From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
To Extirpate Corns.
Commence by softening the corn in a foot-bath, then cut the corn as close as possible. In case of a man, wait for the funeral of a man; in case of a woman, wait for the funeral of a female; be seated in your bed-room, take off the stocking and move the index finger over the corn, and speak thus: What I touch may vanish, what I hold may depart like the dead in the tomb, in the name of God the Father, the Son and Holy Spirit. As long as the bells are tolling speak the above formula, and continue to move over the corn, and say constantly as follows: And "what I touch may vanish like the dead in the grave," three times, but always pronounce the three highest names.
