This theory, as stated by Mrs. Ladd-Franklin, supposes that the rods are the organs for brightness vision alone. As the visual purple is situated only in the rods, any increased effect of light of a particular wave-length, due to its absorption by the visual purple, will cause the stimulus to appear relatively darker or lighter, and possibly more or less saturated, but can in no way produce a change in color-tone. It would seem quite possible for the Hering theory to make use of the explanation just given for the Purkinje phenomenon, by simply considering that the black-white substance alone exists in the rods while the two color substances, as well as the black-white substance, are to be found in the cones. If the color and brightness substances were arranged in this way, any absorption of colored light by the rod-pigment would intensify the effect of the color stimulus on the black-white substance and so increase the relative brightness of the color. But, even with this modification, the Hering theory seems to offer no explanation of color changes based on anything but a change in the wavelength of the stimulus. At present we have only one hypothesis to suggest as a possible explanation for our results. This is that different intensities or brightnesses of stimulus are required for the excitation of the different color substances--i. e., that a stimulus must possess a certain range of brightness, as well as a certain range of wave-lengths in order to be effective in arousing an activity in a certain color substances, and that the brightness required for the various color substances differs for the different colors at the long wave end of the spectrum.
