In the island of Lewis, one of the Hebrides, are the ruins of a chapel formerly dedicated to St. Mulvay, near which is a spring, the water of which was supposed to be of singular efficacy in curing diseases of the brain. The patient was made to walk seven times round the ruins, and was then sprinkled with water from the spring. In others of the Hebrides, and along the west coast, there are many wells named after St. Columba. Almost every well in Scotland is, indeed, named after some mediaeval saint, many of them of only local fame, and very few having a place in the ecclesiastical kalendar. St. Ronan's Well, from the association with it of Scott's novel of that name, is the best known to the general reader. It has been identified with the mineral well at Innerleithen, in the county of Peebles, which long enjoyed good repute as a curative agent in diseases of the eye and the skin, and also in dyspepsia. The church of St. Fergus, in Buchan, commemorates an Irish missionary of the eighth century, in whose memory a well in the parish of Kirkmichael, in Banffshire, is named. Concerning this spring, Dr Gregor, in his "Folk Lore of the North-east of Scotland," says:--"Easter Sunday and the first Sunday in May were the principal Sundays for visiting it, and many from the surrounding parishes, who were affected with skin diseases or running sores, came to drink of its water, and to wash in it. The hour of arrival was twelve o'clock at night, and the drinking of the water and the washing of the diseased part took place before or at sunrise. A quantity of the water was carried home for future use. Pilgrimages were made up to the end of September, by which time the healing virtues of the water had become less. Such after-visits seem to have begun in later times." The best known of several wells named after St. Helena, the mother of Constantine, is beside the road from Maybole to Ayr, and about two miles and a half from the former place. It used formerly to be much resorted to on the 1st of May, for the benefit of sickly children. St. Iten's Well, at Cambusnethan, in Lanarkshire, at one time was held in good repute as a cure for asthma and skin diseases. Martin, in a description of the Hebrides, written about 1695, mentions a well named after the same saint in the Isle of Eigg, which was regarded by the natives as a panacea for "all the ills that flesh is heir to." He gives a curious, and in view of the connection of holy wells with pagan beliefs and customs, an interesting account of the dedication of this well by a priest called Father Hugh.
