One has not as careful a record as one has of the works of witches, for but few English wizards came before the court, the only society for psychical research in those days. The translation, however, of Cornelius Agrippa's _De Occulta Philosophia_ in the seventeenth century, with the addition of a spurious fourth book full of conjurations, seems to have filled England and Ireland with whole or half wizards. In 1703, the Reverend Arthur Bedford of Bristol who is quoted by Sibley in his big book on astrology wrote to the Bishop of Gloucester telling how a certain Thomas Perks had been to consult him. Thomas Perks lived with his father, a gunsmith, and devoted his leisure to mathematics, astronomy, and the discovery of perpetual motion. One day he asked the clergyman if it was wrong to commune with spirits, and said that he himself held that "there was an innocent society with them which a man might use, if he made no compacts with them, did no harm by their means, and were not curious in prying into hidden things, and he himself had discoursed with them and heard them sing to his great satisfaction." He then told how it was his custom to go to a crossway with lantern and candle consecrated for the purpose, according to the directions in a book he had, and having also consecrated chalk for making a circle. The spirits appeared to him "in the likeness of little maidens about a foot and a half high ... they spoke with a very shrill voice like an ancient woman" and when he begged them to sing, "they went to some distance behind a bush from whence he could hear a perfect concert of such exquisite music as he never before heard; and in the upper part he heard something very harsh and shrill like a reed but as it was managed did give a particular grace to the rest." The Reverend Arthur Bedford refused an introduction to the spirits for himself and a friend and warned him very solemnly. Having some doubt of his sanity, he set him a difficult mathematical problem, but finding that he worked it easily, concluded him sane. A quarter of a year later, the young man came again, but showed by his face and his eyes that he was very ill and lamented that he had not followed the clergyman's advice for his conjurations would bring him to his death. He had decided to get a familiar and had read in his magical book what he should do. He was to make a book of virgin parchment, consecrate it, and bring it to the cross-road, and having called up his spirits, ask the first of them for its name and write that name on the first page of the book and then question another and write that name on the second page and so on till he had enough familiars. He had got the first name easily enough and it was in Hebrew, but after that they came in fearful shapes, lions and bears and the like, or hurled at him balls of fire. He had to stay there among those terrifying visions till the dawn broke and would not be the better of it till he died.
