623) chloroform, c, water, ■w, and ether, e, the water may be considered as the partition. Ether, being freely soluble in water, diffuses into it and reaches the sur- face of c. Being also soluble in chloroform, it moves on from this surface, diffusing in the chloroform. The chloroform, being only slightly soluble in water, diffuses into it but slightly. Finally, there remain only two mixtures: the water saturated with ether and chloroform, and the chloroform saturated with water and containing... the rest of the ether. This experiment illustrates not only the solvent action of the partition, but also the way in which the relations of solubility between the partition and the liquids Fig. 623. — Diagram : c, that it separates determine the dominant direction chloroform ; w, water ; c, ether, of diffusion. The cell wall raembrane. — Among the plant membranes through which solutes pass, the cell wall seems to exercise little selective influence. It is permeable to most if not all substances presented to it in nature.
