Method/Apparatus/Procedure:
   Differential scanning calorimeter. Mixtures (1.5 - 2.0 mg) of known concentration were weighed into aluminum pans, which were then crimped to preclude sample loss during the heating process. Solubilities determined by measuring melting points of binary mixtures using a Perkin-Elmer DSC-2 differential scanning calorimeter and scan rate of 5 K/min.

Source and Purity of Materials:
   (1) Gold Label, 99.9+ %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, used as received.
   (2) 99 %, Aldrich Chemical Company, was vacuum-distilled before use.

Estimated Errors:
   Solubility: x₁: ± 0.0003 (compiler).
   Temperature: T/K: precision ± 0.3 (compiler).
