Application of the Interferometer to Gas Analysis. J. D. EDWARDS (Chtem, and M e t . Eng., 1919, 21, 56&565).-The gas interferometer measures the difference in refractivity of two gases of binary mixtures. Usually, one of the components is taken as the standard gas, and the difference in refractivity of the mixture and one of ita components is determined. For a change of a% of one of the componenta the change in refraotivity AB = 2731 T , p / 7 6 0 . a/ 100(R, -R2).
