 Method/Apparatus/Procedure:
   Experimental procedure not given in the reference. Compiler speculates that the experimental values were, in all likelihood, determined by a gravimetric method, which was common practice during this era. The method probably involved equilibrating excess solute and solvent in sealed containers, transfer of weighed aliquots of saturated solution to tared containers, evaporation of solvent, and weighing of solid residue  that remained.

 Source and Purity of Materials:
   (1) Purity and chemical source not given. Paper states only that the solute was carefully purified.
   (2) Purity and chemical source not given. Paper states only that the solute was carefully purified.

 Estimated Errors:

   Temperature: T/K: ± 2 (by compiler). x1: ± 8 % (relative error, by compiler).
