 Method/Apparatus/Procedure:
   Samples were equilibrated for at least ten days in a water thermostat. Water analysis was done using an automatic Karl Fischer titration apparatus. The instrument accuracy was specified to be 1 %. All samples were handled with a hypodermic  syringe which was weighted before and after each addition. The instrument was calibrated using a synthetic mixture of 1 % water in methanol.

 Source and Purity of Materials:
   (1) Distilled (compiler).
   (2) Source and purity not given.
   (3) Source not given, contained less than 0.1 dissolved material.

 Estimated Errors:
   Solubility: ± 1 %.
   Temperature: ± 0.1 K.
