world, but it is beyond this glamour and this vision, beyond these ‘chases in Arras, dreams in a career,’ beyond them all as beyond a veil. I do not know whether any human being has ever lifted that veil; but I do know, Clarke, that you and I shall see it lifted this very night from before another’s eyes. You may think this all strange nonsense; it may be strange, but it is true, and the ancients knew what lifting the veil means. They called it seeing the god Pan.” Clarke shivered; the white mist gathering over the river was chilly. “It is wonderful indeed,” he said. “We are standing on the brink of a strange world, Raymond, if what you say is true. I suppose the knife is absolutely necessary?” “Yes; a slight lesion in the grey matter, that is all; a trifling rearrangement of certain cells, a microscopical alteration that would escape the attention of ninety-nine brain specialists out of a hundred. I don’t want to bother you with ‘shop,’ Clarke; I might give you a mass of technical detail which would sound very imposing, and would leave you as enlightened as you are now. But I suppose you have read, casually, in out-of-the-way corners of your paper, that immense strides have been made recently in the physiology of the brain. I saw a paragraph the other day about Digby’s theory, and Browne Faber’s discoveries. Theories and discoveries! Where they are standing now, I stood fifteen years ago, and I need not tell you that I have not been standing still for the last fifteen years. It will be enough if I say that five years ago I made the discovery that I alluded to when I said that ten years ago I reached the goal. After years of labour, after years of toiling and groping in the dark, after days and nights of disappointments and sometimes of despair, in which I used now and then to tremble and grow cold with the thought that perhaps there were others seeking for what I sought, at last, after so long, a pang of sudden joy thrilled my soul, and I knew the long journey was at an end. By what seemed then and still seems a chance, the suggestion of a moment’s idle thought followed up upon familiar lines and paths that I had tracked a hundred times already, the great truth burst upon me, and I saw, mapped out in lines of sight, a whole world, a sphere unknown; continents and islands, and great oceans in which no ship has sailed (to my belief) since a Man first lifted up his eyes and beheld the sun, and the stars of heaven, and the quiet earth beneath. You will think this all high-flown language, Clarke, but it is hard to be literal. And yet; I do not know whether what I am hinting at cannot be set forth in plain
