E E represents the Earth; W W the “great deep,” or the waters which surround the land; N the northern centre; and S S sections of the southern ice. As the present description is purely zetetic, and as every fact must therefore have its fullest value assigned to it, and its consequences represented, a peculiarity must be pointed out in the foregoing diagram. It will be observed that from about the points E E the surface of the water rises towards the south S S. It is clearly ascertained that the altitude of the water in various parts of the world is much influenced by the pressure of the atmosphere--however this pressure is caused--and it is well known that the atmospheric pressure in the south is constantly less than it is in the north, and therefore the water in the southern region must always be considerably higher than it is in the northern. Hence the peculiarity referred to in the diagram. The following quotation from Sir James Ross’s voyages, p. 483, will corroborate the above statements:--“Our barometrical experiments appear to prove that a gradual diminution of atmospheric pressure occurs as we proceed southwards from the tropic of Capricorn. * * * It has hitherto been considered that the mean pressure of the atmosphere at the level of the sea was nearly the same in all parts of the world, as no material difference occurs between the equator and the highest northern latitudes. * * * The causes of the atmospheric pressure being so _very much less_ in the southern than in the northern hemispheres remains to be determined.” Thus, putting all theories aside, we have seen that direct experiment demonstrates the important truth, _that the Earth is an extended Plane_. Literally, “Stretched out upon the waters;” “Founded on the seas and established on the floods;” “Standing in the water and out of the water.” How far the southern icy region extends horizontally, or how deep the waters upon and in which the earth stands or is supported are questions which cannot yet be answered. In Zetetic philosophy the foundation must be well secured, progress must be made step by step, making good the ground as we proceed; and whenever a difficulty presents itself, or evidence fails to carry us farther, we must promptly and candidly acknowledge it, and prepare for future investigation; but never fill up the inquiry by theory and assumption. In the present instance there is no practical evidence as to the extent of the southern ice and the “great deep.” Who shall say whether the depth and extent of the “mighty waters” _have_ a limit, or constitute the “World without end?”
