The daughter of a farmer in the neighbourhood was ill with jaundice. The doctor of the parish was attending her, but she was becoming worse instead of better, and her end seemed near. Her distressed parents sent for 'Aonas nan gisrean,' Angus of the exorcisms, and he came. The man examined the girl and announced that she was possessed of the demon of the jaundice, but that he would expel the demon and cure the girl. He requested the mother to put on a big fire, the sisters to bring a tub of clear cold water, and the father to bring the plough irons, evil spirits being unable to withstand iron. All this was promptly done. The exorcist placed the plough irons in the fire, displaying much solicitude that they should be red-hot. The room was darkened and the eyes of the patient were bandaged that the eyes of the body might be subjective to the eyes of the mind. Directed by the exorcist, the mother and sisters placed the back of the girl to the front of the bed, and laying it bare left the room, the man securing the door after them. Making a clanging noise with the plough irons as if to drive away the jaundice demon, the man replaced the share in the fire and put the coulter in the water. Then pretending to take the red-hot share out of the fire, he took up the icy-cold coulter and placed it along the spine of the p. 13 patient, loudly commanding the demon to depart. The girl screamed in evident agony, calling on the Mother of Christ and on the Foster-mother of Christ, and on her own mother, to come and rescue her from the brutal treatment of black Angus the father of evil, the brother of demons, and to see how her blood was flowing in streams and her flesh was burnt off her back, laying her backbone bare. While loudly calling to the jaundice demon to depart, the expert exorcist threw the red-hot share into the tub of water, adding to the already abundant noise in the room. Against the remonstrances of the father, who said that Angus knew what he was about, the mother and sisters burst open the door, calling on Mary Mother to rescue the maltreated girl, and on Calumcille to redress her wrongs.

'Whether the cure was due to her simple faith in the exorcist or to the shock to her nervous system I do not know,' continued the narrator, 'but in a few days the girl was up and about. She is grateful, but shy of me ever since, probably remembering the hard things she said. She will always believe that I exercised some occult power over the jaundice demon. The case of this girl was as bad as any I have seen. She had been an attractive, comely girl, with a winning expression and a clear complexion, but she had become yellow-black instead of rosy-red.'
