The mode of summoning and of exorcising familiar spirits--in other words, of laying and raising the devil--varies little the world over. Even in China, the magic circle is entered and incantations are muttered when the fiend is summoned; and for the exorcism of devils there are laws like our own--though since modern Christianity has been introduced in China the most popular exorcist is the Christian missionary.[85] In Wales, the popular belief is compounded of about equal parts of foul magic and fair Biblical text; magic chiefly for summoning, the Book for exorcising.
