"A strange animal was bounding along within a cable's length from the ship."

"It's an enormous bear," said one.

"It's the beast of Gévaudan!"

"It's the lion of the Apocalypse!"

Shandon ran to his cabin to get a gun which he kept always loaded; the doctor seized his arms, and made ready to fire at the beast, which by its size, recalled antediluvian monsters.

It drew near with long leaps; Shandon and the doctor fired at the same time, and suddenly the report of the pieces agitated the air and produced an unlooked-for effect.

The doctor gazed attentively, and could not help bursting out laughing. "It's refraction!" said he.

"Refraction!" cried Shandon.

But a terrible cry from the crew interrupted them.

"The dog!" shouted Clifton.
