Method/Apparatus/Procedure:
   Constant temperature bath and a precision thermometer.
Mixtures of known concentrations were sealed in thick-walled glass tubes and placed in a constant temperature to equilibrate with gentle rotation to thoroughly mix contents. Bath temperature was slowly increased and solubility visually determined by noting the temperature at which the last trace of solid solute disappeared. Measurements repeated  several times to verify results.

Source and Purity of Materials:
   (1) Purity not specified, Eastman Kodak Company, Rochester, New York, USA, was recrystallized several times from methanol.
   (2) Purity not given, Eastman Kodak Company, was distilled shortly before use.

Estimated Errors:
