Abstract
THE article in NATURE of May 14 on the exhibition of the Royal Academy reminds me of a discussion I once had with a brother of Sir Charles Walston, who was a medical man interested in art. He was looking out for a method to determine the average colour of a picture, which he thought was characteristic of the painter, and might serve to identify him as certainly as finger-prints identify persons. I could only refer him to the method tried by the third Lord Rayleigh, when instead of spinning colour discs he looked at the stationary discs after reflexion from a surface that could be set into rotation. Applied to a painting, this would then give the average colour for concentric circles round the centre of rotation.
