Abstract
IN studies of the composition of vapour in equilibrium with liquid mixtures of the atmospheric gases at pressures near 1 atmosphere, a method of procuring a continuous circulation of the vapour was needed. Any pump incorporated in the system was required to operate without changing the volume of the vapour space. It was further specified that the materials from which it was constructed should not adsorb large quantities of the vapour.
