Abstract
EXPERIMENTS conducted in the research laboratory of the firm of Adam Hilger, Ltd., by Mr. G. M. Fleming show that, in certain circumstances, distinct differences of refractive index may occur in certain liquids at the separating surface between the liquid and a polished glass surface. In a few exceptional cases the differences are very great; in the case of ether, for instance, they may amount to as much as 0.02 in the refractive index.
