Note 247 — Chapter VII · PHYSICAL OR HETEROGENEOUS EQUILIBRIUM.—THE COLLOIDAL CONDITION
Reading edition
Before Graham's time, and for the few colloidal liquids then known, this view was held by such men as J. B. Richter, Berzelius and Faraday (loc. cit.) (cf. Wo. Ostwald, loc. cit., p. 19). The first extended experimental investigation in support of it was made by Barus and Schneider, Z. phys. Chem., 8, 278 (1891). Bredig was also an early and consistent champion of this view (vide his Anorganische Fermente, 1901).
