Geographical Distribution of Meteoric Stones--Do Aerolitic Falls occur more frequently by Day than by Night?--Do Meteorites, Bolides, and the matter of ordinary Shooting-stars, coexist in the same Rings? 56
In regard to the physical history of those meteoric masses which, in such infinite numbers, traverse the interplanetary spaces, our knowledge is exceedingly limited. Such as hav...
9. CHAPTER III.It is now well known that much greater variety obtains in the structure of the solar system than was formerly supposed. This is true, not only in regard to the magnitudes and de...
7. CHAPTER I.Although shooting-stars have doubtless been observed in all ages of the world, they have never, until recently, attracted the special attention of scientific men. The first exac...
8. CHAPTER II.Muschenbroek, in his _Introduction to Natural Philosophy_, published in 1762, called attention to the fact that shooting-stars are more abundant in August than in any other part...
12. CHAPTER VI.It is well known that great variety has been found in the composition of aerolites. While some are extremely hard, others are of such a nature as to be easily reducible to powde...
15. CHAPTER IX.Of the various theories proposed by astronomers to account for the origin of the sun's light and heat, only two have at present any considerable number of advocates. These are--
11. CHAPTER V.Professor Charles Upham Shepard, of Amherst College, who has devoted special attention to the study of meteoric stones, has designated two districts of country, one in each cont...
19. CHAPTER XIII.The mean distances of the minor planets between Mars and Jupiter vary from 2·20 to 3·49. The breadth of the zone is therefore 20,000,000 miles greater than the distance of the e...
17. CHAPTER XI.Besides the _cosmical_ theory of aerolites which has been adopted in this work, and which is now accepted by a great majority of scientific men, at least four others have been p...
10. CHAPTER IV.It is highly probable that aerolites and shooting-stars are derived either from rings thrown off in the planes of the solar or planetary equators, or from streams of nebulous ma...
14. CHAPTER VIII.An analysis of any extensive table of meteorites and fire-balls proves that a greater number of aerolitic falls have been observed during the months of June and July, when the e...
6. CHAPTER XIV.THE SOLAR SYSTEM consists of the sun, together with the planets and comets which revolve around him as the center of their motions. The sun is the great controlling orb of this...
13. CHAPTER VII.The able and original researches of the celebrated Reichenbach, who has made meteoric phenomena the subject of long-continued and enthusiastic investigation, have attracted the...
16. CHAPTER X.Having shown that meteor-asteroids are diffused in vast quantities throughout the universe; that according to eminent physicists the solar heat is produced by the precipitation...
18. CHAPTER XII.Until about the middle of the present century the rings of Saturn were universally regarded as solid and continuous. The labors, however, of Professors Bond and Pierce, of Cambr...

3. CHAPTER VIII.Does the Number of Aerolitic Falls vary with the Earth's Distance from the Sun?--Relative Numbers observed in the Forenoon and Afternoon--Extent of the Atmosphere as indicated b...
