Mercy was silent.

Whitworth. I must press for a reply, that we may know what value to attach to your most extraordinary evidence. Were you his wife—or his mistress?

Mercy. Indeed I hardly know; but not his mistress, or I should not be here.

Whitworth. You don't know whether you were married to the man or not?

Mercy. I do not say so. But—

She hesitated, and cast a piteous look at Mrs. Gaunt, who sat boiling with indignation.

At this look, the prisoner, who had long contained herself with difficulty, rose, with scarlet cheeks and flashing eyes, in defense of her witness, and flung her prudence to the wind.

"Fie, sir," she cried. "The woman you insult is as pure as your own mother, or mine. She deserves the pity, the respect, the veneration of all good men. Know, my lord, that my miserable husband deceived and married her under the false name he had taken; she has the marriage certificate in her bosom. Pray make her show it whether she will or not. My lord, this Mercy Vint is more an angel than a woman. I am her rival after a manner; yet out of the goodness and greatness of her noble heart, she came all that way to save me from an unjust death. And is such a woman to be insulted? I blush for the hired advocate who cannot see his superior in an incorruptible witness, a creature all truth, piety, purity, unselfishness, and goodness. Yes, sir, you began by insinuating that she was as venal as yourself; for you are one that can be bought by the first comer; and now you would cast a slur on her chastity, For shame! for shame! This is one of those rare women that adorn our whole sex, and embellish human nature: and, so long as you have the privilege of exchanging words with her, I shall stand here on the watch, to see that you treat her with due respect: ay, sir, with reverence; for I have measured you both, and she is as much your superior as she is mine."

This amazing burst was delivered with such prodigious fire and rapidity, that nobody was self-possessed enough to stop it in time. It was like a furious gust of words sweeping over the court.

Mr. Whitworth, pale with auger, merely said, "Madam, the good taste of these remarks I leave the court to decide upon. But you cannot be allowed to give evidence in your own defense."
