She was then attacked, however, by some internal disease; and after many months of suffering, she was reduced into that abnormal and singular condition, in which she exhibited the phenomena known to modern wonder-seekers as those of somnambulism or clairvoyance.

In the histories of all countries and of all times, we are familial with accounts of young women of bad health and irritable nerves, who have exhibited at recurring periods certain unusual powers; and these exhibitions have had especial attraction for superstitious persons, whether they have believed in God, or in the devil, or in neither. A further feature also uniform in such cases, has been that a small element of truth may furnish a substructure for a considerable edifice of falsehood; human credulity being always an insatiable faculty, and its powers being unlimited when once the path of ordinary experience has been transcended.
