 Method/Apparatus/Procedure:
   The equipment and a manometrical procedure for solubility measurements were similar to those of Lundberg et al.1

 Source and Purity of Materials:
   PMMA (Lucite) used is a product of du Pont de Nemours Co.: ρ = 1.20 g/cm3.
Gases from Air Reduction Co., had a minimum purity: CO2 – 99.5 %; N2 – 99.90 %; Ar – 99.997 %; He – 99.99 %.
Gases (Matheson Co), included as impurities: Ne–14 ppm He, Kr–12 ppm N2 and 23 ppm Xe.

 Estimated Errors:
   Solubility: δC/C ≤ 8%.
