For the theoretic exposition of osmotic pressure, no further attention need be paid to the membrane than to postulate its semi-permeability. It is, however, desirable that the physical properties of the membrane should not be lost sight of, especially from the experimental point of view. Leaving out of account for the moment the mechanical requirements of a rigid membrane, let us imagine a system in which we have a solution separated from the pure solvent by a thick layer of another liquid which can take up or dissolve the solvent, but not the solute.
