- Absorb mentally - 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. - The action produced by this tendency.
