✦ Synopsis

Variations of Gaseous Compressibility.--E. H. Amagat describes his experiments with various gases under extraordinary pressures. He finds that the greatest wtriations from the acti(m of hydrogen are fbund ill the g~ses which are nearest liquefaction, This is shown very clearly by the curves of formene and ethylene. Nitrogen and eart)onlc oxide show nmch smaller variations; those of oxygen are more considerable. The variations of air are intermediate between those of" its constituent gases; the oxygen and nitrogen seem to be compressed separately, as if they were entirely independent of each other. The minimum ordinate of air is situated l)etween the analogous • ,ordinates of oxygen and nitrogen and sensibly nearer tlmt of' the latter gas.--Ann, de Chim. et de Pl~y,.
