"The celebrated Arago says that he who, outside of pure mathematics, uses the word impossible, lacks prudence," said the Professor. "Here he comes!" cried Tom Seddon, as a bull of prodigious size and savage ferocity bounded into the arena, and after moving around and wildly glaring at the assembled multitude, finally halted within a few paces of the seats occupied by Toney and the Professor. The enraged animal was pawing the earth with his foot, when one of the combatants advanced towards him, brandishing a dart. The bull elevated his head and surveyed him with an indignant look. The man poised his missile and was about to hurl it when, in the Castilian language, from the mouth of the angry animal come forth the words,-- "Hold, villain! hold!" The man dropped his dart and instantly fled. On the seats in proximity to the Professor there were great commotion and alarm, while from those afar off there were loud cries of derision at the cowardice exhibited by the combatant who had fled. Several men now advanced on foot, and the horsemen followed, with the four buzzards in the rear, flapping their wings. They surrounded the bull, and each footman brandished his dart, while the horsemen poised their lances. The animal regarded them with a ferocious aspect, and, as they were about to attack him with their weapons, a hoarse voice was heard issuing from his throat, and exclaiming,-- "Stand back! ye bloody villains, forbear!" The men recoiled in horror, and, dropping their weapons, fled with precipitation, exclaiming, "El diablo! el diablo!" The buzzards hurried over the barricades followed by the footmen, who threw themselves among the spectators, crying out, "El diablo! el diablo!--it is the devil! it is the devil!" The horsemen galloped frantically around, and finally fled through a gate, which was instantly closed and barred. "El diablo! el diablo!" was shouted by hundreds of voices. "It is Satan! it is Satan!" exclaimed several priests, who sat near the Professor, as the bull, after running around, stood still and glared at them with fiery eyes. "I am Beelzebub!" roared the bull. With loud cries of "Satan!" "Beelzebub!" "the devil!" the priests and the people leaped from their seats, and, tumbling over each other, rolled out of the amphitheater into the open air. Along the banks of the Rimac, men, women, and children were flying in terror, with loud cries of "El diablo! el diablo!" "Where is Moses?" asked the Professor, as with Toney and Tom he sat in the deserted amphitheater. "He and Wiggins have gone with the crowd," said Toney. "The bull will have to perform before empty benches," said the Professor. "That animal has created more commotion than any of the Pope's bulls in the Dark Ages," said Toney. "He is equal to Apis, the sacred bull of the Egyptians," said the Professor, as they arose from their seats and left the amphitheater. CHAPTER XLIV.
