Like the poore Cat i'th' Addage

Macb. Prythee peace:
I dare do all that may become a man,
Who dares do more, is none

La. What Beast was't then
That made you breake this enterprize to me?
When you durst do it, then you were a man:
And to be more then what you were, you would
Be so much more the man. Nor time, nor place
Did then adhere, and yet you would make both:
They haue made themselues, and that their fitnesse now
Do's vnmake you. I haue giuen Sucke, and know
How tender 'tis to loue the Babe that milkes me,
I would, while it was smyling in my Face,
Haue pluckt my Nipple from his Bonelesse Gummes,
And dasht the Braines out, had I so sworne
As you haue done to this

Macb. If we should faile?
Lady. We faile?
But screw your courage to the sticking place,
And wee'le not fayle: when Duncan is asleepe,
(Whereto the rather shall his dayes hard Iourney
Soundly inuite him) his two Chamberlaines
Will I with Wine, and Wassell, so conuince,
That Memorie, the Warder of the Braine,
Shall be a Fume, and the Receit of Reason
A Lymbeck onely: when in Swinish sleepe,
