Thermoelectric Effect in Single Crystal Zinc Wires

The work reported is a continuation of measurements published in the Physical Review for October, 1925. The thermol e.m.f. of the zinc crystals against copper has been measured from -182°C to 480°C for crystals having orientations from about 10° to 90°. The relation between thermoelectric power and temperature is definitely not linear, but may he represented fairly well by a second degree equation. The nature of the effect in the neighborhood of the melting point will be discussed
