Abstract
As part of an investigation on the mechanism of conduction of organic substances1, we have now investigated the dependence on temperature of the electrical resistivity of phenothiazine. For lack of independent criteria of the purity of the substances under investigation, and in the absence of a thorough knowledge concerning the effect of impurities on the electrical properties, it has been our practice to carry out resistivity measurements on a number of specimens of the same substance in various stages of purification. These measurements were made on disks of polycrystalline materials which had been compacted under pressure prior to the measurements.
