“The _First_ Axiom,” the Professor read out in a great hurry, “consists of these words, ‘_Whatever is, is_.’ And the Second consists of _these_ words, ‘_Whatever isn’t, isn’t_.’ We will now go on to the _Specimens_. The first tray contains Crystals and other Things.” He drew it towards him, and again referred to his note-book. “Some of the labels—owing to insufficient adhesion——” Here he stopped again, and carefully examined the page with his eyeglass. “I ca’n’t quite read the rest of the sentence,” he said at last, “but it _means_ that the labels have come loose, and the Things have got mixed——” “Let _me_ stick ’em on again!” cried Bruno eagerly, and began licking them, like postage-stamps, and dabbing them down upon the Crystals and the other Things. But the Professor hastily moved the tray out of his reach. “They _might_ get fixed to the _wrong_ Specimens, you know!” he said. “Oo shouldn’t have any _wrong_ peppermints in the tray!” Bruno boldly replied. “_Should_ he, Sylvie?” But Sylvie only shook her head. The Professor heard him not. He had taken up one of the bottles, and was carefully reading the label through his eye-glass. “Our first Specimen——” he announced, as he placed the bottle in front of the other Things, “is—that is, it is called——” here he took it up, and examined the label again, as if he thought it might have changed since he last saw it, “is called Aqua Pura—common water—the fluid that cheers——” “Hip! Hip! Hip!” the Head-Cook began enthusiastically. “—but _not_ inebriates!” the Professor went on quickly, but only just in time to check the “Hooroar!” which was beginning. “Our second Specimen,” he went on, carefully opening a small jar, “is——” here he removed the lid, and a large beetle instantly darted out, and with an angry buzz went straight out of the Pavilion, “—is—or rather, I should say,” looking sadly into the empty jar, “it _was_—a curious kind of Blue Beetle. Did any one happen to remark—as it went past—three blue spots under each wing?” Nobody had remarked them. “Ah, well!” the Professor said with a sigh. “It’s a pity. Unless you remark that kind of thing _at the moment_, it’s very apt to get overlooked! The _next_ Specimen, at any rate, will not fly away! It is—in short, or perhaps, more correctly, at _length_—an _Elephant_. You will observe——.” Here he beckoned to the Gardener to come up on the platform, and with his help began putting together what looked like an enormous dog-kennel, with short tubes projecting out of it on both sides. “But we’ve seen _Elephants_ before,” the Emperor grumbled.
