"'It is true,' returned Chapman, 'but that doesn't explain everything. We sleep less here, we scarcely touch meat, and yet exertion, prolonged by hours, scarcely accelerates the blood or vexes the nerves, and generally we don't grow old. Our bodies are light; the texture, apparently firm and resisting, is somehow diaphanous. I've seen the light through the palm of my hand. And then again I haven't. Somehow mind works in the body here and changes it, and changes it different at different times. Why, Dodd, the other day at the Patenta, a student jumped up with a cry of delight at something, and stumbled and fell from a window to the ground, but he stood up without a bruise or hurt of any kind. His exultation, his emotional excitement made him buoyant, I think, and he fell to the earth like a thistledown. There was no concussion.' "'Well,' I responded, 'I cannot tell. I know very little as yet. I feel wonderfully active and vitalized. My senses are acute. I see further, hear further, smell further than I ever did on earth, and it even seems to me I can anticipate things. The nerve currents are so rapid, the mind seems so persuasive, that coming events are registered by a prophetic feeling I can scarcely describe. For that reason, Chapman, I grow happier every minute, for now I see approaching that great joy, my reunion with Martha, the one great divine event I hunger and hope for. "'Well,' said Chapman, as a cloud covered the scudding moons, 'I do hope you may see her, and somehow I think, too, you will. But, Dodd,' the moons emerged, and the lower one was in transit across the face of the upper, 'I must call your attention to this strange peculiarity of our bodies, that we undergo extremes of temperature with almost no noticeable sense of the great heat or cold. This region we are traversing is about the latitude of Christ Church, as I told you, and it is the period of harvests, and the heat is moderate, but in the height of summer the heat seems scarcely more felt than now, and in the clothing I am now wearing, I have sailed through the ice packs of the North, and slept thinly covered in its snows, but without undue discomfort. I tell you, matter in us, and flesh and blood in us are all differently conditioned.' "'Why not ask these questions of the wise men of the Patenta, the doctors and chemists?' I replied. 'I can think of an analogy that might make this Martian constitution intelligible. A close, dense body conducts heat or cold; a loose, open texture or cellular mass does not. In our curious embodiment from spirit the substance of our bodies is an etherealized matter, loosely, I might say, flocculently, disposed, and while it conveys sensations of a certain tone or key of vibratory intensity, it will not respond to any violent or coarse shocks. They simply cannot be carried. They escape us. Are the people all alike amongst the Martians?'
