27 PLATE III. The two upper leaves are lylac leaves, shewing the upper sides: in these leaves, four tints are shewn; in smaller leaves it would be more difficult to put so many tints: therefore, I thought it proper to give these large leaves, on purpose to introduce a greater number of tints, and shew the method of higher finishing. The first tint is laid in with sap green, worked thin. The second is sap green, a little stronger. The third a little stronger still. And the fourth is by adding a little Prussian blue, and more sap green. The veins are cut up with this last tint. The two under leaves are rose leaves, and given for the same purpose as the above, because there are four tints in these; but their representing the under sides of the leaves, gives an opportunity of shewing the effect of four tints in a different coloured leaf. The first tint is laid in with No. 2, of the greens; the second is with adding a very little more yellow and blue; the third, by strengthening the last a little more; and the fourth is with adding a little more blue, and a little yellow oker. With this last tint you may cut up the veins. When you come to be more perfect in colouring, you will find it very easy to work up a leaf so high, as to make use of seven or eight tints, or more.
