Stran 79 - ... melt in air, — the flux of power is eternally the same. It rolls in music through the ages, and all terrestrial energy, — the manifestations of life, as well as the display of phenomena, are but the modulations of its rhythm.
Stran 172 - It is conceivable that the various kinds of matter, now recognized as different elementary substances, may possess one and the same ultimate or atomic molecule existing in different conditions of movement. The essential unity of matter is an hypothesis in harmony with the equal action of gravity upon all bodies. We know the anxiety with which this point was investigated by Newton, and the care he took to ascertain that every kind of substance, ' metals, stones, woods, grain, salts, animal substances,'...
Stran 323 - Star be observed to the East and the other to the West of the Meridian, the Time will be determined with rather more certainty.
Stran 81 - In 1845 he published his Memoir on " Organic Motion," and applied the mechanical theory of heat in the most fearless and precise manner to vital processes. He also embraced the other natural agents in his chain of conservation. In 1853 Mr. Waterston proposed, independently, the meteoric theory of the sun's heat, and in 1854 Professor William Thomson applied his admirable mathematical powers to the development of the theory; but six years previously...
Stran 229 - Assuming 4,000 feet as the greatest depth at which it will ever be possible to carry on mining operations, and rejecting all seams of less than two feet in thickness, the entire quantity of available coal existing in these islands has been calculated to amount to about...
Stran 140 - The rain quits the ocean as vapour; it returns to it as water. How are the vast stores of heat, set free by the change from the vaporous to the liquid condition, disposed of ? Doubtless in great part they are wasted by radiation into space. Similar remarks apply to the cumuli of our latitudes. The warmed air, charged with...
