• The transport number of the ions, <I>t</I><SUP>±</SUP>, of (C<SUB>2</SUB>H<SUB>5</SUB>)<SUB>4</SUB>NClO<SUB>4</SUB>, NaClO<SUB>4</SUB>, NaCl, KCl, and HCl in <I>N</I>,<I>N</I>-dimethylformamide(DMF)–water solvents were determined by the agar–salt bridge method. In order to compare this method, <I>t</I><SUP>+</SUP>(HCl)'s in DMF–water media were measured by both the Hittorf method and the concentration cell method. Good agreement among these methods leads to the conclusion that <I>t</I><SUP>+</SUP>(KCl) and <I>t</I><SUP>−</SUP>(KCl) are nearly equal in the whole range of DMF–water media. The results suggest that potentials obtained in nonaqueous polarography with the bridged SCE by correcting the bridge potential with a slow flowing type aqueous SCE are always referred to the ordinary aqueous SCE.
