From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
To Beat Witches.
Let the sweepings, which are swept together in a house for three days remain in a heap, and on the third day cover it with a black cloth made of drilling, then take a stick of an elm tree and flog the dirt heap bravely, and the sorceress must assist, or you will batter her to death. Probatum.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
