LETTER X.
As you are by this time able to make correct drawings of the separate parts of
the human figure, we will proceed to subjects in which they are united.
Plate LXIV. is an outline and finished drawing of the lower part of the face seen
in profile. The outline must be studied first, and every part formed correctly, observ-

put in strong shade. This is done in the outline before us in the touch under the
nose, the lower part of the upper lip, and the corner of the mouth. This variation
in the strength of the line, according to its situation, often renders free outline draw-

make a good drawing, if the outline is not perfect. You may now proceed to put
the sketch in the first shade, by covering all parts of the drawing, except that
which is left in strong lights, with curved lines; cross these lines for the darker or
second shade, taking care to hold the pencil or portcrayon as far as possible from
