We have determined the effect of hydrostatic pressure on the susceptibility, on the T/sup 2/ temperature dependence of the spin-fluctuation resistivity, and on superconductivity in UPt/sub 3/. The spin-fluctuation temperature T/sub s/, derived from the slope of resistivity versus T/sup 2/, is used within a Fermi-liquid picture to calculate the susceptibility chi at T = 0 K. The depression of this calculated chi with pressure agrees with the directly measured value partial lnchi/partialP = -24 Mbar/sup -1/. Both the superconducting transition temperature T/sub c/ and the initial slope of the upper critical field also decrease under pressure. We find that partial lnT/sub c//partialP = -25 Mbar/sup -1/ and speculate upon correlations between chi and T/sub c/.
