Doctor Ox was a man of medium size and height, aged—: but we cannot state his age, any more than his nationality. Besides, it matters little; let it suffice that he was a strange personage, impetuous and hot-blooded, a regular oddity out of one of Hoffmann’s volumes, and one who contrasted amusingly enough with the good people of Quiquendone. He had an imperturbable confidence both in himself and in his doctrines. Always smiling, walking with head erect and shoulders thrown back in a free and unconstrained manner, with a steady gaze, large open nostrils, a vast mouth which inhaled the air in liberal draughts, his appearance was far from unpleasing. He was full of animation, well proportioned in all parts of his bodily mechanism, with quicksilver in his veins, and a most elastic step. He could never stop still in one place, and relieved himself with impetuous words and a superabundance of gesticulations. Was Doctor Ox rich, then, that he should undertake to light a whole town at his expense? Probably, as he permitted himself to indulge in such extravagance,—and this is the only answer we can give to this indiscreet question. Doctor Ox had arrived at Quiquendone five months before, accompanied by his assistant, who answered to the name of Gédéon Ygène; a tall, dried-up, thin man, haughty, but not less vivacious than his master. And next, why had Doctor Ox made the proposition to light the town at his own expense? Why had he, of all the Flemings, selected the peaceable Quiquendonians, to endow their town with the benefits of an unheard-of system of lighting? Did he not, under this pretext, design to make some great physiological experiment by operating _in anima vili?_ In short, what was this original personage about to attempt? We know not, as Doctor Ox had no confidant except his assistant Ygène, who, moreover, obeyed him blindly. In appearance, at least, Doctor Ox had agreed to light the town, which had much need of it, “especially at night,” as Commissary Passauf wittily said. Works for producing a lighting gas had accordingly been established; the gasometers were ready for use, and the main pipes, running beneath the street pavements, would soon appear in the form of burners in the public edifices and the private houses of certain friends of progress. Van Tricasse and Niklausse, in their official capacity, and some other worthies, thought they ought to allow this modern light to be introduced into their dwellings. If the reader has not forgotten, it was said, during the long conversation of the counsellor and the burgomaster, that the lighting of the town was to be achieved, not by the combustion of common carburetted hydrogen, produced by distilling coal, but by the use of a more modern and twenty-fold more brilliant gas, oxyhydric gas, produced by mixing hydrogen and oxygen.
