IN the course of an investigation of hue discrimination in the para-central parts of the human eye1, this property was measured also in the fovea at an intensity level of 0.95 e.f.c. The test field was bipartite, subtending an angle of 50′ at the eye, and surrounded by a white field (6°); the latter was separated from the test field by a black line.
