A novel method for the measurement of the variation of thermal resistivity with temperature on small specimens, together with the results of tests that establish the validity of the method,ARE DESCRIBED. The method is applied to the binary alloy Cu3Au over the temperature range 133 to 406 C. Measurements of the variation of electrical resistivity of the same material with temperature between 33 and 420 C, obtained by a conventional method, are also reported. Procedures for deducing the dependence of physical properties upon order from such observations are critically reviewed. It is shown that the behavior of thermal resistivity differs widely from that exhibited by length, Youngs modulus and electrical resistivity. Author
