 Method/Apparatus/Procedure:
   The measuring apparatus was described by Brown et al. (ref. 1). Iodomethane gas was admitted to the measurement apparatus from a storage bulb by distillation. The gas volume absorbed by water was determined using a gas buret. The temperature was controlled  by a water bath and the equilibrium was aided by a magnetic stirrer in the equilibration bulb. The concentration in the solution was calculated from the pressure and volume measured.

 Source and Purity of Materials:
   (1) Eastman Kodak Co., redistilled before use.
   (2) Double distilled.

 Estimated Errors:
   Solubility: ± 3 %.
   Temperature: ± 0.01 K.
   Pressure: ± 0.05 mmHg.
