The vapor passes into the bottle n,which is partly filled with ice, and the incondensiblegases pass out through m. It is a transparent liquid,specific gravity , of a very disagreeable odor; hasthe quality of dissolving sulphur and phosphorus, boilsat 100°, and does not freeze at —60°. It is very vola-tile, and produces an intense cold during evaporation invacuo, —80° being reached. Its principal point of in-terest is the powerful refractive and dispersive power itexerts upon light, a .property which renders it especiallysuitable for making prisms to be used in is also used as
