Using the ultrasonic pulse method, the velocity of longitudinal waves in metallic beryllium has been measured from 300°K to 23°K, and transverse waves from 300°K to 3°K. The adiabatic moduli and compressibility have been computed from the velocities. A new technique for affixing the quartz transducer to the solid for ultrasonic measurements, in suitable solids, below 100°K, has been successfully employed for the measurements in beryllium.
