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 82 - 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.

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. A long solid cylinder of...
Page 576 - the conclusion arrived at in the latter part of the last section, that blood flowing through an inflamed part behaves itself in the same way as when separated from the living body, naturally leads us to infer that the tissues of the inflamed part are in some degree approximated to the condition of dead matter, or, in other words, have suffered a diminution of power to discharge the offices peculiar to them as components of the healthy animal frame. This inference is strongly supported by considering...

Page 446 - I would further wish to make it distinctly understood, that no part of the ice, even if supposed at the outset to be solid, or free from porosity, can resist being permeated by the water squeezed against it from such parts as may be directly subjected to the pressure ; because, the very fact of that water being forced against any portions of the ice supposed to be solid, will instantly subject them to pressure, and so will cause melting to set in throughout their substance, thereby reducing them...
