The work described in this paper was suggested by the results of earlier work done in this laboratory in an endeavour to elucidate the fundamental causes of power loss in dielectrics subjected to alternating stress. The work referred to has been described in three papers (Jackson 1935; Sillars 1938; Pelmore 1939) and refers to the dielectric characteristics of mixtures of paraffin wax with small amounts of long-chain aliphatic esters. It was shown in these papers that the observed dielectric losses can be interpreted in terms of the Debye theory of polar molecules and that the molecules probably rotate as rigid rods: this conclusion was based on a study of the effect of the chain lengths of the molecules of the polar and non-polar constituents of the system.
