Had they been outside, the effect would have been precisely the same.

No rush of air, no jarring sensation would betray the slightest movement.

But for the sight of the Moon gradually growing larger above them, and of the Earth gradually growing smaller beneath them, they could safely swear that they were fast anchored in an ocean of deathlike immobility.
Towards the morning of next day (December 3), they were awakened by a joyful, but quite unexpected sound.
"Cock-a-doodle! doo!" accompanied by a decided flapping of wings.
The Frenchman, on his feet in one instant and on the top of the ladder in another, attempted to shut the lid of a half open box, speaking in an angry but suppressed voice: "Stop this hullabaloo, won't you?
Do you want me to fail in my great combination!" "Hello ?" cried Barbican and M'Nicholl, starting up and rubbing their eyes.

"Seems to me I heard the crowing of a cock," observed the Captain.
"I never thought your ears could be so easily deceived, Captain," cried Ardan, quickly, "Let us try it again," and, flapping his ribs with his arms, he gave vent to a crow so loud and natural that the lustiest chanticleer that ever saluted the orb of day might be proud of it.
The Captain roared right out, and even Barbican snickered, but as they saw that their companion evidently wanted to conceal something, they immediately assumed straight faces and pretended to think no more about the matter.
"Barbican," said Ardan, coming down the ladder and evidently anxious to change the conversation, "have you any idea of what I was thinking about all night ?" "Not the slightest." "I was thinking of the promptness of the reply you received last year from the authorities of Cambridge University, when you asked them about the feasibility of sending a bullet to the Moon.

You know very well by this time what a perfect ignoramus I am in Mathematics.

I own I have been often puzzled when thinking on what grounds they could form such a positive opinion, in a case where I am certain that the calculation must be an exceedingly delicate matter." "The feasibility, you mean to say," replied Barbican, "not exactly of sending a bullet to the Moon, but of sending it to the neutral point between the Earth and the Moon, which lies at about nine-tenths of the journey, where the two attractions counteract each other.
