The temperature variation of the superfluid density has been measured for /sup 4/He films adsorbed on porous Vycor glass. Films with transition temperatures ranging from 0.1 to 1.5 K were studied. Apart from a small rounding on the order of 5 x 10/sup -3/T/sub c/, the superfluid density of these films follows a power law near the transition similar to bulk helium.
