessened in just that degree.
