Excerpt from A Journey to the Earth's Interior, or Have the Poles Really Been Discovered The Copernican system of astronomy was a step in advance of the Ptolemaic system just be cause it enabled scientists to discover many new facts about the solar system which the error of the old view had hidden from their gaze. My own theory adds to the valuable results gained by the Copernican System, not by subverting it - for I imagine that no sane person would now try to do that - but by accepting it fully, and adding to it a different theory of the evolution of the several planets from their nebulae, and from this new theory of evolution deducing cer tain presumptions about the interior of the earth. These presumptions I have supported by a wealth of facts discovered by the telescopic observations of astronomers of nebulae and one of our sister planets, Mars, and made by ex plorers of the most fascinating parts of our own planet - the polar regions.
