  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Osmose  \Os"mose\,  n.  [Gr.  ?,  equiv.  to  ?  impulse,  fr  ?  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. 
  The  more  rapid  flow  from  the  thinner  to  the  thicker  fluid 
  was  then  called  endosmose,  and  the  opposite,  slower 
  current,  exosmose.  Both  are  however,  results  of  the  same 
  force.  Osmose  may  be  regarded  as  a  form  of  molecular 
  attraction,  allied  to  that  of  adhesion. 
  b  The  action  produced  by  this  tendency.
