Analysis of the Nebular Hypothesis. Separation from the nebula of the rings for the separate planets, etc. 83 Excessive heat attributed to the nebula erroneous and impossible 84 Centigrade thermometer to be used for temperatures 85 Temperature of the nebula not far from absolute zero 86 Erroneous ideas about glowing gases produced by collisions of their atoms, or particles of cosmic matter in the form of vapours 86 Separation of ring for Neptune. It could not have been thrown off in one mass, but in a sheet of cosmic matter 87 Thickness and dimensions of the ring 88 Uranian ring abandoned, and its dimensions 89 Saturnian ring do. do. 90 Jovian ring do. do. 91 Asteroidal ring do. do. 93 Martian ring do. do. 94 Earth ring do. do. 95 Venus ring do. do. 96 Mercurian ring do. do. 97 Residual mass. Condensation of Solar Nebula to various diameters, and relative temperatures and densities 98 Unaccountable confusion in the mode of counting absolute temperature examined and explained. Negative 274 degrees of heat only equal 2 degrees of absolute temperature 100 The Centigrade thermometric scale no better than any other, and cannot be made decimal 103 The sun's account current with the Nebula drawn up and represented by Table III. 104 CHAPTER VI.
