Were these the beings of the new planet which had come to attack us? But how could this helpless creature, incapable of almost everything, obviously, save thought, do the work of its world? Then I recalled again that insulated room of the Red Spark Cafe: the thin, ten-foot hooded shape which was carrying the box. Was that, perhaps, an opposite type of being with the brain submerged, dwarfed, and the body paramount? Were there, on this mysterious planet, two co-existing types, each a specialist, one for the physical work and the other for the mental? I stood with Snap and Grantline in that dark balcony doorway, gazing down to where the giant brain stood braced upon its shriveled arms and legs, and realized why we of Earth and Venus and Mars are all cast in the same mould we call human. It is a little family of planets, here in our solar system; for countless eons we have been close neighbors. The same sunlight, the same general conditions of life, the same seed, were strewn here by a wise Creator. A man from the Orient is different from an Anglo-Saxon; a man of Mars differs a little more. But basically they are the same. Yet, confronting us now was a new type, from realms of interstellar space, far beyond our solar system. "For the last time, will you talk?" snapped Brayley. There was another interval of silence. The eyes of the brain were very watchful. Its gaze roved the hall as though it were seeking for help. It shifted its little arms on the table, seemingly exhausted from the physical effort of supporting itself. Brayley's voice came again. "Doubtless you can feel pain acutely. We shall see." With what effort of will to overcome his revulsion we may only guess, he reached forward and pinched the little arm. The result was electrifying. From the upended slit of mouth in that goggling face, came a scream. It pierced the heavy tense silence of the hall, ghastly in its timbre, like nothing any of us had ever heard before. And in it was conveyed agony as though Brayley had not merely pinched that flabby arm, but had thrust a red-hot knife into its vitals. The brain could feel pain indeed. It crouched with stiffened arms and legs. The membrane of its great head seemed to bulge with greater distension; the knotted blood-vessels were gorged with purple blood. The eyes rolled. Then it closed its mouth. Its gaze steadied upon Brayley's face, so baleful a gaze that as I could see the reflection of its luminous purple glow a shudder of fear and revulsion swept me. "So you did not like that?" Brayley steadied his voice. "If you don't want more, you had better speak. How did you get here on Earth? What are you trying to do here?" There seemed an interminable silence; then Nippor took a menacing step forward. "Speak! We will force it from you!" And then it spoke. "Do--not--touch--me--again."
