<p>In a previous communication the results of an investigation of the constant of spectral radiation of a black body were presented. The position, lambda /sub /b m// of the maximum emission E/sub /b m// was computed by taking the wave-lengths lambda /sub 1/ and lambda /sub 2/, corresponding to equal intensities E lambda /sub 1/ = E lambda /sub 2/, on the assumption that the observed energy curve fits the Planck equation. The equation used in computing lambda /sub /b m// requires a knowledge of the constant C, and the value taken was C = 14,500. A new, and apparently more reliable calibration curve of the fluorite prism used in the work, and the discovery of small errors all
