A time that seemed to me inexorably long, but which, as I found afterwards, could only have occupied a few seconds, elapsed in this preliminary state, which, however powerless, was not without a vague luxurious sense of delight. And then suddenly came pain,--pain, that in rapid gradations passed into a rending agony. Every bone, sinew, nerve, fibre of the body, seemed as if wrenched open, and as if some hitherto unconjectured Presence in the vital organization were forcing itself to light with all the pangs of travail. The veins seemed swollen to bursting, the heart labouring to maintain its action by fierce spasms. I feel in this description how language fails me. Enough that the anguish I then endured surpassed all that I have ever experienced of physical pain. This dreadful interval subsided as suddenly as it had commenced. I felt as if a something undefinable by any name had rushed from me, and in that rush that a struggle was over. I was sensible of the passive bliss which attends the release from torture, and then there grew on me a wonderful calm, and, in that calm, a consciousness of some lofty intelligence immeasurably beyond that which human memory gathers from earthly knowledge. I saw before me the still rigid form of Margrave, and my sight seemed, with ease, to penetrate through its covering of flesh, and to survey the mechanism of the whole interior being. "View that tenement of clay which now seems so fair, as it was when I last beheld it, three years ago, in the house of Haroun of Aleppo!" I looked, and gradually, and as shade after shade falls on the mountain side, while the clouds gather, and the sun vanishes at last, so the form and face on which I looked changed from exuberant youth into infirm old age,--the discoloured wrinkled skin, the bleared dim eye, the flaccid muscles, the brittle sapless bones. Nor was the change that of age alone; the expression of the countenance had passed into gloomy discontent, and in every furrow a passion or a vice had sown the seeds of grief. And the brain now opened on my sight, with all its labyrinth of cells. I seemed to have the clew to every winding in the maze.
