"I was there when this happened, said Mademoiselle G., and it was the talk of the town; almost everybody laughed at him; but five days afterwards the Duke fell suddenly ill, and was found to be in so dangerous a state, that the physicians forbade his being removed into the town. He finally died at the Belvedere, and was buried in the Russian chapel, exactly in the manner pourtrayed by the shadowy forms seen by the sentinel, and there buried." We all agreed that these rehearsals, if we may so call them, are amongst the most perplexing of these very perplexing phenomena; a very curious case of this description will be found in one of the letters inserted in the Appendix. "My sister-in-law, Lady S.," said Lady R., "Told me, the other day, that during her late residence in St. Petersburg, she was intimately acquainted with a Prussian lady of high rank, to whom the following strange events occurred, an account of which she herself gave to my sister.

A scream brought her husband, who was in the adjoining room, and he saw the figure as well as herself. Nevertheless, the fear of ridicule kept them silent; but some time afterwards, when they had a party, one of the company exclaimed, 'Good Heavens! This, I remember, is the very room that unfortunate Chasseurs hung himself in!' And then they learned that the house had been previously occupied by the Danish minister, and that a Chasseur in his service had, from some cause or other, committed suicide." "I don't know whether dreams are admissible," said Miss M.; "but the sort of occurrences just related appear to me to be little removed from waking dreams. I know two cases of extraordinary dreaming, the authenticity of which I can answer for, if you would like to hear them." We accepted gladly, and the lady began as follows:--
