Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1895 edition. Excerpt: ...condensations as may possibly produce comets of the symmetrical form we observe in them upon planetary conditions, and, therefore, such as are outwardly, as it appears to me, evidently moving under the direction of symmetrical orbital law. In the extensive volume of pneuma considered as the extreme field of comet-formation, which would be subject to the influence of the near stars almost as much as that of our sun, 76, the centralizing influence of gravitation would have little effect in changing the natural formation of individual systems of matter after they were once constituted. Therefore, assuming original motion in the pneuma such as we have found necessary for the formation of our solarplanetary system, 62, such motion must, as before stated, have extended to all parts of the solar pneuma. If any original isolated system, of large volume in its original state, were in slow revolution with its parts moving at equal angular velocity, then upon its condensation to a smaller volume its rotative velocity would increase, as previously discussed for solar rotation, 116. This rotation of any part of the system would be maintained in projection sunward, and if in free matter projected from a great distance, it would form a comet of long period. 170. Comets of short period.--These possibly depended in many instances for their orbit upon deflection of the matter of the comets of long period by the influence of planetary attractions. At any early epoch such long-period comets, moving at high velocities by accumulated gravitation in falling from a distant part of space, would fall into the solarplanetary nebula or into any detached zone-ring of nebular matter which may have been present at the time moving at orbital velocity round...show more
