Barker rose to go; but Claudius was begging him not to hurry, when there was another knock, and the Duke entered. He shook hands with Claudius, and spoke rather coldly to Barker. The latter was uneasy, and felt that he was in the way. He was. Barker had fallen into a singular error of judgment in regard to the relations existing between the Duke and Claudius. He had imagined it in his power to influence the Duke's opinion, whereas in trying to effect that object he had roused the Englishman's animosity. Besides, Mr. Barker was to the Duke a caprice. He found the quick-thinking man of business amusing and even useful, but for steady companionship he did not want him. A passage across the Atlantic was more than enough to satisfy his desire for Mr. Barker's society, even if Barker had not managed to excite his indignation. But Claudius was different. The honest nobleman could not tell why it was, but it was true, nevertheless. He looked upon the Doctor more as an equal than Barker. The Duke was a very great man in his own country, and it was singular indeed that he should find a man to his liking, a man who seemed of his own caste and calibre, in the simple privat-docent of a German university. Perhaps Barker felt it too. At all events, when the Duke sat himself down in Claudius's room, after begging permission to ring for lights, and made himself most evidently at home, Mr. Barker felt that he was in the way; and so, promising to call on Claudius again in the morning, he departed. Claudius stood by the mantelpiece while the servant lit the gas.

"I am very glad to see you," he said, when the man had gone.

"I am glad of that, for I want your society. The Countess Margaret has a headache, and Lady Victoria has gone to dine in her rooms, and to spend the evening with her."

"I am very sorry to hear that the Countess is not well," said Claudius, "but I am very glad of anything that brings you here to-night. I am in trouble—that is, I have been very much annoyed."

"Ah, very sorry," said the Duke.

"It so happens that you are the only person in America, as far as I know, who can help me."

"I?" The Duke opened his eyes wide. Then he reflected that it might be something concerning the Countess, and waited.

"You are a gentleman," said Claudius reflectively, and hardly addressing his visitor as he said it.

"Quite so," said the Duke. "It's a very fine word that."

"And a man of honour," continued Claudius in a meditative tone.
