for the complete absence of the furniture that impedes free motion in our European houses and made me think as I awoke in my chamber of our great cathedrals with their free floor space. There in mid-air we lightly hung as if resting on wings; he seemed to know my anatomy and the points of greatest pressure in any attitude, and controlled both machine-rests with such adroitness that we swung hither and thither, changing slowly from the recumbent to the erect attitude or back again, finding every few minutes a different point of view of the chamber or of the landscapes that could be seen through the walls. But I soon grew oblivious to the beauty that stole through every sense; my whole consciousness was absorbed in watching the play of the intelligence on his face and listening to his narrative. I missed many of the links in his story, even though he contrived to put most of it into the primary and secondary vocabularies, and, where he was compelled to go beyond them, put so much of his thoughts into his features that I could almost have gathered it from them. But I saw the drift of the story, and, when it was over, pieced the fragments together and found, when afterwards I knew the language and the civilisation better, I had missed little of the real meaning. I give it, then, as if it were in his own words, although my intelligence seemed to stumble at every step in it. “You wonder at your hospitable reception. But you will not wonder when you know the change in the condition of our knowledge since Noola was exiled. He was unhurt by the ricochet of the missiles on the beach. In the darkness they were ill-aimed, and, though they struck in sand, they were shattered by the impact and recoiled from the shingle underneath. He disentangled himself from the wreck and rescued you. But soon the watchers by the storm-cone were down on the beach and carried you to our house, whilst they led your comrade to another. You were each examined by the wise men and the medical families. Your faculties and emotions and tendencies were all tested, and their various strengths measured by means of the different kinds of cerebrometers whilst you slept. Since Noola was exiled a hundred years ago, our knowledge of the brain and the nerves and their various functions has been applied in the most practical way to the art of living. Every curve and convolution of the controlling instrument of the body has its value and meaning tabulated. Every action, thought, and emotion has had its physical symbol and locality fixed; and the minutest change in the strength of any one of these points in the brain or in the nervous system can be discovered by applying one of the cerebrometers. You will know what these are some day; but it is enough to say that they can measure, by means of a delicate apparatus controlled by electricity, the amount of force that exists in any living tissue; there is a separate kind for each portion of the brain and each nerve section of
