The arrangement used by Richards and Forbes, while probably accurate to of a volt, was complicated and involved troublesome calibrations. Moreover, it seemed desirable to dispense with the one-volt element and compare the drop of potential directly with a standard Weston cell. The arrangement finally adopted is shown in fig. 5.
