Page 254 - Geology and Mineralogy, considered with reference to Natural Theology,
Page 140 - The explanation of all phenomena of electromagnetic attraction or repulsion, and of electromagnetic induction, is to be looked for simply in the inertia and pressure of the matter of which the motions constitute heat. Whether this matter is or is not electricity, whether it is a continuous fluid interpermeating the spaces between molecular nuclei, or is itself molecularly grouped ; or whether all matter is continuous, and molecular heterogeneousness consists in finite vortical or other relative motions...
Page 140 - Kelvin (now 40 years ago*) gave the solution of the following problem : — Let the two ends of a cord of any length be attached to two points at the ends of a horizontal arm made to rotate round a vertical axis through its middle point at a constant angular velocity, and let a second cord bearing a material point be attached to the middle of the first cord. .The motion now is investigated in the case when the point is infinitely little disturbed from its position of equilibrium.
Page 470 - But there is another thing common to all rhythmically acting organs; they are all the seats of nutritive processes; and I believe that their movements are rhythmical, because their nutrition is so; and rhythmic nutrition is, I believe, only a peculiar instance, or method of manifestation, of a general law of Time as concerned in all organic processes. In other words, I believe that rhythmic motion is an issue of rhythmic nutrition, ie of a method of nutrition, in which the acting parts are at certain...

Page 289 - Helmholtz's galvanometer, with or without modification. The time of vibration of the suspended magnet, and the efficiency of the copper damper, will be so arranged, that during the electric pulse the suspended magnet will turn from its position of equilibrium into a position of maximum deflection, and will fall back to rest in its position of equilibrium. The possibility of fulfilling these conditions is obvious from the form of the curve I have found to represent the electric pulse. The observer...
Page 121 - ... or closed. The hydrostatic pressure applied to force the liquid through any of the tubes will cause them to swell, and to press against the others, which will thus, by peristaltic action, compel the liquid contained in them to move in different parts of them in one direction or the other.
Page 137 - I am directed by the lords commissioners of her Majesty's treasury to acquaint you that, from information which has been received, it has become necessary to take additional means for preventing any such attempt.
Page 88 - And we are fully persuaded, that with reasonable precautions, it will always be possible to provide for the accurate restoration of standards by means of material copies which have been carefully compared with them, more securely than by reference to any experiments referring to natural constants.
Page 181 - Since we find that the hydrogen-molecules in polybasic acids are replaceable by two or more molecules of different metals or radicals, — witness tartrate of potassium and sodium, oxalovinate of potassium, — the idea naturally suggests itself that the biatomic alcohol-forming radicals may be capable of uniting two molecules of different elements or compounds of the oxygen-group: It is probable, for instance, that the ethionic acid, discovered by M. Magnus, may be such a compound, namely ethylene-sulphuro-sulp...
