Page 5 - Thy Father has written for thee." " Come, wander with me," she said, "Into regions yet untrod; And read what is still unread In the manuscripts of God." And he wandered away and away With Nature, the dear old nurse, Who sang to him night and day The rhymes of the universe. And whenever the way seemed long, Or his heart began to fail, She would sing a more wonderful song, Or tell a more marvellous tale.
Page 170 - By a delicate mathematical analysis, Thomson arrives at the theorem that the ''average pressure at any point of an incompressible, frictionless fluid, originally at rest, but set in motion and kept in motion by solids, moving to and fro, or whirling round in any manner, through a finite space of it," would explain the attractions just described.

Page 253 - ... effect is proportional to the magnetic intensity of the bar multiplied by the current traversing the coil seems to indicate that in this case the effect is produced by the attraction of the magnetic particles by the coil. But then it will be asked why so remarkable an augmentation of the effect is produced by the increase of tension in the case of the soft iron bars. When we are able to answer this question in a satisfactory manner, we shall probably have a much more complete acquaintance with...
Page 73 - Since it appeared that the purest and densest vapour alone gave the greatest number of lines, it became of interest to examine the spectra of compounds consisting of a metal combined with a nonmetallic element. Experiments with chlorides are recorded. It was found in all cases that the difference between the spectrum of the chloride and the spectrum of the metal was that under the same spark-conditions all the short lines were obliterated. Changing the spark-conditions, the final result was that...
