"I think that if you knew more about the facts you might be less positive in your opinion," said I. Summerlee took his pipe from his mouth and fixed me with a stony stare. "Pray what do you mean, sir, by that somewhat impertinent observation?" "I mean that when I was leaving the office the news editor told me that a telegram had come in confirming the general illness of the Sumatra natives, and adding that the lights had not been lit in the Straits of Sunda." "Really, there should be some limits to human folly!" cried Summerlee in a positive fury. "Is it possible that you do not realize that ether, if for a moment we adopt Challenger's preposterous supposition, is a universal substance which is the same here as at the other side of the world? Do you for an instant suppose that there is an English ether and a Sumatran ether? Perhaps you imagine that the ether of Kent is in some way superior to the ether of Surrey, through which this train is now bearing us. There really are no bounds to the credulity and ignorance of the average layman. Is it conceivable that the ether in Sumatra should be so deadly as to cause total insensibility at the very time when the ether here has had no appreciable effect upon us whatever? Personally, I can truly say that I never felt stronger in body or better balanced in mind in my life." "That may be. I don't profess to be a scientific man," said I, "though I have heard somewhere that the science of one generation is usually the fallacy of the next. But it does not take much common sense to see that, as we seem to know so little about ether, it might be affected by some local conditions in various parts of the world and might show an effect over there which would only develop later with us." "With 'might' and 'may' you can prove anything," cried Summerlee furiously. "Pigs may fly. Yes, sir, pigs _may_ fly--but they don't. It is not worth arguing with you. Challenger has filled you with his nonsense and you are both incapable of reason. I had as soon lay arguments before those railway cushions." "I must say, Professor Summerlee, that your manners do not seem to have improved since I last had the pleasure of meeting you," said Lord John severely. "You lordlings are not accustomed to hear the truth," Summerlee answered with a bitter smile. "It comes as a bit of a shock, does it not, when someone makes you realize that your title leaves you none the less a very ignorant man?" "Upon my word, sir," said Lord John, very stern and rigid, "if you were a younger man you would not dare to speak to me in so offensive a fashion." Summerlee thrust out his chin, with its little wagging tuft of goatee beard. "I would have you know, sir, that, young or old, there has never been a time in my life when I was afraid to speak my mind to an ignorant coxcomb--yes, sir, an ignorant coxcomb, if you had as many titles as slaves could invent and fools could adopt."
