    emulsoids and has been measured in some cases. Now if we take the series of salts with different anions comprised in the Hofmeister series, we find that their relative effect on swelling is in the order of their action on certain properties of water expressed in compressibility, surface ten- sion, and so on. Schryver showed that a similar state of affairs is present in the dis- persion of colloids such as globulin, as also in the displacement of the temperature at which a mixture of phenol and water becomes homogeneous (the “ critical solu- tion temperature ”). Difference in degree of adsorption of these various anions may well have a notable effect on the properties of water at the interface and lead to modifi- cations in the amount of water present in the more solid phase, as pointed out by Hatschek and by Freundlich. But whatever may be the mechanism, the important fact is that the capacity of taking up water reversibly by the colloids of the cell may be regulated by such agencies as free electrolytes. 7
