Thus, only to speak of the planets, the people must be burnt up in some and frozen in others according as they are a long or short distance from the sun." "I regret," answered Michel Ardan, "not to know my honourable opponent personally.

His objection has its value, but I think it may be combated with some success, like all those of which the habitability of worlds has been the object.

If I were a physician I should say that if there were less caloric put in motion in the planets nearest to the sun, and more, on the contrary, in the distant planets, this simple phenomenon would suffice to equalise the heat and render the temperature of these worlds bearable to beings organised like we are.

If I were a naturalist I should tell him, after many illustrious _savants_, that Nature furnishes us on earth with examples of animals living in very different conditions of habitability; that fish breathe in a medium mortal to the other animals; that amphibians have a double existence difficult to explain; that certain inhabitants of the sea live in the greatest depths, and support there, without being crushed, pressures of fifty or sixty atmospheres; that some aquatic insects, insensible to the temperature, are met with at the same time in springs of boiling water and in the frozen plains of the Polar Ocean--in short, there are in nature many means of action, often incomprehensible, but no less real.
If I were a chemist I should say that aerolites--bodies evidently formed away from our terrestrial globe--have when analysed, revealed indisputable traces of carbon, a substance that owes its origin solely to organised beings, and which, according to Reichenbach's experiments, must necessarily have been 'animalised.' Lastly, if I were a theologian I should say that Divine Redemption, according to St.Paul, seems applicable not only to the earth but to all the celestial bodies.

But I am neither a theologian, chemist, naturalist, nor natural philosopher.
So, in my perfect ignorance of the great laws that rule the universe, I can only answer, 'I do not know if the heavenly bodies are inhabited, and, as I do not know, I am going to see!'" Did the adversary of Michel Ardan's theories hazard any further arguments?
It is impossible to say, for the frantic cries of the crowd would have prevented any opinion from being promulgated.
