“If animals emit wave lengths in the ether which include most of the heat and visible portions of the solar spectrum, there would seem to be no reason why ultra-violet undulations should not be similarly produced. When these latter are emitted from the human body, some of them may be the true source of the aura surrounding men and women. This statement does not imply any specific part of the ultra-violet spectrum.”

The Human Atmosphere, by Walter J. Kilner, [1920]
