THE TEMPERATURE OF MARS--MR. LOWELL'S ESTIMATE. We have now to consider a still more important and fundamental question, and one which Mr. Lowell does not grapple with in this volume, theactual temperatures on Mars due to its distance from the sun and theatmospheric conditions on which he himself lays so much stress. If I amnot greatly mistaken we shall arrive at conclusions on this subjectwhich are absolutely fatal to the conception of any high form of organiclife being possible on this planet.... _The Problem of Terrestrial Temperatures. _ In order that the problem may be understood and its importanceappreciated, it is necessary to explain the now generally acceptedprinciples as to the causes which determine the temperatures on ourearth, and, presumably, on all other planets whose conditions are notwholly unlike ours. The fact of the internal heat of the earth whichbecomes very perceptible even at the moderate depths reached in minesand deep borings, and in the deepest mines becomes a positiveinconvenience, leads many people to suppose that the surface-temperatures of the earth are partly due to this cause.
