Abstract
IN order to explain some recent high-frequency (430Mc./s.) measurements by Cownie and Palmer1 on the variation in the dielectric constant of moist clay with water content, it was assumed2 that the dielectric constant of the water increased exponentially from 3 (the high-frequency value for ice) at the water – clay boundary to 80 (the normal value for water) at an infinite distance from the boundary. It was supposed that the maximum change occurred in the thin layers of water close to the solid, and that the effects extended into the bulk of the liquid for appreciable distances.
