The Professor raised his head, and his look of astonishment brought Ilse to her senses.

"Forgive me," she said, feebly; "I was thinking."

"What is the matter. Ilse?" he asked, kindly; "your cheeks are hot. Are you ill?"

"It will pass over; have patience with me."

The Professor left his book, and occupied himself anxiously about his wife.

"Open the window," she said softly. "The air of the close room feels heavy to me."

He was so tenderly concerned about her that she again looked cheerfully at him.

"It was a foolish weakness, Felix; it has passed away."
