The electrostatic voltmeter described in this paper consists, from an electrical standpoint, of two meters which may be used in series or in parallel. Mechanically, however, it is essentially a single meter, since it contains only one moving part. With the parallel connection voltages between 15 and 100 kv may be measured to within .1 of 1%. With the series connection and voltages between 100 and 200 kv (one‐half on either side of ground, the halves fairly well balanced) the error need not exceed .1 of 1%.
