Homoeopathic

"If Burd Ellen had gone “widishins" round the church, she would, I think, have used the best homoeopathic specific against the Elf-King's power; for "to go widishins" was the chief element in elfin practices, and if mortals wished to resist or unspell elf-craft, they, too, had "to go widershins," or they had to repeat the Paternoster backwards, which came to the same thing, or do something else contrariwise."
