The electrical resistivity rho of the heavy-electron superconductor UBe/sub 13/ has been measured at temperatures T between 0.1 and 300 K for pressures P to 16 kbar and in magnetic fields H up to 9 T. The temperature T/sub max/ at which rho shows a maximum increases linearly with P at H = 0 and with H/sup 2/ for P = 14.8 kbar. The resistivity, when normalized to its value at T/sub max/(P), scales as a function of reduced temperature T/T/sub max/(P) from 1 K to --1.4T/sub max/. At P = 14.8 kbar, the magnetoresistance -(R(H)-R(0))/R(0) behaves as a universal function of H/T for 1less than or equal toTless than or equal to6 K and 0
