In a recent publication we presented the results of some measurements of the specific heat of liquid 3He/4He mixtures at saturated vapor pressure near the interesting junction of the lambda and phase-separation curves which occurs at a temperature T0 ≅ 0.87° Kand a 3He mole fraction x0 ≅ 0.67.1 The purpose of the present report is to indicate some of the possibilities for determining a variety of thermodynamic information about the junction region from the specific heat data.
