Page 25 - The mean solar day is divided into 24 hours, each hour into 60 minutes, and each minute into 60 seconds.
Page 107 - When the contact was made, there was a sudden and very slight effect at the galvanometer, and there was also a similar slight effect when the contact with the battery was broken. But whilst the voltaic current was continuing to pass through the one helix, no galvanometrical appearances nor any effect like induction upon the other helix could be perceived...

Page 115 - Some velocity must be proportional to the reciprocal of the square root of the product of the dielectric constant and the magnetic permeability of an insulating medium.
Page 107 - Two hundred and three feet of copper wire in one length were coiled round a large block of wood; other two hundred and three feet of similar wire were interposed as a spiral between the turns of the first coil and metallic contact everywhere prevented by twine. One of these helices was connected with a galvanometer and the other with a battery of one hundred pairs of plates four inches square, with double coppers, and well charged. When the contact was made there was a sudden and very slight effect...
Page 125 - If we have fewer equations, it possesses "freedom," and the number of "degrees of freedom" is measured by the excess of the number of variables over the number of equations.
