Page 325 - It is in vain that we look for genius to reiterate its miracles in the old arts; it is its instinct to find beauty and holiness in new and necessary facts, in the field and road-side, in the shop and mill.
Page 244 - ... set of laws which governs the motions of matter on the earth and in the most distant regions of the heavens ; to find the revolution of the apsides in a pendulum vibrating in ellipses, or the conservation of areas in a ball whirled round by a string suddenly shortened ; or (as in the present case) to perceive a celestial phenomenon, vast in its relations both to time and space, and complex in its conditions, identified, as to its mechanical cause, with the rotatory movement of a little apparatus...
Page 441 - The movement of the upper one was shown by an index, that pointed to the right or to the left according to the direction of the motion.
Page 139 - Charles-terrace, for improvements applicable to guns, cannon, or ordnance, rifles, and other similar implements of war or the chase, for more accurately aiming at the object to be struck by projectiles.
Page 174 - ... of the same nature." This the lecturer found to be generally the case when the hot rocker rested upon a block, or on the edge of a thick plate of the same metal ; but the case was quite altered when a thin plate of metal was used. Thus, a copper rocker laid upon the edge of a penny-piece did not vibrate permanently ; but when the coin was beaten out by a hammer, so as to present a thin, sharp edge, constant vibrations were obtained. A silver rocker resting on the edge of a half-crown refused...
Page 173 - In the year 1805, M. Schwartz, an inspector of one of the smelting works of Saxony, placed a cup-shaped mass of hot silver upon a cold anvil, and was surprised to find that musical tones proceeded from the mass. In the autumn of the same year, Professor Gilbert, of Berlin, visited the smelting works and repeated the experiment. He observed that the sounds were accompanied by a quivering of the hot silver, and that, when the vibrations ceased, the sound ceased also. Professor Gilbert merely stated...
Page 253 - The engine tools employed in the different works are generally similar to those which were used in England some years ago, being much lighter, and less accurate in their construction, than those now in use, and turning out less work in consequence.
Page 173 - Friday evening lecture by Professor Faraday, at the Royal Institution. Professor Faraday expanded and further established the explanation of the sounds given by Mr. Trevelyan and Sir John Leslie. He referred them to the tapping of the hot mass against the cold one underneath it, the taps being in many cases sufficiently quick to produce a high musical note. The alternate expansion and contraction of the cold mass at the points where the hot rocker descends upon it, he regarded as the sustaining power...

Page 386 - But it seemeth clear that if the person incited to take such an oath do not actually take it, the person by whom he was so incited is not guilty of subornation of perjury, yet it is certain that he is liable to be punished, not only by fine, but also by infamous corporal punishment.
