Read the excerpt from act 3, scene 4 of The Tragedy of Macbeth.Macbeth. Then comes my fit again: I had else been perfect;Whole as the marble, founded as the rock,As broad and general as the casing air:But now I am cabin’d, cribb’d, confin’d, bound inTo saucy doubts and fears. But Banquo ’s safe?First Murderer. Ay, my good lord; safe in a ditch he bides,With twenty trenched gashes on his head;The least a death to nature.Macbeth. Thanks for that.There the grown serpent lies: the worm that’s fledHath nature that in time will venom breed,No teeth for the present. Get thee gone; to-morrowWe’ll hear ourselves again.
