  osmosis \os*mo"sis\ ([o^]z*m[=o]"s[i^]s), n. [NL., fr. Gr.
     'wsmo`s, equiv. to 'w^sis impulse, fr. 'wqei^n to push.]
     (Chemical Physics)
     (a) The tendency in fluids to mix, or become equably
         diffused, when in contact. It was first observed between
         fluids of differing densities, and as taking place


         through a membrane or an intervening porous structure. An
         older term for the phenomenon was {Osmose}.
  
     Note: The more rapid flow from the thinner to the thicker
           fluid was then called {endosmosis} (formerly
           {endosmose}), and the opposite, slower current,
           {exosmosis} (formerly {exosmose}). Both are, however,
           results of the same force. Osmosis may be regarded as a
           form of molecular attraction, allied to that of
           adhesion. See also {osmotic pressure}.
     (b) The action produced by this tendency.
