Method/Apparatus/Procedure:
   The synthetic method was used. A Reichert microscope, type RCH, equipped with a heating stage was used as described in Schmid et al.1 The disappearance and reappearance of the interface between (1) and (2) could be observed without difficulty.

Source and Purity of Materials:
   (1) Baker Chemical Co.; reagent No. 9011; n(20 °C, D) = 1.3445, d(20 °C, 4 °C) = 0.780.
   (2) Methyl, ethyl and butyl esters purchased from Applied Science Laboratories; propyl and hexyl esters, propanoate and butyrate prepared by direct esterification; other esters synthesized by transesterification; purified.

Estimated Errors:

   Temperature: ± 0.5 K.
