A modified vibrating-electrode apparatus designed for the reliable measurement of air-water and oil-water adsorption potentials is described. The equipment is capable, under the best conditions, of measuring potential differences of 0.2 mV at the air-water surface and of 0.5 mV at the oil-water interface. The surface potentials of small quantities (0.1 ml.) of aqueous solutions may be measured rapidly to a lesser degree of accuracy.
