They are different planes of matter. They cannot impinge upon one another. Come, Challenger, you could not defend such a proposition."
"My good Summerlee, this etheric poison is most certainly influenced by material agents. We see it in the methods and distribution of the outbreak. We should not A PRIORI have expected it, but it is undoubtedly a fact. Hence I am strongly of opinion that a gas like oxygen, which increases the vitality and the resisting power of the body, would be extremely likely to delay the action of what you have so happily named the daturon. It may be that I am mistaken, but I have every confidence in the correctness of my reasoning."
"Well," said Lord John, "if we've got to sit suckin' at those tubes like so many babies with their bottles, I'm not takin' any."
"There will be no need for that," Challenger answered. "We have made arrangements--it is to my wife that you chiefly owe it--that her boudoir shall be made as airtight as is practicable. With matting and varnished paper." "Good heavens, Challenger, you don't suppose you can keep out ether with varnished paper?"
"Really, my worthy friend, you are a trifle perverse in missing the point. It is not to keep out the ether that we have gone to such trouble. It is to keep in the oxygen. I trust that if we can ensure an atmosphere hyper-oxygenated to a certain point, we may be able to retain our senses. I had two tubes of the gas and you have brought me three more. It is not much, but it is something."
"How long will they last?"
"I have not an idea. We will not turn them on until our symptoms become unbearable. Then we shall dole the gas out as it is urgently needed. It may give us some hours, possibly even some days, on which we may look out upon a blasted world. Our own fate is delayed to that extent, and we will have the very singular experience, we five, of being, in all probability, the absolute rear guard of the human race upon its march into the unknown. Perhaps you will be kind enough now to give me a hand with the cylinders. It seems to me that the atmosphere already grows somewhat more oppressive."
The chamber which was destined to be the scene of our unforgettable experience was a charmingly feminine sitting-room, some fourteen or sixteen feet square. At the end of it, divided by a curtain of red velvet, was a small apartment which formed the Professor's dressing-room. This in turn opened into a large bedroom. The curtain was still hanging, but the boudoir and dressing-room could be taken as one chamber for the purposes of our experiment. One door and the window frame had been plastered round with varnished paper so as to be practically sealed. Above the other door, which opened on to the landing, there hung a fanlight which could be drawn by a cord when some ventilation became absolutely necessary. A large shrub in a tub stood in each corner.
"How to get rid of our excessive carbon dioxide without unduly wasting our oxygen is a delicate and vital question," said Challenger, looking round him after the five iron tubes had been laid side by side against the wall. "With longer time for preparation I could have brought the whole concentrated force of my intelligence to bear more fully upon the problem, but as it is we must do what we can. The shrubs will be of some small service. Two of the oxygen tubes are ready to be turned on at an instant's notice, so that we cannot be taken unawares. At the same time, it would be well not to go far from the room, as the crisis may be a sudden and urgent one."
There was a broad, low window opening out upon a balcony. The view beyond was the same as that which we had already admired from the study. Looking out, I could see no sign of disorder anywhere. There was a road curving down the side of the hill, under my very eyes. A cab from the station, one of those prehistoric survivals which are only to be found in our country villages, was toiling slowly up the hill.
