Method/Apparatus/Procedure:
   No experimental details given in paper. Compiler speculates that the transition temperatures were probably determined by visually observing the temperature corresponding to the first crystal formation (or complete liquefication).

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: ± 0.002 (compiler).
