The onset of solidification of /sup 4/He in porous Vycor is identified from changes in transverse sound velocity. From observed overpressures required to initiate freezing (ranging from 18 bars at 1.3 K to 30.7 bars at 2.38 K), the interfacial energy between liquid and solid /sup 4/He was estimated. The superfluid transition up to 35.5 bars was also observed.
