Abstract
THESE lectures are two in number, and the lecturer devoted the first to his views of colour-vision and colour-blindness, the second to the means of detecting colour-blindness from a practical point of view. The first lecture describes Dr. Edridge-Green's explanation of colour-vision, for which he indicates visual purple as an essential factor. A large portion of the lecture is devoted to the visual purple and describes various phenomena which he has observed in reference to it. The “pros” are well given, but the “cons” are more or less absent. It is the latter which have led other investigators to reject the idea that this sensitive matter can fully explain the different phenomena which occur in colour-vision and colour-blindness. The true function of visual purple has to be further investigated. The part of the lecture which is devoted to a description of Dr. Edridge-Green's theory of colour-vision has been presented to the public in various publications. We need scarcely summarise the theory. It is one of several theories which have been propounded by different investigators, and, like all, is open to criticism.
