e retina produce certain effects which convey to our consciousness the sensation of red, and we say "That is a red object." But there may be particles of moisture or dust in the air that will modify the red rays so that by the time they reach the eye they may be somewhat different. This modification is naturally most e

focus for the time being. In a picture the eyes can only focus at one distance (the distance the eye is from the plane of the picture when you are looking at it), and this is one of the chief causes of the perennial difficulty in painting backgrounds. In na

t planes, would not suffice to account for our knowledge of the solidity and shape of the objective worl

of what is and what is not within its reach. Who has not offered some bright object to a young child and watched its clumsy attempts to feel for it, almost as clumsy at first as if it were blind, as it has not yet learned to focus distances. And when he has at last got hold of it, how eagerly he feels it all over, loo

Or take two painters both equally gifted in the power of expressing their visual perceptions, and put them before the scene to paint it.

The mouth similarly is an opening with a row of teeth, which are generally shown although so seldom seen, but always apparent if the mouth is felt (see diagram A). This is, I think, a fair type of the first drawing the ordinary child makes-and judging by some ancient scribbling of the same order I remember noticing scratched on a wall at Pompeii, and by savage drawing generally, it appears to be a fairly universal type. It is a very remarkable thing which, as far as I know, has not yet been pointed out, that in these first attempts at drawing the vision should not be consulted. A blind man would not draw differently, could he but see to draw. Were vision the first sense consulted, and were the simplest visual appearance sought after, one might expect something like diag

If one looks up at a fine mass of cumulus clouds above a London street, the ordinary passer-by who follows one's gaze expects to see a balloon or a flying-machine at least, and when he sees it is only clouds he is apt to wonder what one is gazing at. The beautiful form and colour of the cloud seem to be unobserved. Clouds mean nothing

Everybody does not need to draw and paint, but if everybody could get the faculty of appreciating the form and colour on their retinas as form and colour, what a wealth would always be at their disposal for enjoyment! The Japanese habit of looking at a landscape upside down between their legs is

r sense of touch associated with vision, whose primitive instinct is to put an outline round objects as representing their boundaries in space. And secondly, there is the visual perception, which is concerned with the visual aspe

nected. You cannot put an accurate outline round an object without observing the shape it occupies in the field of vision. And it is difficult to consider the "mosaic of colour forms" without being very conscious of the objective significance of the colour masses portrayed. But they present two entirely different and opposite points of view from which the representation of objects can be approached. In considering the subject of drawing I think it necessary to make this division of the subject, and both methods of form expressio
