What are these,
	So wither’d and so wild in their attire;
	That look not like the inhabitants o’ the earth,
	And yet are on’t.

Shakespeare.    

	Midnight hags,
	By force of potent spells, of bloody characters,
	And conjurations, horrible to hear,
	Call fiends and spectres from the yawning deep,
	And set the ministers of hell at work.

Rowe.
