Abstract
Experiments are described which show that it is not permissible to ignore electrode effects in the calculation of the mobilities of ions in liquid dielectrics. Preliminary results indicate that the fall in direct current with time is due partly to electrode polarization, and partly to the removal of ions from the liquid. It has been found that for apparent field strengths lower than 1 kv./cm., the current in the dielectric is proportional to the applied potential, and there appears to be a back-e.m.f. of about one volt. Precautionary measures are suggested for future experiments.
