• The temperature variation of ultrasonic velocity has been studied in a number of liquids down to the temperatures of -100℃ by extending the fixed-path double-crystal interferometer for such a type of study. Non-linear variation of ultrasonic velocity with temperature has been observed in some cases near the melting point. A relation has been proposed between melting point T_m and dV/dT and is tested using the data for organic liquids, associated liquids and molten metals. New relations between the melting point T_m and the temperature coefficients of ultrasonic velocity, density and adiabatic compressibility following the theoretical relations of Nomoto are obtained and are examined in the light of the experimental data.
