Methylene blue shows an anomalous wave on the polarogram in addition to the one which might be expected on the basis of potentiometric data. The influence of temperature, the concentration of methylene blue and the effect of eosine on the anomalous wave were studied. The results are follows; 1) The anomalous wave appears when the pH of the solution is higher than 4.5. 2) The difference of the half-wave potential of the main wave and anomalous wave changes with. the concentration of methylene blue and does not depend on the pH of the solution. 3) The ratio of the anomalous wave to the total wave-height becomes smaller when the temperature of the solution increases. 4) The anomalous wave is greatly suppressed, by the presence of eosine and the main wave appears on the polarogram even when the concentration is ca. 2.9×10-5 molar.
