The thermoelectric power of single crystals of pure potassium chloride and of potassium chloride containing 107 x 10 -5 mole fraction of strontium chloride has been measured in the temperature range 561 to 693 °C, platinum electrodes being used. The results for pure potassium chloride differ substantially from the value reported by Nikitinskaya & Murin (1955) and show much less experimental scatter. A large potential produced by the crystals in the absence of a temperature gradient in the temperature range 470 to 570 °C is briefly described. From the theory of thermoelectric power proposed by Allnatt & Jacobs (1961) the heat of transport of the cation is found to be 0*99 eV and that of the anion 2 J eV in the temperature range 560 to 690 °C. Reasons are discussed for the failure of the relation proposed by Holtan, Mazur & de Groot (1953), which implies that the sum of the heats of transport should be zero for pure potassium chloride.
