Thou canst not say I did it; never shake

Thy gory locks at me.

Macbeth. Act iii. Sc. 4.

The air-drawn dagger.

Macbeth. Act iii. Sc. 4.

The time has been,

That when the brains were out the man would die,

And there an end; but now they rise again,

With twenty mortal murders on their crowns,

And push us from our stools.
