r the night.

There, sir, I have told you the whole story of the events which led up
to the murder of Lord Mannering by his wife upon the night of September
the 14th, in the year 1894. Perhaps you will put my statement on one
side as the constable did at Mannering Towers, or the judge afterwards
at the county assizes. Or perhaps you will see that there is the ring of
truth in what I say, and you will follow it up, and so make your name
for ever as a man who does not grudge personal trouble where justice is
to be done. I have only you to look to, sir, and if you will clear my
name of this false accusation, then I will worship you as one man never
yet worshipped another. But if you fail me, then I give you my solemn
promise that I will rope myself up, this day month, to the bar of my
window, and from that time on I will come to plague you in your dreams
if ever yet one man was able to come back and to haunt another. What I
ask you to do is very simple. Make inquiries about this woman, watch
her, learn her past history, find out what she is making of the money
which has come to her, and whether there is not a man Edward as I have
stated. If from all this you learn anything which shows you her real
character, or which seems to you to corroborate the story which I have
told you, then I am sure that I can rely upon your goodness of heart to
come to the rescue of an innocent man.

THE GREAT KEINPLATZ EXPERIMENT

Of all the sciences which have puzzled the sons of men, none had such an
attraction for the learned Professor von Baumgarten as those which
relate to psychology and the ill-defined relations between mind and
matter. A celebrated anatomist, a profound chemist, and one of the first
physiologists in Europe, it was a relief for him to turn from these
subjects and to bring his varied knowledge to bear upon the study of the
soul and the mysterious relationship of spirits. At first, when as a
young man he began to dip into the secrets of mesmerism, his mind seemed
to be wandering in a strange land where all was chaos and darkness, save
that here and there some great unexplainable and disconnected fact
loomed out in front of him. As the years passed, however, and as the
worthy Professor's stock of knowledge increased, for knowledge begets
knowledge as money bears interest, much which had seemed strange and
unaccountable began to take another shape in his eyes. New trains of
reasoning became familiar to him, and
