Day followed day, and still there was no cessation of the professor’s discomposure. He was the most miserable of mortals. If really his calculations and his observations were at variance, this, in a man of his irritable temperament, would account for his perpetual perturbation. But he entered into no explanation; he only climbed up to his telescope, looking haggard and distressed, and when compelled by the frost to retire, he would make his way back to his study more furious than ever. At times he was heard giving vent to his vexation. “Confound it! what does it mean? what is she doing? All behind! Is Newton a fool? Is the law of universal gravitation the law of universal nonsense?” And the little man would seize his head in both his hands, and tear away at the scanty locks which he could ill afford to lose. Enough was overheard to confirm the suspicion that there was some irreconcilable discrepancy between the results of his computation and what he had actually observed; and yet, if he had been called upon to say, he would have sooner insisted that there was derangement in the laws of celestial mechanism, than have owned there was the least probability of error in any of his own calculations. Assuredly, if the poor professor had had any flesh to lose he would have withered away to a shadow. But this state of things was before long to come to an end. On the 12th, Ben Zoof, who was hanging about outside the great hall of the cavern, heard the professor inside utter a loud cry. Hurrying in to ascertain the cause, he found Rosette in a state of perfect frenzy, in which ecstasy and rage seemed to be struggling for the predominance. “Eureka! Eureka!” yelled the excited astronomer. “What, in the name of peace, do you mean?” bawled Ben Zoof, in open-mouthed amazement. “Eureka!” again shrieked the little man. “How? What? Where?” roared the bewildered orderly. “Eureka! I say,” repeated Rosette; “and if you don’t understand me, you may go to the devil!” Without availing himself of this polite invitation, Ben Zoof betook himself to his master. “Something has happened to the professor,” he said; “he is rushing about like a madman, screeching and yelling ‘Eureka!’” “Eureka?” exclaimed Servadac. “That means he has made a discovery;” and, full of anxiety, he hurried off to meet the professor. But, however great was his desire to ascertain what this discovery implied, his curiosity was not yet destined to be gratified. The professor kept muttering in incoherent phrases: “Rascal! he shall pay for it yet. I will be even with him! Cheat! Thrown me out!” But he did not vouchsafe any reply to Servadac’s inquiries, and withdrew to his study.
