Abstract
SOME time ago, in a communication from this Department1, it was shown that a steadily increasing exposure to X-radiation produced alternate increases and decreases in the electrokinetic potential of certain colloid particles. The colloid used at the time (a dilution of 'Aquadag' in water) is peculiarly stable, and at no stage were there any signs of coagulation. It was thought possible that with a more sensitive colloid the decrease in potential at the minima of the curve might be sufficient to bring the colloid to its flocculation point, and at my suggestion Dr. Liebmann and Mr. Jones have been working with certain pure gold sols.
