A correct speaker does not make a movement of limb, or feature, for which he has not a reason. If he addresses heaven, he looks upward. If he speaks to his fellow-creatures, he looks round upon them. The spirit of what he says, or is said to him, appears in his look. If he expresses amazement, or would excite it, he lifts up his hands and eyes. If he invites to virtue and happiness, he spreads his arms, and looks benevolence. If he threatens the vengeance of heaven against vice, he bends his eyebrow into wrath, and menaces with his arm and countenance. He does not needlessly saw the air with his arm, nor stab himself with his finger. He does not clap his right hand upon his breast, unless he has occasion to speak of himself, or to introduce conscience, or somewhat sentimental. He does not start back, unless he wants to express horror or aversion. He does not come forward, but when he has occasion to solicit. He does not raise his voice, but to express somewhat peculiarly emphatical. He does not lower it, but to contrast the raising of it. His eyes, by turns, according the humour of the matter he has to express, sparkle fury; brighten into joy; glance disdain; melt into grief; frown disgust and hatred; languish into love; or glare distraction.
