Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by noting the temperature at which the last trace of solid solute disappeared. Solubilities at 298 K interpolated from experimental values using in $x_{1}$ versus 1/$T$ graph.
