"God, save her!" exclaimed Callirhoë, who in a moment recognized the cruel aspic, of which, as a child, she had been often warned in her native Antioch, and with an eager gesture she flung the venomous reptile to the ground and crushed its head beneath her sandal's heel. On the quick instinct of the moment and without stopping to think of the consequences to herself, she threw her arms about her Imperial mistress' neck, and pressing her lips to her cheek, sucked the venom from the yet bleeding wound.

The cry of the Empress as the little serpent stung her cheek brought a swarm of attendants and slaves into the room, among them black Juba and the officer of the guard who was responsible for the Empress' safety. Valeria had fainted and lay pale as ashes on her couch, a crimson stream flowing from her cheek.

"Dear heart!" exclaimed Juba, with an ostentatious exhibition of well-feigned grief, "let her inhale this fragrant elixir. It is a potent restorative in such deadly faints," and she attempted to complete her desperate crime by thrusting the poisonous perfume under Valeria's nostrils.

"Who was last in the presence before this strange accident—if it be an accident—occurred?" demanded the officer.

"I and Juba, were the only ones," faltered Callirhoë, when a deathly pallor passed over her face, and with a convulsive shudder she fell writhing on the ground.

"You are under arrest," said the officer to. Juba, and then to a soldier of the guard, "Go, seize and seal up her effects—everything she has; and you," turning to another, "send at once the court physician."

The attendants meanwhile were fanning and sprinkling with water the seemingly inanimate forms of the Empress and Callirhoë. When the physician came and felt the fluttering pulse and noted the dilated eyes of his patients, he pronounced it a case of acrid poisoning and promptly ordered antidotes. The Empress, in a few days rallied and seemed little the worse beyond a strange pallor which overspread her features and an abnormal coldness, almost as of death, which pervaded her frame. From these she never fully recovered, but throughout her life was known in popular speech as "The White Lady."

Upon Callirhoë the effects of the poison were still more serious. By her prompt action in sucking the aspic virus from the envenomed wound, she had saved the life of her beloved mistress, but at the peril of her own. The venom coursed through her veins, kindling the fires of fever in her blood. Her dilated eyes shone with unusual brilliance; her speech was rapid; her manner urgent; and her emotions and expressions were characterized by a strange and unwonted intenseness. The physician in answer to the eager questioning of Valeria, gravely shook his head, and said that the case was one that baffled his skill—that cure there was none for the aspic's poison if absorbed into the system, although as it had not in this case been communicated directly to the blood, possibly the youth and vigour of the patient might overcome the toxic effect of the contagium—so he learnedly discoursed.

"My dear child, you have given your life for mine," exclaimed the Empress, throwing her arms around her late enfranchised slave, and bedewing her cheek with her tears.

"God grant it be so," said Callirhoë, with kindling eye. "I would gladly die to save you from a sorrow or a pain. I owe you more than life. I owe you liberty and a life more precious than my own."
