Notes:
   ¹  Calculated by compiler.
   ²  Plasma was obtained by centrifugation of the dog blood.
   ³  The hemoglobin solution contained 8.5 g purified hemoglobin in 100 cm³ of solution.

Method/Apparatus/Procedure:
   A glass bubbling-type of saturator immersed in a constant temperature bath was used. A known volume of saturated solution was transferred over mercury into a Van Slyke desorption apparatus. Gas removed in three evacuations was transferred to a sample tube where the volume was determined and a sample of the gas was analyzed. Solubilities were determined at several pressures below atmospheric and above atmospheric and expressed as Ostwald coefficients.

Source and Purity of Materials:
   1. Ethene source and purity not given.
   2. Heparin was used as a blood anticoagulant.

Estimated Errors:
   Solubility: δL/L = ± 4% (compiler)
   Temperature: δT/K = ± 0.05
