The phase-separation and superfluid-transition temperatures of - liquid mixtures have been investigated as functions of concentration under conditions of saturated vapor pressure by means of dielectric-constant and thermal-equilibrium time-constant measurements. The line, which divides the normal and superfluid phases in the temperature-concentration plane, is found to intersect the phase-separation curve at its peak.
