again the marks of the
accused, but not placing them in the same order or relation to the other
signatures as before--for, by one chance in a million, a person might
happen upon the right marks by pure guesswork, ONCE, therefore I wish to
be tested twice."

He turned his back, and the two panes were quickly covered with
delicately lined oval spots, but visible only to such persons as could
get a dark background for them--the foliage of a tree, outside, for
instance. Then upon call, Wilson went to the window, made his
examination, and said:

"This is Count Luigi's right hand; this one, three signatures below, is
his left. Here is Count Angelo's right; down here is his left. Now for
the other pane: here and here are Count Luigi's, here and here are his
brother's." He faced about. "Am I right?"

A deafening explosion of applause was the answer. The bench said:

"This certainly approaches the miraculous!"

Wilson turned to the window again and remarked, pointing with his finger:

"This is the signature of Mr. Justice Robinson. [Applause.] This, of
Constable Blake. [Applause.] This of John Mason, juryman. [Applause.]
This, of the sheriff. [Applause.] I cannot name the others, but I have
them all at home, named and dated, and could identify them all by my
fingerprint records."

He moved to his place through a storm of applause--which the sheriff
stopped, and also made the people sit down, for they were all standing
and struggling to see, of course. Court, jury, sheriff, and everybody
had been too absorbed in observing Wilson's performance to attend to the
audience earlier.

"Now then," said Wilson, "I have here the natal autographs of the two
children--thrown up to ten times the natural size by the pantograph, so
that anyone who can see at all can tell the markings apart at a glance.
We will call the children A and B. Here are A's finger marks, taken at
the age of five months. Here they are again taken at seven months. [Tom
started.] They are alike, you see. Here are B's at five months, and also
at seven months. They, too, exactly copy each other, but the patterns
are quite different from A's, you observe. I shall refer to these again
presently, but we will turn them face down now.

"Here, thrown up ten sizes, are the natal autographs of the two persons
who are here before you accused of murdering Judge Driscoll. I made these
pantograph copies last night, and will so swear when I go upon the
witness
