The result is ghastly. The lecturer steps up on to the platform alone and unaccompanied. There is a feeble ripple of applause; he makes his miserable bow and explains with as much enthusiasm as he can who he is. The atmosphere of the thing is so cold that an 'Arctic expedition isn't in it with it. I found also the further difficulty that in the absence of the chairman very often the audience, or a large part of it, doesn't know who the lecturer is. On many occasions I received on appearing a wild burst of applause under the impression that I was somebody else. I have been mistaken in this way for Mr. Briand, then Prime Minister of France, for Charlie Chaplin, for Mrs. Asquith,--but stop, I may get into a libel suit. All I mean is that without a chairman "we celebrities" get terribly mixed up together. To one experience of my tour as a lecturer I shall always be able to look back with satisfaction. I nearly had the pleasure of killing a man with laughing: and this in the most literal sense. American lecturers have often dreamed of doing this. I nearly did it. The man in question was a comfortable apoplectic-looking man with the kind of merry rubicund face that is seen in countries where they don't have prohibition. He was seated near the back of the hall and was laughing uproariously. All of a sudden I realised that something was happening. The man had collapsed sideways on to the floor; a little group of men gathered about him; they lifted him up and I could see them carrying him out, a silent and inert mass. As in duty bound I went right on with my lecture. But my heart beat high with satisfaction. I was sure that I had killed him. The reader may judge how high these hopes rose when a moment or two later a note was handed to the chairman who then asked me to pause for a moment in my lecture and stood up and asked, "Is there a doctor in the audience?" A doctor rose and silently went out. The lecture continued; but there was no more laughter; my aim had now become to kill another of them and they knew it. They were aware that if they started laughing they might die. In a few minutes a second note was handed to the chairman. He announced very gravely, "A second doctor is wanted." The lecture went on in deeper silence than ever. All the audience were waiting for a third announcement. It came. A new message was handed to the chairman. He rose and said, "If Mr. Murchison, the undertaker, is in the audience, will he kindly step outside." That man, I regret to say, got well. Disappointing though it is to read it, he recovered. I sent back next morning from London a telegram of enquiry (I did it in reality so as to have a proper proof of his death) and received the answer, "Patient doing well; is sitting up in bed and reading Lord Haldane's Relativity; no danger of relapse."
