Still more widely diffused is the practice of infanticide as the sequence of superstition. The belief that dwarfs or gnomes, dwelling in the inner parts of the earth, carry off beautiful newborn babes and leave their own deformed offspring in their stead is not confined to any one people, but is current alike in Germanic, Celtic, Romanic, and Slavic countries, and causes a misshapen child to be looked upon with suspicion and subjected to cruel tortures and even killed. The supposed changeling is often severely beaten with juniper rods and the scourging attended with incantations, so as to compel the wicked fairies to reclaim their deformed bantling and restore the stolen child. If the castigation proves ineffective, more summary measures are frequently taken, and the supposititious suckling is thrown out of the window on a dunghill or immersed in boiling water. In 1877, in the city of New York, an Irish immigrant and his wife burned their child to death under the delusion that they were ridding themselves of a changeling. Cases of this kind are quite common in Ireland, where the victims are sometimes adults.[28] Not long since Magoney, an Irish peasant, had a sickly child, which the most careful nurture failed to restore to health and strength. The parents, therefore, became convinced that a changeling had been imposed upon them, and when the boy was four years old they resolved to have recourse to boiling water, in which he was kept, notwithstanding his shrieks and protestations that he was not an elf, but their own Johnny Magoney, until death released him from his torments.
Wilhelm Mannhardt, the celebrated writer on folklore, states that when, in 1850, he was in Löblau, a village of West Prussia, he saw a man brutally maltreating a boy on the street. On inquiry he found that the lad had done nothing worthy of blame, but that his only fault was an exceptionally large head. This cranial peculiarity, offensively conspicuous in what seems to have been a narrow-headed family, was reason enough for the parents to disown their offspring, and to treat him as the counterfeit of a child foisted in by the fairies. At Hadersleben, a considerable market town of North Silesia, the wife of a farmer, in 1883, gave birth to a puny infant, which the parents at once assumed to be a changeling. In order to defeat the evil designs of the elves and to compel the restoration of their own child, they held the newborn over a bed of live coals on the hearth until it was covered with blisters and died in intense agony. In East Prussia, the Mazurs, a Polish race, whose only notable contribution to modern civilization and the gayety of nations is the mazurka, take precautionary measures by placing a book (usually the Bible, although any book will do) under the head of the newborn babe, so as to prevent the devil from spiriting it away and substituting for it one of his own hellish brood, thus unwittingly furnishing a marvelous illustration of the beneficent influence of the printing press and the magic power of literature. The Estonian inhabitants of the island of Oesel in Livonia refrain from kindling a fire in the house while the rite of baptism is being celebrated, lest the light of the flames should render it easier for Satan surreptitiously to exchange an imp for the infant. After the sacred ceremony has been performed there is supposed to be no danger of such a substitution.
