“Very well--so far, then, we have nothing in this phenomenon which the human mind cannot conceive as possible; therefore intellectually we still remain masters of the phenomena; for it is only that which human thought cannot encompass which it need fear.” “Metallic,” he said, “and crystalline. And yet--why not? What are we but bags of skin filled with certain substances in solution and stretched over a supporting and mobile mechanism largely made up of lime? Out of that primeval jelly which Gregory * calls Protobion came after untold millions of years us with our skins, our nails, and our hair; came, too, the serpents with their scales, the birds with their feathers; the horny hide of the rhinoceros and the fairy wings of the butterfly; the shell of the crab, the gossamer loveliness of the moth and the shimmering wonder of the mother-of-pearl. * J. W. Gregory, F.R.S.D.Sc., Professor of Geology, University of Glasgow. “Is there any greater gap between any of these and the metallic? I think not.” “Not materially,” I answered. “No. But there remains--consciousness!” “That,” he said, “I cannot understand. Ventnor spoke of--how did he put it?--a group consciousness, operating in our sphere and in spheres above and below ours, with senses known and unknown. I got--glimpses--Goodwin, but I cannot understand.” “We have agreed for reasons that seem sufficient to us to call these Things metallic, Dick,” I replied. “But that does not necessarily mean that they are composed of any metal that we know. Nevertheless, being metal, they must be of crystalline structure. “As Gregory has pointed out, crystals and what we call living matter had an equal start in the first essentials of life. We cannot conceive life without giving it the attribute of some sort of consciousness. Hunger cannot be anything but conscious, and there is no other stimulus to eat but hunger. “The crystals eat. The extraction of power from food is conscious because it is purposeful, and there can be no purpose without consciousness; similarly the power to work from such derived energy is also purposeful and therefore conscious. The crystals do both. And the crystals can transmit all these abilities to their children, just as we do. For although there would seem to be no reason why they should not continue to grow to gigantic size under favorable conditions--yet they do not. They reach a size beyond which they do not develop. “Instead, they bud--give birth, in fact--to smaller ones, which increase until they reach the size of the preceding generation. And like the children of man and animals, these younger generations grow on precisely as their progenitors!
