Thus, if a pillar of metal one hundred inches in height, being raised in temperature, is augmented in height by a quarter of an inch, the force with which such increase of height is produced is equal to a weight which being placed upon the top of the pillar would compress it so as to diminish its height by a quarter of an inch. In the same manner, if a rod of metal one hundred inches in length be contracted by diminished temperature so as to render its length a quarter of an inch...
Page 462 - THE immense progress made in investigating Roman history and antiquities within the last thirty or forty years, having materially altered the whole complexion of that study, has rendered indispensable a new manual, for the use of schools, removing the old errors and misconceptions which have long since been exposed and exploded by scholars.

Page 311 - The astronomical universe consists of masses, undoubtedly of great magnitude, but separated by such immense distances that they appear to us as material points ; these points attract each other in the inverse ratio of the squares of their distances, and this attraction is the only force which affects their motion. But if our senses were keen enough to show us all the details of the bodies which the physicist studies, the spectacle thus disclosed would hardly differ from the one which the astronomer...

Page 222 - The thread is fixed at the top to a small windlass t, by which the needle can be raised or lowered, and the whole is included in a glass cage, to preserve the apparatus from the disturbance of the air. Upon this glass cage, which is cylindrical, is a graduated circle dd!, which measures the angle through which the needle is deflected.
