"Yes, Ada; I slept badly. Some little cerebral congestion, no doubt due to over-stimulation of the centres of thought. I have been a little disturbed in my mind."
His sister stared across at him in astonishment. The Professor's mental processes had hitherto been as regular as his habits. Twelve years' continual intercourse had taught her that he lived in a serene and rarefied atmosphere of scientific calm, high above the petty emotions which affect humbler minds.
"You are surprised, Ada," he remarked. "Well, I cannot wonder at it. I should have been surprised myself if I had been told that I was so sensitive to vascular influences. For, after all, all disturbances are vascular if you probe them deep enough. I am thinking of getting married."
"Not Mrs. O'James?" cried Ada Grey, laying down her egg-spoon.
"My dear, you have the feminine quality of receptivity very remarkably developed. Mrs. O'James is the lady in question."
"But you know so little of her. The Esdailes themselves know so little. She is really only an acquaintance, although she is staying at The Lindens. Would it not be wise to speak to Mrs. Esdaile first, John?"
"I do not think, Ada, that Mrs. Esdaile is at all likely to say anything which would materially affect my course of action. I have given the matter due consideration. The scientific mind is slow at arriving at conclusions, but having once formed them, it is not prone to change. Matrimony is the natural condition of the human race. I have, as you know, been so engaged in academical and other work, that I have had no time to devote to merely personal questions. It is different now, and I see no valid reason why I should forego this opportunity of seeking a suitable helpmate."
"And you are engaged?"
"Hardly that, Ada. I ventured yesterday to indicate to the lady that I was prepared to submit to the common lot of humanity. I shall wait upon her after my morning lecture, and learn how far my proposals meet with her acquiescence. But you frown, Ada!"
His sister started, and made an effort to conceal her expression of annoyance. She even stammered out some few words of congratulation, but a vacant look had come into her brother's eyes, and he was evidently not listening to her.
