The most amusing incident was that which happened on the occasion of an experiment with radium. I had described to the sovereign, in the course of conversation, the wonderful discovery which our great _savant_, M. Currie, had just made, a discovery that was called upon to revolutionise science. The Shah was extremely interested by my story and repeatedly expressed a desire to be shown the precious magic stone. Professor Currie was informed accordingly, and, in spite of his stress of work, agreed to come to the Élysée Palace Hôtel and give an exhibition. As, however, complete darkness was needed for radium to be admired in all its brilliancy, I had with endless trouble persuaded the King of Kings to come down to one of the hotel cellars arranged for the purpose. At the appointed time, His Majesty and all his suite proceeded to the underground apartment in question. Professor Currie closed the door, switched off the electric light and uncovered his specimen of radium, when, suddenly, a shout of terror, resembling at one and the same time the roar of a bull and the yells of a man who is being murdered, rang out, followed by hundreds of similar cries. Amid general excitement and consternation, we flung ourselves upon the electric switches, turned on the lights and beheld a strange sight: in the midst of the prostrate Persians stood the Shah, his arms clinging to the neck of his howling grand vizier, his round pupils dilated to their rims, while he shouted at the top of his voice, in Persian: "Come away! Come away!" The switching on of the light calmed this mad anguish as though by magic. Realising the disappointment which he had caused M. Currie, he tried to offer him a decoration by way of compensation; but the austere man of science thought right to decline it. The instinctive dread of darkness and solitude was so keen in the Persian monarch that he required his bed-room to be filled during the night with light and sound. Accordingly, every evening, as soon as he had lain down and closed his eyes, the members of his suite gathered round his bed, lit all the candelabra and exchanged their impressions aloud, while young nobles of the court, relieving one another in pairs, conscientiously patted his arms and legs with little light, sharp, regular taps. The King of Kings imagined that he was in this way keeping death at a distance, if perchance it should take a fancy to visit him in his sleep, and the extraordinary thing is that he did sleep, notwithstanding all this massage, light and noise. 4.
