The night was spent in these vain attempts. Her fever increased. Next day she was delirious and kept on muttering letters and figures which were never the same. For a week, her life was despaired of. She suffered horribly with her head and wore herself out scribbling lines on her bed clothes. When she became convalescent and had recovered her consciousness, we avoided the subject and did not refer to it for some time. But I felt that she never ceased to think of it and that she continued to seek the formula. At last, one day, she said with tears in her eyes: "I have given up all hopes, dear. I repeated that formula a hundred times after I had learnt it; and I felt sure of my memory. But not a single recollection of it remains. It must have been when Velmot was clutching my throat. Everything grew dark, suddenly. I know now that I shall never remember." * * * * * She never did remember. The exhibitions at the Yard were not resumed. The miraculous visions did not reappear. And yet what investigations were pursued! How many companies have been promoted which attempted to exploit the lost secret! But all in vain: the screen remained lifeless and empty, like a blind man's eyes. To Bérangère and me it would have meant a sorrow incessantly renewed, if love had not brought us peace and consolation in all things. The authorities, who showed themselves fairly easy-going, I think, in this case, never found any traces of the woman who bore the name of Massignac. I was dispatched on a mission to the Far East. I sent out for her; and we were married without attracting attention. We often speak of Noël Dorgeroux's great secret; and if Bérangère's lovely eyes become clouded with sadness: "Certainly," I say, "the lost secret was a wonderful thing. There was never anything more thrilling than the Meudon pictures; and those which we had a right to expect might have opened up horizons which we are not able to conceive. But are you quite sure that we ought to regret them? Does a knowledge of the past and the future spell happiness for mankind? Is it not rather an essential law of our equilibrium that we should be obliged to live within the narrow confines of the present and to see before or behind us no more than lights which are still just glimmering and lights which are being faintly kindled? Our knowledge is adjusted to our strength; and it is not good to learn and to decipher too quickly truths to which we have not had time to adapt our existence and riddles which we do not yet deserve to know." Benjamin Prévotelle made no attempt to conceal his disappointment. I keep up a regular correspondence with him. In every letter that I receive from this great scientist I anticipate his anxious question: "Does she remember? May we hope?" Alas, my answers leave him no illusions: "Bérangère remembers nothing. You must not hope."
