Pāgina 359 - DUKE'S PALACE. [Enter DUKE, CURIO, LORDS; MUSICIANS attending.] DUKE. If music be the food of love, play on, Give me excess of it; that, surfeiting, The appetite may sicken and so die.— That strain again;— it had a dying fall; O, it came o'er my ear like the sweet south, That breathes upon a bank of violets, Stealing and giving odour.— Enough; no more; 'Tis not so sweet now as it was before.
Pāgina 91 - It seems possible to account for all the phenomena of heat, if it be supposed that in solids the particles are in a constant state of vibratory motion, the particles of the hottest bodies moving with the greatest velocity and through the greatest space ; that in...
Pāgina 91 - ... the particles move round their own axes, and separate from each other, penetrating in right lines through space. Temperature may be conceived to depend upon the velocities of the vibrations ; increase of capacity, on the motion being performed in greater space ; and the diminution of temperature, during the conversion of solids into fluids or gases, may be explained on the idea of the loss of vibratory motion, in consequence of the revolution of particles round their axes, at the moment when...
Pāgina 389 - The refrigeration at night is extreme when the air is dry. The removal, for a single summer night, of the aqueous vapour from the atmosphere which covers England, would be attended by the destruction of every plant which a freezing temperature could kill. In Sahara, where 'the soil is fire and the wind is flame,' the cold at night is often painful to bear.
Pāgina 488 - Look at the integrated energies of our world — the stored power of our coal-fields ; our winds and rivers ; our fleets, armies and guns. What are they ? They are all generated by a portion of the sun's energy, which does not amount to vsTfTnhfwTfTS of tne whole.
Pāgina 91 - ... and elastic fluids, besides the vibratory motion, which must be conceived greatest in the last, the particles have a motion round their own axes with different velocities, the particles of elastic fluids moving with the greatest quickness ;. and that in ethereal substances the particles move round their own axes, and separate from each other, penetrating in right lines through space.
Pāgina 452 - I had often, in the pride of half knowledge, smiled at the means frequently employed by gardeners, to protect tender plants from cold, as it appeared to me impossible, that a thin mat, or any such flimsy substance, could prevent them from attaining the temperature of the atmosphere, by which alone I thought them liable to be injured. But, when I had learned, that bodies on the surface of the earth become, during a still and serene night, colder than the atmosphere, by radiating their heat to the...
Pāgina 91 - ... lower temperature, that is, can give an expansive motion to its particles, it is a probable inference that its own particles are possessed of motion; but as there is no change in the position of its parts as long as its temperature is uniform, the motion, if it...
Pāgina 47 - From whence comes the Heat actually produced in the mechanical operation above mentioned ? Is it furnished by the metallic chips which are separated by the borer from the solid mass of metal ? If this were the case, then, according to the modern doctrines of latent Heat, and of caloric, the capacity for Heat...
Pāgina 47 - If this were the case, then, according to the modern doctrines of latent Heat, and of caloric, the capacity for Heat of the parts of the metal, so reduced to chips, ought not only to be changed, but the change undergone by them should be sufficiently great to account for all the Heat produced.
