As every one knows, or at least as all intelligent people know, the special department in which Gibberne has gained so great and deserved a reputation among physiologists is the action of drugs upon the nervous system. Upon soporifics, sedatives, and anaesthetics he is, I am told, unequalled. He is also a chemist of considerable eminence, and I suppose in the subtle and complex jungle of riddles that centres about the ganglion cell and the axis fibre there are little cleared places of his making, little glades of illumination, that, until he sees fit to publish his results, are still inaccessible to every other living man. And in the last few years he has been particularly assiduous upon this question of nervous stimulants, and already, before the discovery of the New Accelerator, very successful with them. Medical science has to thank him for at least three distinct and absolutely safe invigorators of unrivalled value to practising men. In cases of exhaustion the preparation known as Gibberne's B Syrup has, I suppose, saved more lives already than any lifeboat round the coast. "But none of these little things begin to satisfy me yet," he told me nearly a year ago. "Either they increase the central energy without affecting the nerves, or they simply increase the available energy by lowering the nervous conductivity; and all of them are unequal and local in their operation. One wakes up the heart and viscera and leaves the brain stupefied, one gets at the brain champagne fashion, and does nothing good for the solar plexus, and what I want--and what, if it's an earthly possibility, I mean to have--is a stimulant that stimulates all round, that wakes you up for a time from the crown of your head to the tip of your great toe, and makes you go two--or even three--to everybody else's one. Eh? That's the thing I'm after." "It would tire a man," I said. "Not a doubt of it. And you'd eat double or treble--and all that. But just think what the thing would mean. Imagine yourself with a little phial like this"--he held up a little bottle of green glass and marked his points with it--"and in this precious phial is the power to think twice as fast, move twice as quickly, do twice as much work in a given time as you could otherwise do." "But is such a thing possible?" "I believe so. If it isn't, I've wasted my time for a year. These various preparations of the hypophosphites, for example, seem to show that something of the sort... Even if it was only one and a half times as fast it would do." "It _would_ do," I said. "If you were a statesman in a corner, for example, time rushing up against you, something urgent to be done, eh?" "He could dose his private secretary," I said. "And gain--double time. And think if _you_, for example, wanted to finish a book." "Usually," I said, "I wish I'd never begun 'em." "Or a doctor, driven to death, wants to sit down and think out a case. Or a barrister--or a man cramming for an examination."
