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.

During the partial eclipse of March 8, 1849, the moon's disc assumed an olive-green colour, as represented in fig. 4, Plate 6. The varying appearances which the moon's surface exhibits on such occasions depend evidently on the physical changes perpetually occurring in the earth's surface. CHAPTER XIV. The Planets. General Survey of the Planetary System.--The planetary system, as at present known to astronomers, consists of eight principal planets, viz. Mercury, Venus, the Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, besides the group of minor planets revolving between Mars and Jupiter, which now amount to 106, and the number of which is increasing every year. Moreover, several of the planets are accompanied by satellites. Thus, the Earth is accompanied by one satellite, Jupiter by four, Saturn by eight, Uranus by four, and Neptune by one. The aggregate number of satellites at present known to exist amounts, therefore, to eighteen. The planets may be divided into three classes. First, there are the four interior planets, Mercury, Venus, the Earth, and Mars. These bodies are all of moderate dimensions, are nearly equal in density, and, except in the case of the Earth, are unaccompanied by satellites. Then there is the group of minor planets, which are distinguished by their excessive smallness, and by all revolving within a comparatively narrow zone of the planetary regions. Finally, there are the four exterior planets, which are distinguished by their immense magnitude, by their moderate density, and by the circumstance of their being in every instance accompanied by one or more satellites.
