Page 207 - These processes owe their power almost wholly to the action of other heavenly bodies, particularly to the light and heat of the sun, and partly also, in the case of the tides, to the attraction of the sun and moon.
Page 244 - speck of ice," to use his own words, could be seen.

Page 194 - ... higher. In this way its mass would ascend : and at the moment when its highest point has been attained, it would represent the same number of raised foot-pounds as before it fell, never a greater number ; that is to say, living force can generate the same amount of work as that expended in its production. It is therefore equivalent to this quantity of work. Our clocks are driven by means of sinking weights, and our watches by means of the tension of springs. A weight which lies on the ground,...

Page 194 - ... by means of sinking weights, and our watches by means of the tension of springs. A weight which lies on the ground, an elastic spring which is without tension, can produce no effects : to obtain such we must first raise the weight or impart tension to the spring, which is accomplished when we wind up our clocks and watches. The man who winds the clock or watch communicates to the weight or to the spring a certain amount of power, and exactly so much as is thus communicated is gradually given...
