Notes:
   ¹  Although not specifically stated in the paper, it is assumed that the mole fraction solubility, x, is for a total pressure of 101.325 kPa.
   ²  The solubility corresponding to a gas partial pressure of 101.325 kPa was calculated by the compiler; Raoult's law was assumed to apply to the mixed solvent solution.

Method/Apparatus/Procedure:
   A glass apparatus was employed in which the uptake of gas by a known volume of solvent in a dissolution cell was volumetrically determined. The gas was displaced by mercury as the gas dissolved at constant pressure. A magnetically operated gas circulating pump and bubbling tip were provided for bubbling the gas through the solvent in the dissolution cell.

Source and Purity of Materials:
   Sources and purities not given.

Estimated Errors:
