The osmotic pressure of ${\mathrm{He}}^{3}$-${\mathrm{He}}^{4}$ mixtures has been measured down to 0.027\ifmmode^\circ\else\textdegree\fi{}K. The results are used (a) to check the validity of the ${\mathrm{He}}^{3}$-${\mathrm{He}}^{3}$ effective interaction deduced from transport data using recent exact solutions of the Boltzmann transport equation, (b) to obtain the limiting solubility of ${\mathrm{He}}^{3}$ in ${\mathrm{He}}^{4}$ as a function of pressure, and (c) to demonstrate the metastability of supersaturated mixtures of ${\mathrm{He}}^{3}$ in ${\mathrm{He}}^{4}$ in the absence of a free surface.
