The following extraordinary circumstance, which occurred to a young lady whilst on a visit at the house of an English nobleman of the highest rank, is, I believe, unparalleled for acute mental anguish and excitement, during the hours of its continuance. It was related to us by the descendant of a person who resided in the Hall during its occurrence, and I have every reason to believe it to be substantially true, in all its main features. In order to make it more intelligible, and give it that effect to which it seems well entitled, a short description of the place may perhaps be allowed. Haddon Hall, in the county of Derby, is situated in the upper or mountainous part of the county, called, from that circumstance, the High Peak. The manor of Haddon, at the time of the Norman invasion, in the year 1066, was given by the conqueror to William Peverel, his natural son, whose descendants were named Avenel, and in them it remained till towards the close of the twelfth century, when it changed possessors by the union of Avicia Avenel with Sir Richard de Vernon, whose heirs held it for three centuries, at which time it became the properly of the noble family who now retain it, by the marriage of Dorothy, daughter of Sir George Vernon, with Sir John Manners, second son of the Earl of Rutland, in 1565, very nearly three hundred years ago. Sir George Vernon had the proud title of King of the Peak conferred upon him by courtesy, in consequence of his splendid hospitality, and immense number of servants and retainers, during the reign of King Henry the Eighth.
