SECTION 11. Asymmetrical Flicker. SECTION 111. SECTION IV. General Conclusions. The physiological initial stages of the reaction generated in either component of a pair of ' cmaponding retinal points' proceed without touching any of the apparatus of the twin point. Only ayter sensations initiated ?om the right and Zej 2 'points' have been elaborated, and have reached a dignity and de@itms renaking them well amenable to introspection, does interfweme between the reactions of the two (left and n'ght) eye-system OcCuT. Xince lej2 and right end-reaults emerge pure, hyhridisatimi cannot have mixed the early stages in their evolution. The binocular sensation attained seems contbined jkm right and left unwcdar seneations elaborated in&-iDendently. THE following experiments attempt inquiry into the influence exerted on the reactions of a 'retinal point' by certain forms of activity at the 'corresponding point' of the other retina. 1 The experiments were the subject of a brief communication to the Royal Soaiiety's
