her duties as usual. "Sebastian is a wonderful man," I said to her, as I entered her ward on my rounds at night. "His coolness astonishes me. Do you know, he watched you all the time you were lying asleep there as if nothing were the matter." "Coolness?" she inquired, in a quiet voice. "Or cruelty?" "Cruelty?" I echoed, aghast. "Sebastian cruel! Oh, Nurse Wade, what an idea! Why, he has spent his whole life in striving against all odds to alleviate pain. He is the apostle of philanthropy!" "Of philanthropy, or of science? To alleviate pain, or to learn the whole truth about the human body?" "Come, come, now," I cried. "You analyse too far. I will not let even YOU put me out of conceit with Sebastian." (Her face flushed at that "even you"; I almost fancied she began to like me.) "He is the enthusiasm of my life; just consider how much he has done for humanity!" She looked me through searchingly. "I will not destroy your illusion," she answered, after a pause. "It is a noble and generous one. But is it not largely based on an ascetic face, long white hair, and a moustache that hides the cruel corners of the mouth? For the corners ARE cruel. Some day, I will show you them. Cut off the long hair, shave the grizzled moustache--and what then will remain?" She drew a profile hastily. "Just that," and she showed it me. 'Twas a face like Robespierre's, grown harder and older and lined with observation. I recognised that it was in fact the essence of Sebastian. Next day, as it turned out, the Professor himself insisted upon testing lethodyne in his own person. All Nat's strove to dissuade him. "Your life is so precious, sir--the advancement of science!" But the Professor was adamantine. "Science can only be advanced if men of science will take their lives in their hands," he answered, sternly. "Besides, Nurse Wade has tried. Am I to lag behind a woman in my devotion to the cause of physiological knowledge?" "Let him try," Hilda Wade murmured to me. "He is quite right. It will not hurt him. I have told him already he has just the proper temperament to stand the drug. Such people are rare: HE is one of them." We administered the dose, trembling. Sebastian took it like a man, and dropped off instantly, for lethodyne is at least as instantaneous in its operation as nitrous oxide. He lay long asleep. Hilda and I watched him.
