There was another exclamation. No sooner was it observed, than the likeness to Rêve de Noir seemed to be even more perfect.

The Duke made a sign.

Rêve de Noir placed himself near the canvas. His profile was the counterpart of that in the painting. He seemed to have stepped out of it.

"It was I," said the Duke, in a gentle voice, and with a smile which just disclosed the ivory line under the black moustache, "who caused this picture to be copied and altered. The beauty of the Hon. Mrs. Denslow, whom it was my highest pleasure to know, seemed to me to surpass that of the queen of my original. I first, with great secrecy, unknown to your wife," continued the Duke, turning to Denslow, "procured a portrait from the life by memory, which was afterwards transferred to this canvas. The resemblance to my attendant is, I confess, remarkable and inexplicable."

"But will you tell us by what accident this copy happened to be in Italy?" asked Dalton.

"You will remember," replied the Duke, coldly, "that at Paris, noticing your expressions of admiration for the picture, which you had seen in my English gallery, I gave you a history of its purchase at Bologna by myself. I sent my artist to Bologna, with orders to place the copy in the gallery and to introduce the portrait of the lady; it was a freak of fancy; I meant it for a surprise; as I felt sure, that, if you saw the picture, you would secure it.

"It seems to me," replied Dalton, "that the onus of proof rests with your Highness."

The Duke made a signal to Rêve de Noir, who again stepped up to the canvas, and, with a short knife or stiletto, removed a small portion of the outer layer of paint, disclosing a very ancient ground of some other and inferior work, over which the copy seemed to have been painted. The proof was unanswerable.

"Good copies," remarked the Duke, "are often better than originals."

He offered his arm to Honoria, and they walked through the gallery,—he entertaining her, and those near him, with comments upon other works. The crowd followed them, as they moved on or returned, as a cloud of gnats follow up and down, and to and fro, a branch tossing in the wind.
