Dutch Liquid — Chambers's Encyclopaedia

Dutch Liquid is an oily substance obtained by mixing chlorine and olefiant gases, which combine together and yield Dutch liquid, with the formula $C_2H_4Cl_2$ . It has a specific gravity of 1.271 (water = 1.000), boils at 185° (85° C), is not miscible with water, but readily dissolves in ether and alcohol. It produces Anæsthesia (q.v.), just as Chloroform (q.v.) does; but the great difficulty of preparing Dutch liquid in commercial quantities retards its employment as an anæsthetic.
