She gave a little gasp, and her other hand rested for an instant, as white and as light as thistle-down, upon his shoulder.

"James, James!" she cried. "Don't you see that he is stricken to the heart?"

He turned her quietly away from him.

"I am not an emotional man," he said. "I have my duties--my research on Vallisneria. The brougham is there. Your cloak is in the hall. Tell John where you wish to be driven. He will bring you anything you need. Now go."

His last two words were so sudden, so volcanic, in such contrast to his measured voice and mask- like face, that they swept the two away from him. He closed the door behind them and paced slowly up and down the room. Then he passed into the library and looked out over the wire blind. The carriage was rolling away. He caught a last glimpse of the woman who had been his wife. He saw the feminine droop of her head, and the curve of her beautiful throat.

Under some foolish, aimless impulse, he took a few quick steps towards the door. Then he turned, and throwing himself into his study-chair he plunged back into his work.

There was little scandal about this singular domestic incident. The Professor had few personal friends, and seldom went into society. His marriage had been so quiet that most of his colleagues had never ceased to regard him as a bachelor. Mrs. Esdaile and a few others might talk, but their field for gossip was limited, for they could only guess vaguely at the cause of this sudden separation.

The Professor was as punctual as ever at his classes, and as zealous in directing the laboratory work of those who studied under him. His own private researches were pushed on with feverish energy. It was no uncommon thing for his servants, when they came down of a morning, to hear the shrill scratchings of his tireless pen, or to meet him on the staircase as he ascended, grey and silent, to his room. In vain his friends assured him that such a life must undermine his health. He lengthened his hours until day and night were one long, ceaseless task.

Gradually under this discipline a change came over his appearance. His features, always inclined to gauntness, became even sharper and more pronounced. There were deep lines about his temples and across his brow. His cheek was sunken and his complexion bloodless. His knees gave under him when he walked; and once when passing out of his lecture- room he fell and had to be assisted to his carriage.

This was just before the end of the session and soon after the holidays commenced the professors who still remained in Birchespool were shocked to hear that their brother of the chair of physiology had sunk so low that no hopes could be entertained of his recovery. Two eminent physicians had consulted over his case without being able to give a name to the affection from which he suffered. A steadily decreasing vitality appeared to be the only symptom-- a bodily weakness which left the mind unclouded. He was much interested himself in his own case, and made notes of his subjective sensations as an aid to diagnosis. Of his approaching end he spoke in his usual unemotional and somewhat pedantic fashion.
