After allowing for a certain margin of miscalculation, the main fact remained undeniable; and the necessary inference that Lieutenant Procope drew from the round of the earth being completed in 1 ,400 miles, was that the earth's diameter had been reduced by about fifteen sixteenths of its length.

"If that be so," observed the count, "it accounts for some of the strange phenomena we witness. If our world has become so insignificant a spheroid, not only has its gravity diminished, but its rotary speed has been accelerated; and this affords an adequate explanation of our days and nights being thus curtailed. But how about the new orbit in which we are moving?"

He paused and pondered, and then looked at Procope as though awaiting from him some further elucidation of the difficulty. The lieutenant hesitated. When, in a few moments, he began to speak, Servadac smiled intelligently, anticipating the answer he was about to hear.

"My conjecture is," said Procope, "that a fragment of considerable magnitude has been detached from the earth; that it has carried with it an envelope of the earth's atmosphere, and that it is now traveling through the solar system in an orbit that does not correspond at all with the proper orbit of the earth."
