 Method/Apparatus/Procedure:
   Experimental procedure only marginally described by author.
Excess solute and solvent were equilibrated in a constant temperature water bath for between 10-30 minutes. Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity. Author noted that evaporation to dryness and weighing the residue was subject to too much decomposition.

 Source and Purity of Materials:
   (1) Purity not given, Kahlbaum, was recrystallized from toluene to a melting point temperature of 100.4 ºC.
   (2) Marked absolute, from Eimer and Amend and Chas. Cooper and Co., dried over calcium oxide and distilled before use.

 Estimated Errors:

   Temperature: T/K: precision ± 0.1. x1: ± 8 % (relative error, compiler).
