✦ Synopsis

DURING the last few years we have carried out some measurements on the velocity of sound in liquid argon, liquid oxygen, and liquid nitrogen I-3 in order to obtain thermodynamic data. The earlier experimental arrangement, consisting of an interferometer with variable path length, limited the allowable pressure to about 75 kg/cm 2. In that range the pressure dependence was nearly linear. In order to extend this pressure range appreciably we developed a new apparatus with a fixed path resonator, and new measurements were carried out in liquid nitrogen and liquid argon. These results are compared with those obtained by other authors.
