Method/Apparatus/Procedure:
   Solutions made up by weight and density measured but not reported in paper. Equilibrium established between a measured volume of gas and a measured amount of gas-free liquid in a cell fitted with a magnetic stirrer. Amount of gas absorbed estimated from change in volume of gas. Details in source.

Source and Purity of Materials:
   1. Commercial sample, minimum purity 99.6 mole per cent.
   2. Analytical grade.
   3. Distilled and degassed.

Estimated Errors:
   Solubility: δα = ± 0.2%. (estimated by compiler)
   Temperature: δT/K = ± 0.2 (estimated by compiler)
