way as Dr. Norbury
turned to him to ask 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 the 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 greyish 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 of the wrappings."

"No: I should say it is a tattoo mark. It is too indefinite for a gilded
device. And I should say further that the tattooing is done in
vermilion, as carbon tattooing would cast no visible shadow."

"I think you must be mistaken about that," said Dr. Norbury, "but we
shall see, if the Director allows us to unroll the mummy. By the way,
those little objects in front of the knees are metallic, I suppose?"

"Yes, they are metallic. But they are not in front of the knees; they
are _in_ the knees. They are pieces of silver wire which have been used
to repair fractured knee-caps."

"Are you sure of that?" exclaimed Dr. Norbury, peering at the little
white marks with ecstasy; "because, if you are, and if these objects are
what you say they are, the mummy of Sebek-hotep is an absolutely unique
specimen."

"I am quite certain of it," said Thorndyke.

"Then," said Dr. Norbury, "we have made a discovery, thanks to your
inquiring spirit. Poor John Bellingham! He little knew what a treasure
he was giving us! How I wish he could have known! How I wish he could
have been here with us to-night!"

He paused once more to gaze in rapture at the photograph. And then
Thorndyke, in his quiet, impassive way, said:

"John Bellingham is
