doors are there in the walls, dome and roof of the House of the Skull?" One thing I insisted on, before I went "back" again. I didn't go for the name of Dean Hale, if Hale were a murderer. "Then we'll call you Everyman," said Doctor A, "since every man, in this same situation, would bring us about the same story, if his proper past lives were chosen. You are Adam Everyman. Now let's get on with the next excursion." CHAPTER IV Faster Than Sound I knew that the eleven scientists who traveled with me, collaborated to build, through the mediation of the cyclotron, the House of the Skull; that it was an enlargement of my own skull. The "doors" were segments, the "keys" symbols of location and identification. The Lab had seemingly proved reincarnation. Could it have been coincidence? No, I believed I had been Father Wulstan, was still Father Wulstan in spirit, though in this life I had now forgotten, I may have refused to be a minister again. I could understand my refusal in terms of reincarnation. I had once refused, or been compelled to refuse, to do everything required of a scientist. I had hidden a most important invention away. Now I must produce it, in accordance with the Law of Consequences, of Cause and Effect. The combined thought of the eleven colleagues of Doctor A, directed into the cyclotron, therein to assemble, by the power of thought, special hordes of electrons, could very well construct of them the Building of the Skull, which thus might not be a thought form at all—scientifically! I knew there were things in the invisible man knew, could not prove or delineate; modern experiments with nuclear fission was proving that, and this was somehow nuclear fission far in advance of modern science, according to Jan Rober. Thought could be registered. That fact had long been accepted. Mechanical means could register the weight and substance of thought. Everything that existed, even energy, and therefore thought, was composed of electrons. I was beginning to see the deep meaning behind The Lab. From my brain alone, the scientists could recover from the Invisible Records, more of world history than could be found in books. If men had existed through endless lives, man the individual had—and I was merely one. Each was an historical record himself. Thus The Lab seemed to have proved in its work with me. However, I did
