""Equity is a roguish thing : for law we have a measure ; know what to trust to. Equity is according to the conscience of him that is Chancellor; and, as that is larger or narrower, so is equity. 'Tis all one, as if they should make his foot the standard for the measure we call a foot 'a Chancellor's foot'; what an uncertain measure would this be! One Chancellor has a long foot. another a short foot, a third an indifferent foot; 'tis the same thing in the Chancellor's conscience."
