"Yes, the lecture if you like. That'll do to start with. No, I don't want anything, thanks. Tell me what you thought of the lecture." I began to say something, I hardly remember what, when, still with his eyes closed and twitching, he interrupted me. "All those silly charts--all those useless figures about the American Army--that's all waste of time. Making work for work's sake. I could have told him all that straight away." I remembered those groans in the obscurity of the lecture-room. I spoke quietly. "Is that what you were going to tell him when you--interrupted a little?" I had to wait for his reply. When it did come I hardly heard it, so low did he speak. "I know what you mean; but I can only tell you that if you'd been vivisected like that you'd have squirmed a bit too." I couldn't help thinking he had taken that lecture in a curiously personal sense, and I said so. "Vivisected?" I exclaimed. "I was vivisected, as you call it, just as much as you were--perhaps more in some ways. What on earth are you talking about? It's a general question. It's human functions and faculties at large he was vivisecting, not you or me. So," I concluded, "we were all vivisected alike, and when everybody's vivisected--you see----" I made a little gesture. Then he opened his eyes, and there was an expression in them that suddenly dried me up. It was an even more remarkable throw-back to a remembered and earlier manner than that I had witnessed earlier in the afternoon. In short, it was an expression of unconcealed contempt. "Q.E.D.," he said. "Finis, Explicit, and the Upper Fourth next Term. You'd have made a good schoolmaster.... I tell you that when I say 'I' and 'myself'"--he positively glared with irascibility and impatience--"I mean myself singly and specially, understand--the egregious and indestructible ego--and not merely just as much or as little as anybody else. Get that well into your head or I won't talk to you." Had he not been so visibly suffering I shouldn't have stood the tone of it for a moment, not even from him. And let me tell you at once the surmise that had already flashed through my brain. I am a dependable sort of person myself, one of the kind that nothing startlingly new is ever likely to happen to; but I was not so sure about his kind. Brains like his often fly off at queer tangents, and I wondered whether he had been reading too much of this current cant about "multiple personality" and had allowed it to run away with him. Every Tom, Dick and Harry seems to rush to that for an explanation of everything nowadays. I had already noticed, by the way, that one of the books that sprawled cover uppermost on his table was a book on the thyroid gland. But suddenly he seemed to guess at my thoughts. He spoke more quietly. Indeed he seemed to be fully aware of these outbreaks of his, and to be trying to resist them more and more strenuously as our conversation proceeded.
