Notes:
1
Calculated by compiler.
2
Water content of blood samples was determined by drying overnight at 110 °C and determining loss in weight.
3
Blood lipoids were extracted from blood corpuscles with ethyl ether and petroleum ether.
Method/Apparatus/Procedure:
A glass bubbling-type of saturator immersed in a constant temperature bath was used. The gas was presaturated with water vapor. 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. The solubilities were expressed as the Bunsen coefficients.
Source and Purity of Materials:
1. Ethene source and purity not given.
2. Heparin was used as a blood anticoagulant in all cases.
