Felton stared at him in
speechless wonder. "You notice it is a left horn, and you remember that
it was highly sensitive. If you put your ear to it while I strain it,
you will hear the grating of a fracture in the bony core. Now look at
the pointed end, and you will see several deep scratches running
lengthwise, and where those scratches end the diameter of the horn is,
as you see by this calliper-gauge, one inch and seven-sixteenths.
Covering the scratches is a dry blood-stain, and at the extreme tip is a
small mass of a dried substance which Dr. Jervis and I have examined
with the microscope and are satisfied is brain tissue."
"Good God!" exclaimed Stopford eagerly. "Do you mean to say--"
"Let us finish with the facts, Mr. Stopford," Thorndyke interrupted.
"Now, if you look closely at that blood-stain, you will see a short
piece of hair stuck to the horn, and through this lens you can make out
the root-bulb. It is a golden hair, you notice, but near the root it is
black, and our calliper-gauge shows us that the black portion is
fourteen sixty-fourths of an inch long. Now, in this envelope are some
hairs that I removed from the dead woman's head.
