Стр. 226 - Accurate and minute measurement seems to the non-scientific imagination a less lofty and dignified work than looking for something new. But nearly all the grandest discoveries of science have been but the rewards of accurate measurement and patient long-continued labour in the minute sifting of numerical results.
Стр. 182 - Thus showing it is the earth not the stars which move : — " On another occasion Aryabhata says, ' the sphere of the stars is stationary; and the earth, making a revolution, produces the daily rising and setting of stars and planets.
Стр. 259 - Hence and because we all confidently believe that there are at present, and have been from time immemorial, many worlds of life besides our own, we must regard it as probable in the highest degree that there are countless seed-bearing meteoric stones moving about through space. If at the present instant no life existed upon this earth, one such stone falling upon it might, by what we blindly call natural causes, lead to its becoming covered with vegetation.
Стр. 203 - Look up, and behold the eternal fields of light that lie round about the throne of God. Had no star ever appeared in the heavens, to man there would have been no heavens ; and he would have laid himself down to his last sleep, in a spirit of anguish, as upon a gloomy earth vaulted over by a material arch, solid and impervious.
Стр. 271 - Aztecs had ascertained with considerable precision the respective days of the two passages of the sun by the zenith of Mexico, of the two equinoxes, and of the summer and winter solstices. They had therefore six different means of ascertaining and verifying the length of the solar year by counting the number of days elapsed till the sun returned to each of these six points, — the two solstices, the two equinoxes, and the two passages by the zenith.
Стр. 178 - After this, in the Lent, the sun and the day darkened about the noon-tide of the day, when men were eating; and they lighted candles to eat by. That was the thirteenth day before the kalends of April. Men were very much struck with wonder.
Стр. 54 - Moon's disk. This observation would seem to show, as has been already suggested, that some of the light from the true surroundings of the Sun is scattered by some medium between the eye and the Moon, and therefore the distance from the Moon to which these lines can be traced does not imply necessarily an equally great extension of the true halo. Lieut. Brown, of Lord Lindsay's party, saw only a continuous spectrum without bright lines, from 4^' to 25
Стр. 205 - ... to the eye, must have been more than nineteen hundred and ten thousand, that is, almost two millions of years on their way ; and that, consequently, so many years ago,' this object must already have had an existence in the sidereal heavens, in order to send out those rays by which . we now perceive it.
Стр. 183 - PRIT'HUDACA, either correcting his quotations, or vindicating the doctrine of the earlier author), it appears, that ARYABHAT'T'A affirmed the diurnal revolution of the earth on its axis; and that he accounted for it by a wind or current of aerial fluid, the extent of which, according to the orbit assigned to it by him, corresponds to an elevation of little more than a hundred miles from the surface of the earth ; that he possessed the true theory of the causes of lunar and solar eclipses, and disregarded...
Стр. 52 - August, 1 869, attention was called to the two apparently distinct portions besides the prominences in the light seen round the Moon during totality. The American pictures showed similar indications of brighter portions near the Sun's limb, within which the eruptions of hydrogen forming the prominences take place, to those which were visible in the photographs taken by Mr. De La Rue in 1860, and by Major Tennant and Dr.
