The lady who owned the apartments flattered herself that this apparition betokened that a treasure was hidden under the stove, and, imposing silence on the girls, she sent for a carpenter and had the planks lifted. The floor was found to be double, and below was a vault, from which issued a very unwholesome vapor, but no treasure was found, nor anything but a quantity of quicklime. The circumstance being now made known to the king, he expressed no surprise; he said that the apparition was doubtless that of a countess of Orlamunde, who had been buried alive in that vault. She was the mistress of a margrave of Brandenburg, by whom she had two sons. When the prince became a widower, she expected he would marry her; but he urged as an objection that he feared, in that case, her sons might hereafter dispute the succession with the lawful heirs. In order to remove this obstacle out of her way, she poisoned the children; and the margrave, disgusted and alarmed, had her walled up in that vault for her pains. He added that she was usually seen every seven years, and was preceded by the sound of a harp, on which instrument she had been a proficient; and also that she more frequently appeared to children than to adults,—as if the love she had denied her own offspring in life was now her torment, and that she sought a reconciliation with childhood in general.

The following very curious relation I have received from the gentleman to whom the circumstance occurred, who is a professional man residing in London:—
