An arrangement of condensers, switches, and a ballistic galvanometer is discussed, by means of which high D.C. potential difference can be measured with considerably greater precision than given by ordinary high voltage electrostatic voltmeters. Simple equations of design are derived, which if scrupulously followed will give 0.5% (and greater) accuracy no matter how high the D.C. potential difference. The application of this method to the calibration of an electroscope is given in detail.
