   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 heavy water was determined in the 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 of the solution was calculated from the pressures and volumes measured.
