Old Miss Croker, of Ross House, who was near seventy in the year 1821, when she related this story to me, had seen and conversed with Alice De Lacy, a professed nun, under the name of Sister Agnes, in a religious house in King-street, in Dublin, founded by the famous Duchess of Tyrconnell, and had the narrative from her own lips.  I thought the tale worth preserving, and have no more to say.
