I have read in some eighteenth-century book whose name I cannot recall of two men who made a magic circle and who invoked the spirits of the moon and saw them trampling about the circle as great bulls, or rolling about it as flocks of wool. One of Lady Gregory's story-tellers considered a flock of wool one of the worst shapes that a spirit could take. There must have been many like experimenters in Ireland. An Irish alchemist called Butler was supposed to have made successful transmutations in London early in the eighteenth century, and in the _Life of Dr. Adam Clarke_, published in 1833, are several letters from a Dublin maker of stained glass describing a transmutation and a conjuration into a tumbler of water of large lizards. The alchemist was an unknown man who had called to see him and claimed to do all by the help of the devil "who was the friend of all ingenious gentlemen." W. B. Y. 1914. FOOTNOTE: [1] I have modernized the old lowland Scotch in these quotations from _Pitcairn's Criminal Trials_. NOTES NOTES NOTE 1. THE FAERY PEOPLE. The first detailed account of the Faery People of the Gaelic race was made by the Reverend Robert Kirk in 1691. His book which remained in manuscript till it was discovered by Sir Walter Scott in 1815 was called _The Secret Commonwealth_, an essay "of the nature of the subterranean (and for the most part invisible people) heretofore going under the names of elves, fays, and faeries." Kirk was a Gaelic scholar, a translator into Gaelic of the Psalms. He is described upon his tomb as _Lignæ hibernæ lumen_, for in his day little distinction was made between the Irish and the Scottish-Irish among whom he lived and whose words he has recorded. He died a year after he had finished his manuscript or, as the people of his parish say, was taken by the faeries. The Reverend William Taylor, the present incumbent of Abberfoyle, Kirk's old living, told Mr. Wentz that it was generally believed at the time of Kirk's death, that the faeries had carried him off because he had looked too deeply into their secrets. He seems to have fainted while walking upon a faery knoll, a little way from his own door, and to have died immediately. Mr. Wentz found one old Gaelic speaker who believed that his spirit had been taken, but others who said there was nothing in the grave but a coffin full of stones, for body and soul had been taken. Mr. Lang prints a tradition that Kirk appeared to his cousin Graham of Ducray and could have been saved if the cousin had dared to throw a knife over the apparition's head.
