         In value the satisfaction I had in seeing it
         represented with all the justness and gracefulness of
         action.                                  --Dryden.

   Note: Justness is properly applied to things, and justice to
         persons; but the distinction is not always observed.

        reasonableness; equity; uprightness; justice.
