Page 55 - It thus appears that a long extended group of meteor-particles must accompany the comet in its periodical revolution, preceding it to a distance of 300 millions of miles in front, and following it to a length of 200 millions of miles in the rear of its actual position, or occupying, if there is no reason to suppose this elongated meteor-current discontinuous, fully 500 millions of mües in its observed length along the comet's path.

Page 425 - These strata of increased density will in projection be made manifest in the form of luminous and nearly concentric arcs whose greatest brilliancy will, in general, be near the most advanced part of each stratum, and gradually diminish in brightness as they curve away to form the comet's tail. 6. The coronal matter, owing to its retardation, grows so dense that it also becomes visible, and with the comet's atmosphere, is finally driven into the tail by the repeated bombardment of unretarded following...
