Nor do the pains she is at to "screw his courage to the sticking-place," the reproach to him, not to be "lost so poorly in himself," the assurance that "a little water clears them of this deed," shew anything but her greater consistency in depravity. Her strong-nerved ambition furnishes ribs of steel to "the sides of his intent;" and she is herself wound up to the execution of her baneful project with the same unshrinking fortitude in crime, that in other circumstances she would probably have shewn patience in suffering. The deliberate sacrifice of all other considerations to the gaining "for their future days and nights sole sovereign sway and masterdom," by the murder of Duncan, is gorgeously expressed in her invocation on hearing of "his fatal entrance under her battlements:"-- ----"Come all you spirits That tend on mortal thoughts, unsex me here: And fill me, from the crown to th' toe, top-full Of direst cruelty; make thick my blood, Stop up the access and passage to remorse, That no compunctious visitings of nature Shake my fell purpose, nor keep peace between The effect and it. Come to my woman's breasts, And take my milk for gall, you murthering ministers, Wherever in your sightless substances You wait on nature's mischief. Come, thick night! And pall thee in the dunnest smoke of hell, That my keen knife see not the wound it makes, Nor heav'n peep through the blanket of the dark, To cry, hold, hold!"---- When she first hears that "Duncan comes there to sleep" she is so overcome by the news, which is beyond her utmost expectations, that she answers the messenger, "Thou'rt mad to say it:" and on receiving her husband's account of the predictions of the Witches, conscious of his instability of purpose, and that her presence is necessary to goad him on to the consummation of his promised greatness, she exclaims-- ----"Hie thee hither, That I may pour my spirits in thine ear, And chastise with the valour of my tongue All that impedes thee from the golden round, Which fate and metaphysical aid doth seem To have thee crowned withal."
