"For example?" said the Doctor. "Of course, we don't doubt your word; but when a man makes a statement based upon personal observation it is profitable to ask him what his precise experience has been, merely for the purpose of adding to our own knowledge." "Well," said the Idiot, "the first instance that I can recall is that of a Wagner opera and its effects upon me. For a number of years I suffered a great deal from insomnia. I could not get two hours of consecutive sleep, and the effect of my sufferings was to make me nervous and irritable. Suddenly somebody presented me with a couple of tickets for a performance of 'Parsifal,' and I went. It began at five o'clock in the afternoon. For twenty minutes all went serenely, and then the music began to work. I fell into a deep and refreshing slumber. The intermission came, and still I slept on. Everybody else went home, dressed for the evening part of the performance, had their dinner, and returned. Still I slept, and continued so to do until midnight, when one of the gentlemanly ushers came and waked me up, and told me that the performance was over. I rubbed my eyes, and looked about me. It was true--the great auditorium was empty, and was gradually darkening. I put on my hat and walked out refreshed, having slept from five-twenty until twelve, or six hours and forty minutes straight. That was one instance. Two weeks later I went again, this time to hear 'Götterdämmerung.' The results were the same, only the effect was instantaneous. The curtain had hardly risen before I retired to the little ante-room of the box our party occupied and dozed off into a fathomless sleep. I didn't wake up this time until nine o'clock the next day, the rest of the party having gone off without awakening me as a sort of joke. Clearly Wagner, according to my way of thinking, then, deserves to rank among the most effective narcotics known to modern science. I have tried all sorts of other things--sulfonal, trionel, bromide powders, and all the rest, and not one of them produced anything like the soporific results that two doses of Wagner brought about in one instant. And, best of all, there was no reaction: no splitting headache or shaky hand the next day, but just the calm, quiet, contented feeling that goes with the sense of having got completely rested up." "You run a dreadful risk, however," said the Doctor, with a sarcastic smile. "The Wagner habit is a terrible thing to acquire, Mr. Idiot."
