Abstract
An increase in the usefulness of the recording polarograph is obtained by a modification which allows either a-c. or d-c. polarograms to be obtained from it. A description of such a modification performed on the Sargent Model XXI is given in detail. A comparison of a-c. and d-c. polarography is made and illustrated by polarograms obtained from this instrument.
