Method/Apparatus/Procedure:
   To a known volume of m-xylene small portions of alcohol were added. After each addition of alcohol, water was added until a distinct milkiness was observed. The mixture was kept at constant temperature and was shaken repeatedly.

Source and Purity of Materials:
   (1) Source not specified; "absolute" ethyl alcohol; used as received.
   (2) Source not specified; "nearly pure" m-xylene; used as received.
   (3) Distilled.

Estimated Errors:
   Solubility: Not reported.
   Temperature: Not reported.
