attenuation processes become more important with increasing frequency, and at high frequencies the wave amplitudes in the crystalline region are too small to be measured with sufficient accuracy. The most favorable conditions for investigating the frequency response of the interface would be in systems with high thermal conductivities and small kinetic constant p. In our experiments on tin, the frequency range available for measurement was limited, from 0.05 to about 1.3 rad/sec, the upper value being determined by loss of sensitivity due to attenuation effects in the solid and liquid regions. Most of the data were taken at the lowest frequency (~0.05 rad/sec) where temperature amplitude measurements were more accurate. However, as can be seen from the computed curves of D. A. RIGNEY~
