"We should all fall into the sun!"

"Fall into the sun!" repeated Bell with surprise.

"Yes. If this motion were to stop, the earth would fall into the sun in sixty-four days and a half."

"A fall of sixty-four days!" said Johnson.

"No more nor less," answered the doctor; "for it would have to fall a distance of thirty-eight millions of leagues."

"What is the weight of the earth?" asked Altamont.

"It is five thousand eight hundred and ninety-one quadrillions of tons."

"Good!" said Johnson; "those numbers have no meaning."
