This little book is a reproduction, combined and somewhat enlarged, of five previous monographs pertaining to the same subject, which, during the past thirty years, I have published in pamphlet form, one thousand at a time, for free distribution among friends. Those editions having been exhausted, I have, at the request of several friends and correspondents, decided to thus combine and publish again my views on the subjects involved, for the candid consideration of thoughtful readers.I am not unaware that most people do not regard as important the question whether the universe is cooling off, whether the earth is eternal, or whether our natural light and heat proceed as such from a red-hot sun. Those of an inquiring mind would, however, it seems to me, desire to perceive the folly of current theories on those subjects and to know the truth. To this end, I have endeavored here to disclose the fallacies and approach the facts.
