Page 128 - I could hear from most of the negroes of three plantations, amounting in all to about six or eight hundred. While earnestly listening for the cause, I heard a faint voice near the door calling my name. I arose, and taking my sword, stood at the door. At this moment, I heard the same voice still beseeching...
Page 126 - Thousands of bodies and falling stars succeeded each other during four hours. Their direction was very regular from north to south. From the beginning of the phenomenon there was not a space in the firmament equal in extent to three diameters of the moon which was not filled every instant with bodies or falling stars. All the meteors left luminous traces or phosphorescent bands behind them, which lasted seven or eight seconds.
Page 129 - The scene was truly awful ; for never did rain fall much thicker than the meteors fell towards the earth ; east, west, north, and south it was the same.
Page 71 - ... first the form of a private astronomical expedition, for which his friends in Boston had promised the pecuniary means ; but, under the enthusiastic support of Mr. Sarmiento, at first as Argentine minister to this country, and later as president of that republic, it rapidly broadened, and finally led to the establishment by Dr. Gould of a permanent National Observatory at Cordoba. This marks an epoch in modern astronomy, the equalization of our knowledge of the two celestial hemispheres.
Page 167 - I have found that during a period of 33-25 years, the longitude of the node is increased 20' by the action of Jupiter, nearly 7' by the action of Saturn, and about i' by that of Uranus. The other planets produce scarcely any sensible effects, so that the entire calculated increase of the longitude of the node in the above-mentioned period is about 28'.
Page 71 - It is impossible, in brief space, to describe or characterise the marvellous work here undertaken and so faultlessly pushed to completion by Dr. Gould, during the fifteen years of self-imposed exile from his native land, with unfaltering devotion and energy, in the face of difficulty and domestic bereavement.
Page 163 - The first appearance was that of fireworks of the most imposing grandeur, covering the entire vault of heaven with myriads of fireballs, resembling skyrockets.
Page 218 - PRILLIEUX has been elected a member of the Paris Academy of Sciences, in succession to the late M.
Page 198 - That the separation of Biela's comet as it approached the Sun in December 1845 was but one in a series of similar processes, which would probably continue until the individual fragments would become invisible. 3. That certain luminous meteors have entered the solar system from the interstellar spaces.
Page 290 - That the attractive force of the sun on the matter of this ring is alternately increased and diminished by the operation of the forces which produce the solar spots, being greatest at the times of minimum solar-spot frequency, and least when the spots are most numerous.
