But the difficulty may be eluded.

I have already gone to literature for examples of special feelings on the part of individuals, and under certain circumstances.
We will now go to it for a kindred, though not for the same assistance; and for this end we shall approach it in a slightly different way.

What we did before was this.

We took certain works of literary art, and selecting, as it were, one or two special patches of colour, we analysed the composition of these.

What we shall now do will be to take the pictures as organic wholes, with a view to analysing the effect of them as pictures--the harmony or the contrast of their colours, and the massing of their lights and shadows.
