From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
When a person is troubled with a tumor or desires to remove Corns.
When they bury an old man, and the funeral bells are ringing, the following should be spoken: they are sounding the funeral bell and what I now grasp may soon be well and what ill I grasp do take away, like the dead one in the grave does lay. + + + Whilst reciting the sentence, always hold the troubled part in the hand, and regarding the corns, move over them with your fingers after cutting out the corns, and as long as they are tolling the bells repeat the above. As soon as the dead body begins to bleach the tumor or the corns will disappear. Probate in the case of a male, wait for the funeral of one of that sex; in the case of a female wait until a female is to be buried.
