the Earth is a fact proved by observation; clouds are far less numerous, the atmosphere is much dryer, evaporation and condensation take place with greater rapidity, and the polar snows show variations, depending upon the season, much more extensive than those which take place upon the Earth. Again, the planet Venus, younger than the Earth, is surrounded by an immense atmosphere, constantly filled with clouds. As for the large planet Jupiter, we can only make out, as it were, an immense accumulation of vapors. Thus, the four worlds of which we know the most, confirm, each in its own way, the theory of a secular decrease in the amount of the Earth’s water.

“I am very happy to say in this connection that the theory of a general levelling process, maintained by my learned colleague, is confirmed by the present condition of the planet Mars. That eminent geologist told us a few moments ago, that, owing to the continuous action of rivers, plains almost horizontal would constitute the final form of the Earth’s surface. That is what has already happened in the case of Mars. The beaches near the sea are so flat that they are easily and frequently inundated, as everyone knows. From season to season hundreds of thousands of square kilometers are alternately exposed or covered by a thin layer of water. This is notably the case on the western shores of the Kaiser sea. On the Moon this levelling process has not taken place. There was not time enough for it; before its consummation, the air, the wind and the water had vanished.

“It is then certain that, while the Earth is destined to undergo a process of levelling, as my eminent colleague has so clearly explained, it will at the same time gradually lose the water which it now possesses. To all appearances, the latter process is now going on more rapidly than the former. As the Earth loses its internal heat and becomes cold, crevasses will undoubtedly form, as in the case of the Moon. The complete extinction of terrestrial heat will result in contractions, in the formation of hollow spaces below the surface, and the contents of the ocean will flow into these hollows, without being changed into vapor, and will be either absorbed or combined with the metallic rocks, in the form of ferric hydrates. The amount of water will thus go on diminishing indefinitely, and finally totally disappear. Plants, deprived of their essential constituent, will become transformed, but must at last perish.

“The animal species will also become modified, but there will always be herbivora and carnivora, and the extinction of the former will involve, inevitably, that of the latter; and at last, the human race itself, notwithstanding its power of adaption, will die of hunger and of thirst, on the bosom of a dried-up world.

“I conclude, therefore, gentlemen, that the end of the world will not be brought about by a new deluge, but by the loss of its water. Without water terrestrial life is impossible; water constitutes the chief constituent of every living thing. It is present in the human body in the enormous proportion of seventy percent. Without it, neither plants nor animals can exist. Either as a liquid, or in a state of vapor, it is the condition of life. Its suppression would be the death-warrant of humanity, and this death-warrant nature will serve upon us a dozen million years hence. I will add that this will take place before the completion of the erosion explained by the president of the geological society of France; for he, himself, was careful to note that the period of 4,000,000 years was dependent upon the hypothesis that the causes now in operation continued to act as they do today; and, furthermore, he, himself, admits that the manifestations of internal energy cannot immediately cease. Upheavals, at various points, will occur for a long period, and the growth of the land area from such causes as the formation of deltas, and volcanic and coral islands, will still go on for some time. The period which he indicated, therefore, represents only the minimum.”

Such was the address of the permanent secretary of the academy of meteorology. The audience had listened with the deepest attention to both speakers, and it was evident, from its bearing, that it was fully reassured concerning the fate of the world; it seemed even to have altogether forgotten the existence of the comet.

“The president of the physical society of France has the floor.”

At this invitation, a young woman, elegantly dressed in the most perfect taste, ascended the tribune.

“My two learned colleagues,” she began, without further preamble, “are both right; for, on the one hand, it is impossible to deny that meteorological agents, with the assistance of gravity, are working insensibly to level the world, whose crust is ever thickening and solidifying; and, on the other hand, the amount of water on the surface of our planet is decreasing from century to century. These two facts may be considered as scientifically established. But, gentlemen, it does not seem to me that the end of the world will be due to either the submergence of the continents, or to an insufficient supply of water for plant and animal life.”

This new declaration, this announcement of a third hypothesis, produced in the audience an astonishment bordering upon stupor.

“Nor do I believe,” the graceful orator hastened to add, “that the final catastrophe can be set down to the comet, for I agree with my two eminent predecessors, that worlds do not die by accident, but of old age.

“Yes, doubtless, gentlemen,” she continued, “the water will grow less, and, perhaps, in the end totally disappear; yet, it is not this lack of water which in itself will bring about the end of things, but its climatic consequences. The decrease in the amount of aqueous vapor in the atmosphere will lead to a general lowering of the temperature, and humanity will perish with cold.

“I need inform no one here that the
