istic of Lady Macbeth that put her in alignment with the witches is that she offers to nurse the spirits from her own breasts. "Witches nursed their familiars from their 'marks,' considered as teats of diabolic nourishment" (Wills 80). When Lady Macbeth says, "Come to my woman's breasts / And take my milk for gall" (1.5.47-48), she was telling her familiars " . . . to take her milk as gall to nurse from her breast and find in her milk their sustaining poison" (Adelman 112).

When Macbeth tries to get out of his agreement with Lady Macbeth, she challenges his courage and strength as a man when she says,I have given suck, and know How tender 'tis to love the babe that milks me;I would, while it was smiling in my face,Have plucked my nipple from his boneless gumsAnd dashed the brains out, had I so sworn as youHave d...
