Come, you spirits That tend on mortal thoughts, unsex me here, And fill me from the crown to the 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 murd'ring ministers, Wherever in your sightless substances You wait on nature’s mischief.
