    Thus there is some risk that a problem may be considered to be solved, when there yet remains a great deal to be found out. “Classical and “Colloidal Chemistry The opposition made by Prof. Jacques Loeb between what he calls colloidal ” chemistry and “ classical ” chemistry is a puzzle to me. At first, it seemed that theories relating to heterogeneous systems were to be excluded from application to colloids. But we find osmotic pressure and the Donnan membrane equilibrium freely made use of in Prof. Loeb’s work. It might indeed seem to some that the latter is strained to breaking point. Also, phenomena due to aggregation, while not looked upon with favour, are recognized. Finally, the only difference turned out to be the existence of adsorption, which is not to be mentioned in the discussion of colloids. We have seen reason to believe in its genuine occurrence where surfaces
