   b  Calculated by F. W. Getzen.

 Method/Apparatus/Procedure:
   The saturated solution was prepared by shaking the substances in a thermostat bath for at least 12 hours. An interferometric method was used for the analysis of the saturated solution (1). Samples were withdrawn from several saturation flasks and read against a pure water sample in an interferometer. The concentration was established from a calibration obtained from previous measurements made with a reference solution.

 Source and Purity of Materials:
   (1) Commercial product (Eastman Kodak Co.), recrystallized twice from ethanol, m.p. 52.84°C.
   (2) Distilled water "of good quality".

 Estimated Errors:
   Solubility: ± 5 % (authors).
   Temperature: ± 0.01 K. (authors).
