Electrical measurement of physical values: The determination by electrical and magnetic means of quantities not in themselves of an electrical nature

THIS paper was prepared under instructions from the Committee on Instruments and Measurements, with a view to forming a basis for the Committee´s work in connection with electrical measurements as applied outside of the strictly electrical field. The system of classification used is in accordance with the nature of the quantity under measurement, rather than with the principle involved; and the subject is treated under nine headings.
