in fact, than McLaughlin had already said about the beasts. On the other hand, it had been distinctly informative to read that a small, salamanderlike thing in one of the glass-fronted cages was as poisonous as the most dangerous of Terrestrial snakes. There had been nothing in its appearance to betray the fact. It was at this point, in fact, that Lampert began really to awaken to what he was doing. He was aroused all the way by McLaughlin's explanation of a number which appeared on a good many of the placards. Lampert had noticed it already. The number was always, it seemed, different, though always in the same place, and bore signs of much repainting. It bore no relationship to any classification scheme that Lampert knew, and neither of the paleontologists could enlighten him. Eventually he turned to McLaughlin and asked—not expecting a useful answer, since the man was a guide rather than a naturalist. However, the tall man gave a faint smile and replied without hesitation. "That's just the number of human deaths known to have been caused by that animal this year." It did not comfort Lampert too greatly to learn that the year used was that of Viridis, some seventeen times as long as that of Earth. For the Felodon the number stood at twelve. This was not very much when compared to the annual losses from tigers in India during the nineteenth century. But this reflection was not particularly consoling. The human population of Viridis was so very small compared to that of India. Lampert examined the creature thoughtfully. It was of moderate size as carnivores went—some four feet long without the tail—and looked rather harmless as long as it kept its mouth shut. It was lying in the center of the cage, so it was difficult to judge the length of its legs. It showed no trace of the tendency displayed by many captive animals, of lying against a wall or in a corner when relaxed; and there was none of the restless pacing so characteristic of Earth's big cats under similar circumstances. It simply lay and stared back at Lampert, so steadily that he never was sure whether or not the cold eyes were provided with lids. "I never liked reptiles back home, but I think I like these creatures less." The voice of Mitsuitei, the little archaeologist, cut into Lampert's reverie. "Don't let Hans or Ndomi hear you mention them in the same breath with reptiles," he answered. "Well, I'm not fond of frogs, either."
