✦ Synopsis

In order to compute the dominant wave-length and purity of a color stimulus by means of the "excitation" data of the Optical Society of America, two values must be obtained by interpolation. The adoption of the osculatory formula for this interpolation permits the computations to be made with perfect reproducibility. Each of the O. S. A. curves by this method is represented as a series of parabolas of the fifth degree which join at the values specified at every IO millimicrons so as to have a common slope and curvature at the junction point. Interpolated values have been computed according to this formula for every millimicron. Tables giving these data will be published in the July number of the Bureau of Standards Journal of Research.
