Sometimes the spirit in animal form is the spirit of a mortal, doomed to wear this shape for some offence. This again trenches on the ground of magic; but the ascription to the spirit-world is distinct in modern instances. There was a Rev. Mr. Hughes, a clergyman of the Church of England, in the isle and county of Anglesea, who was esteemed the most popular preacher thereabout in the last century, and upon this account was envied by the rest of the clergy, 'which occasioned his becoming a field preacher for a time, though he was received into the Church again.'[69] As he was going one night to preach, he came upon an artificial circle in the ground, between Amlwch village and St. Elian Church, where a spirit in the shape of a large greyhound jumped against him and threw him from his horse. This experience was repeated on a second night. The third night he went on foot, and warily; and now he saw that the spirit was chained. He drew near, but keeping beyond the reach of the chain, and questioned the spirit: 'Why troublest thou those that pass by?' The spirit replied that its unrest was due to a silver groat it had hidden under a stone when in the flesh, and which belonged to the church of St. Elian. The clergyman being told where the groat was, found it and paid it over to the church, and the chained spirit was released.
