Five Weeks in a Balloon

"Such, gentlemen, is my secret. It is simple, and, like most simple things, it cannot fail to succeed.

The dilation and contraction of the gas in the balloon is my means of locomotion, which calls for neither cumbersome wings, nor any other mechanical motor.

A calorifere to produce the changes of temperature, and a cylinder to generate the heat, are neither inconvenient nor heavy.

I think, therefore, that I have combined all the elements of success." Jules Verne's classic "Five Weeks in a Balloon" originally published in 1863.

A true literary gem.
