I will not trouble you with all the details of Sebastian's further researches; the curious will find them discussed at length in Volume 237 of the Philosophical Transactions. (See also Comptes Rendus de l'Academie de Medecine: tome 49, pp. 72 and sequel.) I will restrict myself here to that part of the inquiry which immediately refers to Hilda Wade's history.
“If I were you,” she said to the Professor one morning, when he was most astonished at his contradictory results, “I would test it on a hawk. If I dare venture on a suggestion, I believe you will find that hawks recover.”
“The deuce they do!” Sebastian cried. However, he had such confidence in Nurse Wade's judgment that he bought a couple of hawks and tried the treatment on them. Both birds took considerable doses, and, after a period of insensibility extending to several hours, woke up in the end quite bright and lively.
“I see your principle,” the Professor broke out. “It depends upon diet. Carnivores and birds of prey can take lethodyne with impunity; herbivores and fruit-eaters cannot recover, and die of it. Man, therefore, being partly carnivorous, will doubtless be able more or less to stand it.”
Hilda Wade smiled her sphinx-like smile. “Not quite that, I fancy,” she answered. “It will kill cats, I feel sure; at least, most domesticated ones. But it will NOT kill weasels. Yet both are carnivores.”
“That young woman knows too much!” Sebastian muttered to me, looking after her as she glided noiselessly with her gentle tread down the long white corridor. “We shall have to suppress her, Cumberledge.... But I'll wager my life she's right, for all that. I wonder, now, how the dickens she guessed it!”
“Intuition,” I answered.
He pouted his under lip above the upper one, with a dubious acquiescence. “Inference, I call it,” he retorted. “All woman's so-called intuition is, in fact, just rapid and half-unconscious inference.”
He was so full of the subject, however, and so utterly carried away by his scientific ardour, that I regret to say he gave a strong dose of lethodyne at once to each of the matron's petted and pampered Persian cats, which lounged about her room and were the delight of the convalescents. They were two peculiarly lazy sultanas of cats—mere jewels of the harem—Oriental beauties that loved to bask in the sun or curl themselves up on the rug before the fire and dawdle away their lives in congenial idleness. Strange to say, Hilda's prophecy came true. Zuleika settled herself down comfortably in the Professor's easy chair and fell into a sound sleep from which there was no awaking; while Roxana met fate on the tiger-skin she loved, coiled up in a circle, and passed from this life of dreams, without knowing it, into one where dreaming is not. Sebastian noted the facts with a quiet gleam of satisfaction in his watchful eye, and explained afterwards, with curt glibness to the angry matron, that her favourites had been “canonised in the roll of science, as painless martyrs to the advancement of physiology.”
The weasels, on the other hand, with an equal dose, woke up after six hours as lively as crickets. It was clear that carnivorous tastes were not the whole solution, for Roxana was famed as a notable mouser.
“Your principle?” Sebastian asked our sibyl, in his brief, quick way.
Hilda's cheek wore a glow of pardonable triumph. The great teacher had deigned to ask her assistance. “I judged by the analogy of Indian hemp,” she answered. “This is clearly a similar, but much stronger, narcotic. Now, whenever I have given Indian hemp by your direction to people of sluggish, or even of merely bustling temperament, I have noticed that small doses produce serious effects, and that the after-results are most undesirable. But when you have prescribed the hemp for nervous, overstrung, imaginative people, I have observed that they can stand large amounts of the tincture without evil results, and that the after-effects pass off rapidly. I who am mercurial in temperament, for example, can take any amount of Indian hemp without being made ill by it; while ten drops will send some slow and torpid rustics mad drunk with excitement—drive them into homicidal mania.”
Sebastian nodded his head. He needed no more explanation. “You have hit it,” he said. “I see it at a glance. The old antithesis! All men and all animals fall, roughly speaking, into two great divisions of type: the impassioned and the unimpassioned; the vivid and the phlegmatic. I catch your drift now. Lethodyne is poison to phlegmatic patients, who have not active power enough to wake up from it unhurt; it is relatively harmless to the vivid and impassioned, who can be put asleep by it, indeed, for a few hours more or less, but are alive enough to live on through the coma and reassert their vitality after it.”
I recognised as he spoke that this explanation was correct. The dull rabbits, the sleepy Persian cats, and the silly sheep had died outright of lethodyne; the cunning, inquisitive raccoon, the quick hawk, and the active, intense-natured weasels, all most eager, wary, and alert animals, full of keenness and passion, had recovered quickly.
“Dare we try it on a human subject?” I asked, tentatively.
Hilda Wade answered at once, with that unerring rapidity of hers: “Yes, certainly; on a few—the right persons. I, for one, am not afraid to try it.”
“You?” I cried, feeling suddenly aware how much I thought of her. “Oh, not YOU, please, Nurse Wade. Some other life, less valuable!”
Sebastian stared at me coldly. “Nurse Wade volunteers,” he said. “It is in the cause of science. Who dares dissuade her? That tooth of yours? Ah, yes. Quite sufficient excuse. You wanted it out, Nurse Wade. Wells-Dinton shall operate.”
Without a moment's hesitation, Hilda Wade sat down in an easy chair and took a measured dose of the new anaesthetic, proportioned to the average difference in weight between raccoons and humanity. My face displayed my anxiety, I suppose, for she turned to me, smiling with quiet confidence. “I know my own constitution,” she said, with a reassuring glance that went straight to my heart. “I do not in the least fear.”
As for Sebastian, he administered the drug to her as unconcernedly as if she were a rabbit. Sebastian's scientific coolness and calmness have long been the admiration of younger practitioners.
Wells-Dinton gave one wrench. The tooth came out as though the patient were a block of marble. There was not a cry or a movement, such as one notes when nitrous oxide is administered. Hilda Wade was to all appearance a mass of lifeless flesh. We stood round and watched. I was trembling with terror. Even on Sebastian's pale face, usually so unmoved, save by the watchful eagerness of scientific curiosity, I saw signs of anxiety.
After four hours of profound slumber—breath hovering, as it seemed, between life and death—she began to come to again. In half an hour more she was wide awake; she opened her eyes and asked for a glass of hock, with beef essence or oysters.
That evening, by six o'clock, she was quite well and able to go about 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
