12 PICTORIAL EFFECT.

effect of the whole be not disturbed or altered;
and the whole may be slightly modified, so that
the principle (which in this example is developed
as distinctly as possible) may not be so instan-
taneously evident. There is an engraving in the
" Keepsake" for 1831, from a beautiful picture
by Bonington, of a coast scene, in which, for the
purpose of obtaining this wedge-formed mass of
dark, a shadow is thrown upon the cliff that
could not by any possibility be there. Will the
amateur condescend to take a similar liberty with
Nature, or will he prefer to be obnoxious to

Mr. H----------n's remark to a lady,—" Oh, you

wish to be reasonable, do you?"

The principle upon which the rule is con-
structed, may be applied in reversing the light
and shadow, making the former assume the
wedge-shape, as in the example annexed (Plate
I, fig. 2). The picture known as Rembrandt's
Mill is constructed upon this application of the
principle, though darker in general tone, — the
wedge-shaped light being smaller, in comparison
with the shadow, than in the example.
