The NMR spin-lattice relaxation time, T 1, of a degenerate submonolayer coverage of 3He on thin 4He films has been measured. As a function of the 4He coverage, T1 exhibits a maximum, and crosses over to a region with an anomolous temperature dependence at higher coverages.

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
