“She is waiting beside me and will presently re-enter her own frame. As to you, sir,” turning to Challenger, “you are a man of character and learning, but you are clearly embedded in that materialism which is the special curse of your age. Let me assure you that the medical profession, which is supreme upon earth for the disinterested work of its members, has yielded too much to the dogmatism of such men as you, and has unduly neglected that spiritual element in man which is far more important than your herbs and your minerals. There is a life-force, sir, and it is in the control of this life-force that the medicine of the future lies. If you shut your mind to it it can only mean that the confidence of the public will turn to those who are ready to adopt every means of cure, whether they have the approval of your authorities or not.” Never could young Ross Scotton forget that scene. The Professor, the master, the supreme chief, he who had to be addressed with bated breath, sat with half-opened mouth and staring eyes, leaning forward in his chair, while in front of him the slight young woman, shaking her mop of brown hair and wagging an admonitory forefinger, spoke to him as a father speaks to a refractory child. So intense was her power that Challenger, for the instant, was constrained to accept the situation. He gasped and grunted, but no retort came to his lips. The girl turned away and sat down on a chair. “He is going,” said Miss Delicia. “But not yet gone,” replied the girl with a smile. “Yes, I must go, for I have much to do. This is not my only medium of expression and I am due in Edinburgh in a few minutes. But be of good heart, young man. I will set my assistant with two extra batteries to increase your vitality so far as your system will permit. As to you, sir,” to Challenger, “I would implore you to beware of the egotism of brain and the self-concentration of intellect. Store what is old, but be ever receptive to what is new, and judge it not as you may wish it, but as God has designed it.” She gave a deep sigh and sank back in her chair. There was a minute of dead silence while she lay with her head upon her breast. Then with another sigh and a shiver she opened a pair of very bewildered blue eyes. “Well, has he been?” she asked in a gentle feminine voice. “Indeed, yes!” cried the patient. “He was great. He says I shall be in the class-room in two months.” “Splendid! Any directions for me?” “Just the special message as before. But he is going to put on two new spirit batteries if I can stand it.” “My word, he won’t be long now!” Suddenly the girl’s eyes lit on Challenger and she stopped in confusion. “This is Nurse Ursula,” said Miss Delicia. “Nurse, let me present you to the famous Professor Challenger.”
