IN WHICH DOCTOR OX REVEALS HIMSELF AS A PHYSIOLOGIST OF THE FIRST RANK, AND AS AN AUDACIOUS EXPERIMENTALIST.

Who, then, was this personage, known by the singular name of Doctor Ox?

An original character for certain, but at the same time a bold savant, a physiologist, whose works were known and highly estimated throughout learned Europe, a happy rival of the Davys, the Daltons, the Bostocks, the Menzies, the Godwins, the Vierordts--of all those noble minds who have placed physiology among the highest of modern sciences.

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.

The doctor, who was an able chemist as well as an ingenious physiologist, knew how to obtain this gas in great quantity and of good quality, not by using manganate of soda, according to the method of M. TessiÉ du Motay, but by the direct decomposition of slightly acidulated water, by means of a battery made of new elements, invented by himself. Thus there were no costly materials, no platinum, no retorts, no combustibles, no delicate machinery to produce the two gases separately. An electric current was sent through large basins full of water, and the liquid was decomposed into its two constituent parts, oxygen and hydrogen. The oxygen passed off at one end; the hydrogen, of double the volume of its late associate, at the other. As a necessary precaution, they were collected in separate reservoirs, for their mixture would have produced a frightful explosion if it had become ignited. Thence the pipes were to convey them separately to the various burners, which would be so placed as to prevent all chance of explosion. Thus a remarkably brilliant flame would be obtained, whose light would rival the electric light, which, as everybody knows, is, according to Cassellmann's experiments, equal to that of eleven hundred and seventy-one wax candles,--not one more, nor one less.

It was certain that the town of Quiquendone would, by this liberal contrivance, gain a splendid lighting; but Doctor Ox and his assistant took little account of this, as will be seen in the sequel.

The day after that on which Commissary Passauf had made his noisy entrance into the burgomaster's parlour, GÉdÉon YgÈne and Doctor Ox were talking in the laboratory which both occupied in common, on the ground-floor of the principal building of the gas-works.

"Well, YgÈne, well," cried the doctor, rubbing his hands. "You saw, at my reception yesterday, the cool-bloodedness of these worthy Quiquendonians. For animation they are midway between sponges and coral! You saw them disputing and irritating each other by voice and gesture? They are already metamorphosed, morally and physically! And this is only the beginning. Wait till we treat them to a big dose!"

"Indeed, master," replied YgÈne, scratching his sharp nose with the end of his forefinger, "the experiment begins well, and if I had not prudently closed the supply-tap, I know not what would have happened."

"You heard Schut, the advocate, and Custos, the doctor?" resumed Doctor Ox. "The phrase was by no means ill-natured in itself, but, in the mouth of a Quiquendonian, it is worth all the insults which the Homeric heroes hurled at each other before drawing their swords, Ah, these Flemings! You'll see what we shall do some day!"

"We shall make them ungrateful," replied YgÈne, in the tone of a man who esteems the human race at its just worth.

"Bah!" said the doctor; "what matters it whether they think well or ill of us, so long as our experiment succeeds?"

"Besides," returned the assistant, smiling with a malicious expression, "is it not to be feared that, in producing such an excitement in their respiratory organs, we shall somewhat injure the lungs of these good people of Quiquendone?"

"So much the worse for them! It is in the interests of science. What would you say if the dogs or frogs refused to lend themselves to the experiments of vivisection?"
