Notes:
     Phase diagram depicted in paper shows a simple eutectic system.

Method/Apparatus/Procedure:
   Temperatures of solid-liquid equilibrium were determined by the synthetic method. Weighed amounts of the two components were sealed in tubes, temperature slowly varied until a mean temperature was found at which a small crystal of the solid phase remained unchanged.

Source and Purity of Materials:
   (1) Purity and chemical source were not specified in paper.
   (2) Purity and chemical source were not specified in paper.

Estimated Errors:

   Temperature: T/K: precision ± 0.3 (compiler). x₁: ± 0.005 (compiler).
