Page 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,'...
Page 79 - 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 an infinitesimal part of the whole.
Page 79 - ... millions, we do not reach the sun's expenditure. And still, notwithstanding this enormous drain, in the lapse of human history, we are 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.

Page 324 - A sudden outburst of light, far exceeding the brightness of the sun's surface, was seen to take place, and sweep like a drifting cloud over a portion of the solar face. This was attended with magnetic disturbances of unusual intensity, and with exhibitions of aurora of extraordinary brilliancy. The identical instant at which the effusion of light was observed was recorded by an abrupt and strongly marked deflection in the self-registering instruments at Kew.
Page 141 - ... capacity, heat: the amount of heat necessary to raise the temperature of a given mass one degree. Numerically, the mass multiplied by the specific heat. capacity reducer: in a compressor, a device such as a clearance pocket, movable cylinder head, or suction bypass, by which compressor capacity can be adjusted without otherwise changing the operating conditions. capillarity...
