Chap. XVI.—The Manner of drawing from Relievos, and rendering Paper fit for it.
When you draw from relievos, tinge your paper of some darkish demi-tint. And after you have made your outline, put in the darkest shadows, and, last of all, the principal lights, but sparingly, especially the smaller ones; because those are easily lost to the eye at a very moderate distance[5].
Chap. XVII.—Of drawing from Casts or Nature.
In drawing from relievo, the draftsman must place himself in such a manner, as that the eye of the figure to be drawn be level with his own[6].
Chap. XVIII.—To draw Figures from Nature.
Accustom yourself to hold a plummet in your hand, that you may judge of the bearing of the parts.
Chap. XIX.—Of drawing from Nature.
When you draw from Nature, you must be at the distance of three times the height of the object; and when you begin to draw, form in your own mind a certain principal line (suppose a perpendicular); observe well the bearing of the parts towards that line; whether they intersect, are parallel to it, or oblique.
