His next memoir, sent to the Royal Society, December 31, 1851, is 'on the employment of the Induced Magnetoelectro Current as a test and measure of magnetic forces. He forms rectangles and rings, and by ingenious and simple devices collects the opposed currents which are developed in them by rotation across the terrestrial lines of magnetic force.

Neither metal, saltpetre, nor coal can be wanting in the bowels of the moon. Besides, in order to return you have only the lunar attraction to conquer, and you will only have 8,000 leagues to go so as to fall on the terrestrial globe by the simple laws of weight." "That is enough," said Michel, getting animated. "Let us hear no more about returning.

Scarcely a particle of air escaped, and the operation succeeded so well that later on Barbicane did not fear to get rid of all the useless rubbish that encumbered the vehicle in the same way. On the 4th of December, at 5 a.m. by terrestrial reckoning, the travellers awoke, having been fifty-four hours on their journey.

No debris, no atmosphere, no vapor, no single atom of material substance the first time in Terrestrial experience that an absolute vacuum had ever been attained! Stubbornly contesting every foot of way lost, the Nevian fog retreated before the violet sphere of nothingness.

In refusing a miracle, in dealing so hard a blow to that house, God had doubtless had His reasons, and he, the Cardinal, one of God's ministers, one of the high dignitaries of His terrestrial court, was in duty bound to bow to it.

"Well," said Michel, "that is a way of ending the earth which will greatly simplify things." "And if the earth fell upon the sun?" asked Nicholl. "According to calculation," replied Barbicane, "the fall would develop a heat equal to that produced by 16,000 globes of coal, each equal in bulk to our terrestrial globe."

Her face was hidden, and I wondered whether it were grief or gratitude that raised her hands and drew her eyes to the altar, where no living prayer joined her marble invocation. I followed my guide down the tribune steps, impatient to see what mystic version of such terrestrial graces the ingenious artist had found the Cavaliere was master of such arts.

Thus he accounted for the exceptional volume of water by the motion of rivers flowing down from the end of the pear. One step farther in the realms of fancy, and he indulged in a dream that this centre and apex of the earth's surface, with its mighty rivers, could be no other than the terrestrial paradise.

But by the by why does not such extreme heat cook us all up like so many beefsteaks?" "For two very good and sufficient reasons," answered Barbican. "In the first place, the terrestrial atmosphere absorbs the 4/10 of the solar heat. In the second, the quantity of solar heat intercepted by the Earth is only about the two billionth part of all that is radiated."

Notwithstanding the striking similarity of these creatures to their terrestrial counterparts that existed on earth during its corresponding period, there were some interesting modifications.
