URING the course of other work it became desirable to consider qualitatively the miscibility of a selected group of organic solvents. Since information of this type is infrequently encountered, the observations of this survey have been tabulated in t,he tables presented herewith. The classifications were made by shaking together 5 ml. of each of the solvents listed in a test tube for 1 minute, then allo~ving the mixture t o settle. If no interfacial meniscus was observed, the solvent pair was considered miscible. If such a meniscus \vas present, the solvent pair was regarded as immiscible. The classification of immiscible is a qualitative one since solvent pairs may exhibit some degree of partial miscibility while existing as separate phases. Solvent pairs possessing a pronounced degree of partial miscibility are designated by the symbol Is. The solvents examined viere of reagent grade when available. Some of the less common ones were obtainable only in practical grade. No attempt was made to dry or purify these.
