§ 1. Meanings of the word "tone:"—First, the right relation of objects in shadow to the principal light. 140 § 2.

The pictures of the old masters perfect in relation of middle tints to light. 141 § 5. And consequently totally false in relation of middle tints to darkness. 141 § 6.

And with the "Datur Hora Quieti." 145 § 11. The second sense of the word "tone." 146 § 12. Remarkable difference in this respect between the paintings and drawings of Turner. 146 § 13. Not owing to want of power over the material. 146 § 14. The two distinct qualities of light to be considered. 147 § 15.
