And as the amateur increases in power, and
enlarges his drawings, the touch may be gradually
rendered more and more discriminative, until the
appearance of every leaf on a tree, and every hair
on a dog's back, may be rendered distinct (Plate
XXIV. fig. 4). Examples of which may be
found in numerous drawing books and studies,
published by various artists.

A few examples of the principal varieties of the
