The color processes caused by monochromatic lights of equal energy were investigated and expressed in terms of zeta-time curves which indicate the time-course of electrical excitability following a brief illumination.
1. Comparison was made on zeta-time curves obtained at the fovea and at 20° from the fovea.
2. Zeta-time curves for two kinds of white light from sources A and C of the ICI were compared.
3. Curves of direct and indirect induction were investigated at the fovea.
