The absolute thermoelectric power S of gallium single crystals has been measured over the temperature range 10-200°K. The anisotropy usual with this metal is again evident. At higher temperatures the S-T curves are linear with positive values of S; as the temperature falls below about 60°K phonon-drag effects become increasingly important, giving negative values of S. Phonon-drag peaks occur at 16·5, 23 and 15°K, respectively, in the (100), (010) and (001) crystallographic directions.
