New determinations have been made of the dielectric constants of benzene, cyclohexane, dichlorethane and nitrobenzene with the object of providing values of a higher accuracy than has hitherto been available for four standard liquids covering the range of values commonly required. Liquids of specially high purity were obtained with the co-operation of Professor J. Timmermans of Brussels and Dr. Herington of the Chemical Research Laboratory, Teddington, and the measurements were made by the a.c. bridge technique developed at the National Physical Laboratory for precision capacitance measurement and also by a cavity resonator method.
