Since freezing is suppressed in small pores such as those of Vycor, superfluidity occurs at substantially higher pressures than in bulk 4He. Ultrasonic measurements show that the amount of superfluid in the pores does not decrease until freezing begins at a pressure of about 36 bar. At slightly high
