Abstract
THE nature of the volume can be indicated by stating one of the propositions of the author's theory of colour: “That exhausted viable matter absorbs the luminous rays, and reflects the invisible (potential) rays, therefore it is dark or nearly colourless, sometimes violet or purple being perceptible; and that viable matter stored with energy reflects the luminous rays, therefore it is yellow or some colour containing excess of yellow, as brown, or cream colour, &c., and absorbs the invisible or potential rays.”
