   ^a  Calculated by the compiler.
   ^b  L = Ostwald coefficient [cm³ cm^-3]

Method/Apparatus/Procedure:
   The apparatus was essentially similar to that of Geffcken (Ref. 1) except that the manometer tube was longer.

Source and Purity of Materials:
   (1) Purity 99.42 mole %.
   (2) Degassed by boiling.

Estimated Errors:
   Solubility: δL = ± 0.25 %
   Temperature: δT/K = ± 0.1
