After a perfect swoon, which lasted some minutes, the captain, recovering first, soon collected his scattered senses. Although he had breakfasted only two hours before, he felt a gnawing hunger, as if he had not eaten anything for several days. Everything about him, stomach and brain, were overexcited to the highest degree. He got up and demanded from Michel a supplementary repast. Michel, utterly done up, did not answer. Nicholl then tried to prepare some tea destined to help the absorption of a dozen sandwiches. He first tried to get some fire, and struck a match sharply. What was his surprise to see the sulphur shine with so extraordinary a brilliancy as to be almost unbearable to the eye. From the gas-burner which he lit rose a flame equal to a jet of electric light. A revelation dawned on Nicholl's mind. That intensity of light, the physiological troubles which had arisen in him, the overexcitement of all his moral and quarrelsome faculties,—he understood all. "The oxygen!" he exclaimed. And leaning over the air apparatus, he saw that the tap was allowing the scentless colourless gas to escape freely, life-giving, but in its pure state producing the gravest disorders in the system. Michel had blunderingly opened the tap of the apparatus to the full. Illustration: "THE OXYGEN!" HE EXCLAIMED. Nicholl hastened to stop the escape of oxygen with which the atmosphere was saturated, which would have been the death of the travellers, not by suffocation, but by combustion. An hour later, the air less charged with it restored the lungs to their normal condition. By degrees the three friends recovered from their intoxication; but they were obliged to sleep themselves sober over their oxygen as a drunkard does over his wine. When Michel learnt his share of the responsibility of this incident, he was not much disconcerted. This unexpected drunkenness broke the monotony of the journey. Many foolish things had been said while under its influence, but also quickly forgotten. "And then," added the merry Frenchman, "I am not sorry to have tasted a little of this heady gas. Do you know, my friends, that a curious establishment might be founded with rooms of oxygen, where people whose system is weakened could for a few hours live a more active life. Fancy parties where the room was saturated with this heroic fluid, theatres where it should be kept at high pressure; what passion in the souls of the actors and spectators! what fire, what enthusiasm! And if, instead of an assembly only a whole people could be saturated, what activity in its functions, what a supplement to life it would derive. From an exhausted nation they might make a great and strong one, and I know more than one state in old Europe which ought to put itself under the regime of oxygen for the sake of its health!" Michel spoke with so much animation that one might have fancied that the tap was still too open. But a few words from Barbicane soon scattered his enthusiasm.
