“I understand no more,” said Michel.
“It is a very simple calculation,” said Barbicane.
“Not as simple as I am,” retorted Michel.
“That means, that when our projectile reached the limits of the terrestrial atmosphere it had already lost one-third of its initiatory speed.”
“As much as that?”
“Yes, my friend; merely by friction against the atmospheric strata. You understand that the faster it goes the more resistance it meets with from the air.”
“That I admit,” answered Michel; “and I understand it, although your x’s and zero’s, and algebraic formula, are rattling in my head like nails in a bag.”
“First effects of algebra,” replied Barbicane; “and now, to finish, we are going to prove the given number of these different expressions, that is, work out their value.”
“Finish me!” replied Michel.
Barbicane took the paper, and began to make his calculations with great rapidity. Nicholl looked over and greedily read the work as it proceeded.
