Opinions originally entertained in this country relative to the dwarfs have undergone considerable modifications, from the same attributes being assigned to them as to the Persian peris. Fairies were supposed to have brought many blessings to England, sending people pleasant dreams, giving money to them in a mysterious manner, and causing the nation to prosper. In remote times a brownie was attached to the home of every considerable family in Ireland and the Highlands of Scotland. Like men, some brownies were tall, and some of small stature. They were industrious and faithful, if well treated in the way the Samogitæ did the Putseet. When a brownie once united himself to a family, he seldom deserted it, but continued to serve generation after generation. Burton speaks of nine classes of evil spirits:--First, the false gods of the Gentiles, adored as idols, who gave oracles at Delphos and elsewhere, whose prince was Beelzebub; second, the liars and equivocators, as Apollo, Pythias, and the like; third, the inventors of mischief, as Theutus, in Plato; fourth, malicious, revengeful devils, whose prince was Asmodeus; fifth, coseners, such as belong to magicians and witches, their prince being Satan; sixth, aërial spirits, that corrupted the air, and caused plagues, thunder, fires, and other calamities; seventh, a destroyer, causing wars, tumults, and combustions; eighth, an accusing or calumniating devil, that drove people to despair; and the ninth, tempters in divers shapes, having mammon for their prince. Burton goes further. He asserts that "no place is void, but all full of spirits, devils, or other inhabitants; not so much as a hairbreadth is empty in heaven, earth, or waters above or under the earth. The earth is not so full of flies in summer as it is at all times of invisible devils."
