There was a moment of silence, and then, to our amazement and horror, the insect-thing moved, its eyes roving from side to side, its limbs twitching. The thing was alive! The two serpent-creatures stepped toward the case, as it came to life, holding death-beam tubes toward it and addressing it in hissing tones. Apparently it was of some intelligence, for in response to those orders it stepped outside the case, down the hall toward another case which was all but filled by other strange shapes. Into this it stepped, at the command of the two, and then the one with the needle filled it with the green fluid, and inserted this in turn into the thing's body. At once that body stiffened, ceased to move, the thing becoming as rigid and unlife-like in appearance as before, its eyes staring stonily ahead in all the appearance of death. Horror filled me at the sight, horror that sickened me, for I saw now that the things about us, the countless strange shapes in these rows of cases, were all as alive and conscious as ourselves, their life and intelligence unharmed but their bodies thrown into a state of rigid suspended animation by the insertion of the green fluid into them, a fluid that must be like the poisons with which some insects are able to keep their captured prey alive and unmoving indefinitely, a fluid that suspended all animation instantly and that could only be neutralized by the injection of the opposing red fluid, though always the victim remained conscious and alive. _Alive!_ These myriad alien shapes about us--rigid and motionless, yet living and conscious, living perhaps for ages in that living death--my brain reeled at the thought. I turned to Korus Kan, sick with horror, but then stopped short, stiffened. For now the serpent-creature grasping the metal needle and the tube of green fluid was coming toward us! All the horror of the fate intended for us burst across my brain in one flash of awful comprehension, then, and a strangled cry broke from me. "They're going to keep us here too!" I cried, pointing with trembling hand. "Keep us here as strange beings--in living death in this museum of strange beings!" * * * * * A moment we stood, in horror-stricken silence, and then as the full awfulness of the thing reserved for us penetrated the brains of my companions they uttered a medley of hoarse shouts of rage and horror and as one leapt forward upon the serpent-creatures with the fluid-tubes and upon our guards.
