The refractive indices of solutions of the alkali halides and nitrates were determined at 25 ° and from these the specific refractivities of both the solution and solute were calculated by means of the Lorenz-Lorentz formula. From density data the partial molal volumes were also calculated. The dielectric constants of the solutions were calculated by means of the Huckel relation involving the refractive index and were found to decrease with increase in concentration, the values for all salts approaching the same small value at saturation. The activities were calculated according to the equation given by Huckel for concentrated solutions of strong electrolytes and were found to agree qualitatively with experimental values.
