So far, in this memoir, we have concerned ourselves exclusively with the sensations excited by monochromatic radiations of different wavelengths appearing in the spectrum. The reason for this, as has already been explained in the first part of the memoir, is that only by such an approach is it possible to reach a correct understanding of the nature of the retinal processes which enable us to perceive light and colour. We shall now turn to the consideration of the more complex field which offers…

SummaryThe results of the present studies on the visual perceptions of polychromatic radiation support the fundamental thesis that the primary physiological sensations are those excited by

TLDR
Luminosity, colour-mixture, and hue-discrimination data for both dichromatic and trichromatic observers and to a lesser extent trichromaatic hue- discrimination and saturation data are satisfactorily explained in terms of these response curves; such an explanation leads to the conclusion that the Young-Helmholtz theory of colour vision is fundamentally correct.
A re-determination of the trichromatic coefficients of the spectral colours
Using a new trichromatic colorimeter a series of colour matches through the spectrum has been made by ten observers. The results have been averaged and a mean set of trichromatic coefficients for the
The spectral sensitivity of the fovea and extrafovea in the Purkinje range
TLDR
The spectral sen sitivity of the retina has been measured by finding the energy required at various wave-lengths through the visible spectrum to match the brightness of a fixed comparison field and the usual Purkinje shift was observed, suggesting that the rods may continue to function over a greater range of intensities than is generally accepted.

TLDR
The paper describes how contact was made with a number of tritanopes through an article published in Picture Post, and the results support the theory that tritanopia is due to the absence of blue receptors, although the location on the chromaticity chart of the fundamental stimulus associated with the blue process has not yet been determined with precision.
The characteristics of protanomalous vision
The colour vision of 11 protanomalous observers, selected from about 2,000 persons, has been tested in detail. The measurements include the luminosity curve, the mixture curves, the trichromatic
Chromaticity Sensibility to Wave-Length Difference as a Function of Purity*
Using apparatus designed by Priest and Gibson, the writer has determined sensibility to wave-length difference for his right eye: (1) For stimuli of unit purity (spectral light) from 450 to 645 mμ.
Hue-discrimination in normal colour-vision
Hue-discrimination curves have been obtained for five normal observers; the apparatus and method of observation are described and the results discussed. Two minima in the discrimination curve are
A colorimetric equipment for research on vision
Two spectra are formed by means of a dispersing system and dividing mirror. From one spectrum, two strips are reflected back through the dispersing system into a photometer prism to act as the
A re-determination of the mixture curves of the spectrum
The paper describes a method that has been developed for calculating the sensation curves and mixtures curves from an average set of trichromatic coefficients and the standard luminosity curve,
Anomalous trichromatism and its relation to normal trichromatism
The characteristics of six deuteranomalous observers and one protanomalous observer have been examined. In the case of the former it has been shown that, in contrast with what occurs in normal
