Such is the similarity of the various Scottish witch-trials that too-detailed recapitulation would be tedious and unprofitable. Some, however, stand out from the rest by reason of their grotesque horror and exaggeration. Such is the trial of Isobel Grierson, "spous to Johnne Bull, wark-man in the Pannis" (Preston Pans), tried at Edinburgh in March, 1607. Grierson, by the way, was a name very prominent in witch-circles at the time. One Robert Grierson had taken a leading part as an accomplice of Dr. Fian, above referred to, his being the hand which cast the enchanted cat into the sea in the endeavour to drown King James. He was also, as shown in the confession of another defendant in the same trial, the cause of much disturbance at a Sabbath held in North Berwick Churchyard. Satan, by an unfortunate slip, addressed him by his real name. As etiquette strictly demanded that Christian names should be ignored, and nicknames--in this instance "Rab the Rower"--used instead, the mistake appeared an intentional insult on Satan's part, and was so taken by the assembled witches, who expressed their displeasure with uncompromising vigour, even to the extent of running "hirdy girdy" about the churchyard. But to return to John Bull's wife. She was accused, _inter alia_, of having conceived a cruel hatred and malice against one Adam Clark, and with having for the space of a year used all devilish and unholy means to be revenged upon him. On a November night in 1606, between eleven and midnight, Adam and his wife being in bed, Isobel entered the house in the form of a black cat, accompanied by a number of other cats, and made a great and fearful noise, whereat Adam, his wife, and maid-servant were so frightened as almost to go mad. Immediately afterwards the Devil appeared, in the likeness of a black man, seized the servant's nightcap and cast it on the fire, and then dragged her up and down the house. Who thereby contracted a great sickness, so that she lay bed-fast, in danger of her life, for the space of six weeks. Isobel was further accused of having compassed the death of William Burnet and of laying on him a fearful and uncouth sickness, by casting in at his door a gobbet of raw, enchanted flesh. Whereafter the Devil nightly appeared in poor William's house in the guise of a naked infant child for the space of half a year. Occasionally he varied the performance by appearing in the shape of Isobel herself, but being called by her name would immediately vanish away. As a result of all which, Adam languished in sickness for the space of three years, unable to obtain a cure, and at last, in great "douleur and payne," departed this life. Another of her victims was Robert Peddan, who remained sick for the space of one year and six months, and then suddenly remembering that he owed Isobel nine shilling and fourpence, and that before the time of his sickness, as he had refused to pay it, she had delivered to him certain writings that
