“On the contrary,” continued Barbicane.

“One moment,” said Michel, interrupting his grave companion.

“What do you want?”

“I ask to be allowed to continue the explanation.”

“And why?”

“To prove that I understand.”

“Get along with you,” said Barbicane, smiling.

“On the contrary,” said Michel, imitating the tone and gestures of the president, “on the contrary, when the visible face of the moon is lit by the sun, it is because the moon is full, that is to say, opposite the sun with regard to the earth. The distance separating it from the radiant orb is then increased in round numbers to 400,000 miles, and the heat which she receives must be a little less.”

“Very well said!” exclaimed Barbicane. “Do you know, Michel, that, for an amateur, you are intelligent.”

“Yes,” replied Michel coolly, “we are all so on the Boulevard des Italiens.”
