"The whole aspect of this monster was formidable and threatening, and it kept changing its colour from a very light mauve to a dark, angry purple so thick that it cast a shadow as it drifted between my monoplane and the sun. On the upper curve of its huge body there were three great projections which I can only describe as enormous bubbles, and I was convinced as I looked at them that they were charged with some extremely light gas which served to buoy-up the misshapen and semi-solid mass in the rarefied air. The creature moved swiftly along, keeping pace easily with the monoplane, and for twenty miles or more it formed my horrible escort, hovering over me like a bird of prey which is waiting to pounce. Its method of progression--done so swiftly that it was not easy to follow--was to throw out a long, glutinous streamer in front of it, which in turn seemed to draw forward the rest of the writhing body. So elastic and gelatinous was it that never for two successive minutes was it the same shape, and yet each change made it more threatening and loathsome than the last. "I knew that it meant mischief. Every purple flush of its hideous body told me so. The vague, goggling eyes which were turned always upon me were cold and merciless in their viscid hatred. I dipped the nose of my monoplane downwards to escape it. As I did so, as quick as a flash there shot out a long tentacle from this mass of floating blubber, and it fell as light and sinuous as a whip-lash across the front of my machine. There was a loud hiss as it lay for a moment across the hot engine, and it whisked itself into the air again, while the huge flat body drew itself together as if in sudden pain. I dipped to a vol-pique, but again a tentacle fell over the monoplane and was shorn off by the propeller as easily as it might have cut through a smoke wreath. A long, gliding, sticky, serpent-like coil came from behind and caught me round the waist, dragging me out of the fuselage. I tore at it, my fingers sinking into the smooth, glue-like surface, and for an instant I disengaged myself, but only to be caught round the boot by another coil, which gave me a jerk that tilted me almost on to my back.
