Baxter in his _Certainty of the World of Spirits_ quotes what at first sight appears to be the same case, but places it at Utrecht, and dates it 1625. But it is quite possible for a similar incident to have occurred on the Continent as well as in Ireland; many cases of witchcraft happening at widely different places and dates have points of close resemblance. Sinclair's story appears to be based on an actual trial for witchcraft in co. Antrim, the more so as he has drawn his information from a pamphlet on the subject which was printed the year after its occurrence. The mention of this latter is particularly interesting; it was probably locally printed, but there appears to be no means of tracing it, and indeed it must have been thumbed out of existence many years ago. The above story, marvellous though it may seem, is capable of explanation. The oxalic acid in sorrel is an irritant poison, causing retching and violent pains. But when once the suspicion of _witchcraft_ arose the ejection of such an extraordinary collection of miscellaneous articles followed quite as a matter of course--it would, so to speak, have been altogether against the rules of the game for the girl to have got rid of anything else at that particular date.
Classon Porter gives what he considers to be the traditional version of the above. According to it the supposed witch was a poor old woman, who was driven mad by the cruel and barbarous treatment which she received from many of her neighbours on the ground of her being a witch. To escape this treatment she sought refuge in a cave, which was in a field attached to the old (not the present) meeting-house in Antrim. Her living in such a place being thought a confirmation of what was alleged against her, she was thereupon stabbed to death, and her body cut in pieces, which were then scattered over the places where she was supposed to have exercised her evil influence. For some years after this terrible tragedy her ghost, in the form of a goat, was believed to haunt the session-house of the old meeting-house near which she had met her cruel fate; it was popularly known as MacGregor's ghost, this having been the name of the man who was sexton of the meeting-house when these things took place, and who probably had been concerned in the murder. So far Classon Porter. But we very much doubt if the above has really any connection with the Antrim witch-case of 1698. It seems more probable that it occurred at a later date, possibly after the Island-Magee trial, and thus would be an instance of one of those outbursts of cruelty on the part of a mob rendered ferocious by ignorance and superstition, of which examples are to be found in England during the eighteenth and nineteenth centuries.
