Abstract
When Burch (1898 and 1900) fatigued the human eye by exposure to sunlight through a suitable colour filter, he found evidence for four sensations: red, green, blue and violet, but not for yellow. Edridge-Green and Marshall (1909), after exposing the eye to sodium light, stated that they found definite evidence for a separate yellow sensation. I have recently repeated these experiments, with certain modifications which will be described, and I have arrived at the same conclusion as Edridge-Green and Marshall.
