To Carew's account Dr. Borlase adds that in his opinion "a similar bowssening pit has existed at a well in St. Agnes' parish." Among other Cornish wells which had healing virtues assigned them was St. Levan's, and the insane, no doubt, partook of them. "Over the spring," says Dr. Boase, "lies a large flat stone, wide enough to serve as a foundation for a little square chapel erected upon it; the chapel is no more than five feet square, seven feet high, the little roof of it of stone. The water is reckoned very good for eyes, toothache, and the like, and when people have washed, they are always advised to go into this chapel and sleep upon the stone, which is the floor of it, for it must be remembered that whilst you are sleeping upon these consecrated stones, the saint is sure to dispense his healing influence." Madron Well attained a great celebrity for healing diseases and for divining. "Girls dropped crooked pins in to raise bubbles and divine the period of their marriage."[21] Mr. W. C. Borlase, M.P., informs me that at St. Kea, near Truro, within the walls of the church, was a stone to which, within the memory of an old gentleman who died only about two years ago, an inhabitant of the parish, on becoming insane, was chained. He adds that just as Altarnun is Nun's altar, the parish of Elerky is derived from St. Kea's altar (Eller or Aller-kè). Scotland was still more remarkable than Cornwall for its lunacy-healing wells and extraordinary superstitions, surviving also to a much later period; in fact, not yet dispelled by civilization and science. Every one has heard of St. Fillan's Well (strictly, a pool) in Perthshire, and knows the lines in "Marmion"-- "Then to Saint Fillan's blessed well, Whose spring can frenzied dreams dispel, And the crazed brain restore." This well, derived from the river of that name in the vale of Strathfillan, and consecrated by the saint who, according to tradition, converted the inhabitants to Christianity,[22] has been ever since distinguished by his name, and esteemed of sovereign virtue in curing madness. There was an abbot living in the Vale of St. Fillan in 1703. "He is pleased," says Pennant, in his "Tour in Scotland" (vol. ii. p. 15), "to take under his protection the disordered in mind; and works wonderful cures, say his votaries, unto this day." It was, he says, a second Bethesda. He wrote in 1774.
