A person simply directs his eyes to see.  He looks.  But eyes may speak, we are told, and since this person undergoes many changes of mood and purpose, we shall let his eyes tell us all they will about his different manners of looking.  At first he but looks momentarily (as from lack of time) or casually (as from lack of interest).  He glances.  Soon he makes a business of looking, and fastens his eyes for a long time on something he admires or wonders at.  He gazes.  Presently he looks with a blank, perhaps a rude, expression and with eyes opened widely; he may be for the moment overcome with incomprehension, surprise, or fright, or perhaps he wishes to be insolent.  He stares.  Now he is looking narrowly or closely at something that he sees with difficulty.  He peers.  The next moment he looks over something with care or with an encompassing sweep of vision.  He scans it.  His interest thoroughly enlisted, he looks at it carefully point by point to see that it is right in each detail.  He scrutinizes it.  He then alters his mood, and looks with scornful or malignant satisfaction upon something he has conquered or has power over.  He gloats.  Anger, perhaps fierceness, takes possession of him, and he looks with piercing eyes.  He glares.  Threat mingles with anger, and in all likelihood he looks scowlingly or frowningly.  He glowers.  An added expression of sullenness or gloom comes into his look.  He lowers.  He throws off his dark spirit and looks slyly and playfully, let us say through a small opening.  He peeks.  Playfulness gives place to curiosity; he looks quickly and furtively, perhaps through some tiny aperture, and probably at something he has no business to see.  He peeps.  The while he looks his mouth falls open, as from stupidity or wonder.  He gapes.  He looks at something a long time to study it.  He cons or pores.  His study is not of the thing itself; it is meditation or reverie.  He pores.  A member of the opposite sex is present; he looks at her with the effort of a flirt to attract attention to himself, or less scrupulous, he directs toward her amorous or inviting glances.  He ogles.
