aid, its distinctness became less and yet less. Thorndyke
leaned over the tray with his eyes fixed on a point in the middle of
the breast and we all watched him in silence. Suddenly he rose. "Now,
Polton," he said sharply; "get the hypo on as quickly as you can."

Polton, who had been waiting with his hand on the stop-cock of the
drain-tube, rapidly ran off the developer into the bucket and flooded
the paper with the fixing solution.

"Now we can look at it at our leisure," said Thorndyke. After waiting
a few seconds, he switched on one of the glow-lamps, and as the flood
of light fell on the photograph, he added: "You see we haven't quite
lost the skeleton."

"No." Dr. Norbury put on a pair of spectacles and bent down over the
tray; and at this moment I felt Ruth's hand touch my arm, lightly at
first, and then with a strong nervous grasp; and I could feel that her
hand was trembling. I looked round at her anxiously and saw that she
had turned deathly pale.

"Would you rather go out into the gallery?" I asked; for the room with
its tightly shut windows was close and hot.

"No," she replied quietly. "I will stay here. I am quite well." But
still she kept hold of my arm.

Thorndyke glanced at her keenly and then looked away as Dr. Norbury
turned to ask him a question.

"Why is it, think you, that some of the teeth show so much whiter than
others?"

"I think the whiteness of the shadows is due to the presence of metal,"
Thorndyke replied.

"Do you mean that the teeth have metal fillings?" asked Dr. Norbury.

"Yes."

"Really! This is very interesting. The use of gold stoppings--and
artificial teeth, too--by the ancient Egyptians is well known, but we
have no examples in this Museum. This mummy ought to be unrolled. Do
you think all those teeth are filled with the same metal? They are not
equally white."

"No," replied Thorndyke. "Those teeth that are perfectly white are
undoubtedly filled with gold, but that grayish one is probably filled
with tin."

"Very interesting," said Dr. Norbury. "_Very_ interesting! And what
do you make of that faint mark across the chest, near the top of the
sternum?"

It was Ruth who answered his question.

"It is the Eye of Osiris!" she exclaimed in a hushed voice.

"Dear me!" exclaimed Dr. Norbury, "so it is. You are quite right. It
is the Utchat--the Eye of Horus--or Osiris, if you prefer to call it
so. That, I presume, will be a gilded device on some
