Method/Apparatus/Procedure:
   The synthetic method was used. Miscibility was determined in a glass-stoppered tube of 4 mm inside diameter. Equal volumes (0.1 mL) of (1) and (2) were measured into the tube which was then strapped to a thermometer, warmed to 5 or 10 °C above the solubility temperature, mixed well by shaking, and then allowed to cool slowly, still shaking, in a bath of white oil (above 30 °C), water (below 30 °C), or nonfreezing mixture (below 0 °C).

Source and Purity of Materials:
   (1) Not specified.
   (2) Some aromatic hydrocarbons(*) obtained from Mr. J. B. Conant, Harvard University; others were purest commercial samples.
