It is announced that the successful liquefaction of oxygen which,

as we mentioned last week, was effected at Geneva a fort- night ago by M. Raoul Pictet, has been almost immediately fol- lowed by the liquefaction of hydrogen and nitrogen gas and of noninion atmospheric air. This, it is said, was effected by M. Chilletet, in the presence of three members of the Institute of France, on Monday last, the last day of 1877. Thus no gas re- m:Nina which cannot be condensed into the liquid state under an adequate pressure and with sufficient arrangements for the lowering of the temperature.
