"I found on microscopic examination that it was an uncommon linen
bond paper, and I have taken a large number of microphotographs
of the fibres in it. They are all similar. I have here also about
a hundred microphotographs of the fibres in other kinds of paper,
many of them bonds. These I have accumulated from time to time in
my study of the subject. None of them, as you can see, shows
fibres resembling this one in question, so we may conclude that
it is of uncommon quality. Through an agent of the police I have
secured samples of the notepaper of every one who could be
concerned, as far as I could see, with this case. Here are the
photographs of the fibres of these various notepapers, and among
them all is just one that corresponds to the fibres in the wet
mass of paper I discovered in the scrap-basket. Now lest anyone
should question the accuracy of this method I might cite a case
where a man had been arrested in Germany charged with stealing a
government bond. He was not searched till later. There was no
evidence save that after the arrest a large number of spitballs
were found around the courtyard under his cell window. This
method of comparing the fibres with those of the regular
government paper was used, and by it the man was convicted of
stealing the bond.
