other equations for W, in each case mixing threeHghts from different parts of the spectrum in suitable proportions. By-eliminating W from each of these equations he obtained the sensation-values of 14 positions in the spectrum in terms of the sensation-valuesof the three standard colours, R, G, B.… … Red. Blu.e. Fig. 58. Clerk-Maxwells sensation curves. The dotted line is the algebraical sum ofthe ordinates at each point; it is not a true luminosity curve. Abscissae, wave-lengths of the prismatic spectrum of sunlight; ordinates, arbitrary scale. (Clerk-Maxwell.) Papers followed by J. J.…
