Page 401 - I have seen the wild stone-avalanches of the Alps, which smoke and thunder down the declivities with a vehemence almost sufficient to stun the observer. I have also seen snow-flakes descending so softly as not to hurt the fragile spangles of which they were composed ; yet to produce from aqueous vapour a quantity, which a child could carry, of that tender material, demands an exertion of energy competent to gather up the shattered blocks of the largest stone-avalanche I have ever seen, and pitch...
Page 117 - I obtained a tolerably bright solar spectrum, and brought a flame coloured by sodium vapour in front of the slit. I then saw the dark lines D change into bright ones.
Page 389 - The sun's rays are the ultimate source of almost every motion which takes place on the surface of the earth. By its heat are produced all winds, and those disturbances in the electric equilibrium of the atmosphere which give rise to the phenomena of lightning, and probably also to those of terrestrial magnetism and the aurora.
Page 193 - Herschel,' would come, on this view of the subject, to be assimilated to those regions on the Earth's surface in which, for the moment, hurricanes and tornadoes prevail — the upper stratum being temporarily carried downwards, displacing by its impetus the two strata of luminous matter beneath...
Page 409 - ... melt in air, — the flux of power is eternally the same. It rolls in music through the age^s, and all terrestrial energy, — the manifestations of life as well as the display of phenomena, are but the modulations of its rhythm.
Page 407 - Still, presented rightly to the mind, the discoveries and generalisations of modern science constitute a poem more sublime than has ever yet been addressed to the imagination. The natural philosopher of to-day may dwell amid conceptions which beggar those of Milton.
Page 408 - ... unable to detect a diminution of his store ; measured by our largest terrestrial standards, such a reservoir of power is infinite ; but it is our privilege to rise above these standards and to regard the sun himself as a speck in infinite extension — a mere drop in the universal sea. We analyze the space in which he is immersed, and which is the vehicle of his power.
Page 205 - By degrees, accounts began to pour in of great Auroras seen on the nights of those days ; not only in these latitudes, but at Rome ; in the West Indies ; on the tropics within 18° of the equator (where they hardly ever appear), nay, what is still more striking, in South America and in Australia ; where, at Melbourne, on the night of the 2d of September the greatest Aurora ever seen there made its appearance.
Page 183 - Hence he concludes that the sun has a very extensive atmosphere, which consists of elastic fluids that are more or less lucid and transparent ; and of which the lucid ones furnish us with light. This atmosphere, he...
Page 321 - The corona was far broader than that which I saw in 1842; roughly speaking, its breadth was little less than the moon's diameter ; but its outline was very irregular. I did not remark any beams projecting from it which deserved notice as much more conspicuous than the others ; but the whole was beamy, radiated in structure, and terminated (though very indefinitely) in a way which reminded me of the ornament frequently placed round a mariner's compass. Its colour was white...
