Accurate measurements of the electric resistance of zinc were made by the potentiometer method in the range of temperature from room temperature up to 350℃. The anomalous changes were observed at the temperatures, 170, 200, 230 and 320℃. The first two temperatures were explained respectively to be the eutectic temperatures of the solders, Pt-Sn-Zn and Sn-Zn systems, used to solder the potential lead and the specimen ; 230℃ to be the temperature of second separation in the former solder ; 320℃ to be the eutectic temperature of the alloy, Pd-Zn system formed in the specimen. From a conception explaining the eutectic phenomenon, 170°, 200°and 320℃ were considered to be anomalies of zinc itself.
