WHICH THREE GHOST DO THE WITCHES SHOW MACBETH, AND WHAT DOES EACH APPARITION SUGGEST ABOUT MACBETH'S FUTURE?

The first is an armed head that warns Macbeth to beware the Thane of Fife (Macduff). The second apparition is a bloody child, who tells him that "none of woman born / Shall harm Macbeth" (96-97).
