Notes:
     Compiler: Eutectic point occurs at about x₁ = 0.447 and T/K = 310.6.

Method/Apparatus/Procedure:
   Binary mixtures prepared by weight. While the experimental details were not given in the paper, compiler speculates (based upon quantity of material used) that the sample was sealed in a glass container, temperature slowly varied, and the phase diagram determined by visually noting the temperature at which the last/first crystal of solid disappeared/appeared.

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 ± 0.2 (compiler). x₁: ± 0.002 (compiler).
