Portrait of Alfred Russel Wallace Alfred Russel Wallace,  Is Mars Habitable? (1907)

“ This effect is further intensified by the fact that a less dense cannot absorb and transmit so much heat as a more dense atmosphere. Here then we have an absolute law of nature to be observed operating everywhere on the earth, and the mode of action of which is fairly well understood. This law is, that reduced atmospheric pressure increases radiation, or loss of heat, more rapidly than it increases insolation or gain of heat, so that the result is always a considerable lowering of temperature. ”

Portrait of Algernon Blackwood Algernon Blackwood,  John Silence, Physician Extraordinary… (1908)

“ Silence pointed to them, but without comment and without pausing, and the sight of them woke in me a singular realisation of the dread that lay so far only just out of sight in this adventure.
It was exhausting work, and heavy going. We kept close together. The warmth, too, was extraordinary. Yet it did not seem the warmth of the body due to violent exertion, but rather an inner heat of the mind that laid glowing hands of fire upon the heart and set the brain in a kind of steady blaze.

Portrait of Algernon Blackwood Algernon Blackwood,  Three John Silence Stories

“ Silence said.
“Yes, you saw that, of course; my atmosphere must convey that much to any one with psychic perceptions. Besides which, I feel sure from all I’ve heard, that you are really a soul-doctor, are you not, more than a healer merely of the body?”
“You think of me too highly,” returned the other; “though I prefer cases, as you know, in which the spirit is disturbed first, the body afterwards.”
“I understand, yes. Well, I have experienced a curious disturbance in—not in my physical region primarily. I mean my nerves are all right, and my body is all right.
