ing Suzel to her lover, who hastened to wed her five or six years after these events.
And as for Madame Van Tricasse, she died ten years later, at the proper time, and the burgomaster married Mademoiselle Pelagie Van Tricasse, his cousin, under excellent conditions—for the happy mortal who should succeed him.
CHAPTER XVII
In which Doctor Ox's Theory is Explained
What, then, had this mysterious Doctor Ox done? Tried a fantastic experiment—nothing more.
After having laid down his gas pipes, he had saturated, first the public buildings, then the private dwellings, finally the streets of Quiquendone, with pure oxygen, without letting in the least atom of hydrogen.
This gas, tasteless and odorless, spread in generous quantity through the atmosphere, causes, when it is breathed, serious agitation to the human organism. One who lives in an air saturated with oxygen grows excited, frantic, burns!
You scarcely return to the ordinary atmosphere before you return to your usual state. For instance, the counselor and the burgomaster at the top of the belfry were themselves again, as the oxygen is kept, by its weight, in the lower strata of the air.
But one who lives under such conditions, breathing this gas which transforms the body physiologically as well as the soul, dies speedily, like a madman.
It was fortunate, then, for the Quiquendonians, that a providential explosion put an end to this dangerous experiment, and abolished Doctor Ox's gas works.
To conclude: Are virtue, courage, talent, wit, imagination, are all these qualities or faculties only a question of oxygen?
Such is Doctor Ox's theory; but we are not bound to accept it, and for ourselves we utterly reject it, in spite of the curious experiment of which the worthy old town of Quiquendone was the theater.
