"What is this?" asked this same surgeon, pointing to the flat of the arm, where the engraved legend was almost obscured with a dark stain.

Hunston changed colour and fidgeted about.

"I don't know."

"There is something written."

"Yes, yes, so I believe, but it is obscured by that stain—a stain—"

He peered closer into the arm yet, and looked serious, as turning to Hunston, he said—

"Why, it is a blood-stain."

"No, no!" replied Hunston, hurriedly; "impossible. It can not be."

"Impossible or not," said the surgeon, "blood it is, and nothing but blood. Yet I see that, in spite of this stain, the reading is clear enough."

"Scarcely," said Hunston.
