Página 373 - 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.
Página 69 - It is hardly necessary to add that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner the Heat was excited and communicated in these experiments, except it be MOTION.
Página 446 - 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.
Página 65 - Heat is a motion, expansive, restrained, and acting in its strife upon the smaller particles of bodies. But the expansion is thus modified ; while it expands all ways, it has at the same time an inclination upwards. And the struggle in the particles is modified also ; it is not sluggish, but hurried and with violence.

Página 108 - The immediate cause of the phenomena of heat then is motion, and the laws of its communication are precisely the same, as the laws of the communication of motion.
Página 109 - ... 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 the...
Página 66 - No such change, however, had taken place, for the chips were found to have the same capacity as slices of the same metal cut by a fine saw, where heating was avoided. Hence, it is evident, that the heat produced could not possibly have been furnished at the expense of the latent heat of the metallic chips.
Página 67 - The cylinder, revolving at the rate of about 32 times in a minute, had been in motion but a short time, when I perceived, by putting my hand into the water and touching the outside of the cylinder, that Heat was generated ; and it was not long before the water which surrounded the cylinder began to be sensibly warm.
Página 109 - ... 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.
