But if the Out-Lines are only mark’d, this also is Drawing ; ‘tis giving the true Form of what is pretended to, that is, the Out-Line.
The Drawing in the latter, and most common Sense ; besides that it must be Just, must be pronounced Boldly, Clearly, and without Ambiguity : Consequently, neither the Out-Lines, nor the Forms of the Lights, and Shadows must be Confus’d, and Uncertain, or Wooly (as Painters call it) upon pretence of Softness ; nor on the other hand may they be Sharp, Hard, or Dry ; for either of these are Extreams ; Nature lies between them.

But the Handling may be such as to be not only Good abstractedly consider’d, but as being Proper, and adding a real Advantage to the Picture : And then to say a Picture has such, and such good Properties, and is also Well Handled (in that Sense) is as to say a Man is Wise, Virtuous, and the like, and is also Handsome, and perfectly Well bred.
Generally if the Character of the Picture is Greatness, Terrible, or Savage, as Battels, Robberies, Witchcrafts, Apparitions, or even the Portraits of Men of such Characters there ought to be employ’d a Rough, Bold Pencil ; and contrarily, if the Character is Grace, Beauty, Love, Innocence, &c. a Softer Pencil, and more finishing is proper.

There are two Mistakes very common ; One is because a great many good Pictures are very Rough painted People fancy that is a Good Picture that is so. There is Bold Painting, but there is also Impudent Painting. Others on the contrary judge of a Picture not by their Eyes, but by their Fingers ends, they Feel if it be good. Those appear to know little of the true Beauties of the Art, that thus fix upon the least considerable Circumstance of it as if it were All, or the Principal thing to be consider’d.
