Note CXLII — THE CHASE OF SLIEVE CULLINN.
P. W. (Patrick Weston) Joyce translation
] The little lake for which this legendary origin is assigned lies near the top of Slieve Gullion. There were several wells in Ireland which, according to the belief of old times, had the property of turning the hair grey. Giraldus Cambrensis tells us of such a well in Munster; and he states that he once saw a man who had washed a part of his head in this well, and that the part washed was white, while the rest was black!
It is to be observed that the peasantry of the district retain to this day a lingering belief in the power of the lake of Slieve Gullion to turn the hair grey.
