Side 408 - CLIFFORD — THE ELEMENTS OF DYNAMIC. An Introduction to the Study of Motion and Rest in Solid and Fluid Bodies.
Side 381 - ... discharge there may be strata ; for we have found a development of heat in the middle of a tube, in which there was no illumination except on the terminals. 8. Even when the strata are to all appearance perfectly steady, a pulsation can be detected in the current ; but it is not proved that the strata depend upon intermittence. 9. There is no current from a battery through a tube divided by a glass division into two chambers, and the tube can only be illuminated by alternating charges. 10. In...
Side 246 - Ibs. pressure. The trumpet was pointed to windward, and in the axis of the instrument the sound was about as effective as that of the 8-oz. rocket. But in a direction at right angles to the axis, and still more in the rear of this direction, the syren fell very sensibly behind even the 2-oz. rocket. These are the principal comparative trials made between the gun-cotton rocket and other fog-signals ; but they are not the only ones. On the 2nd of August, 1877, for example, experiments...
Side 242 - It is to this rapid power of readjustment, this refusal, so to speak, to allow its atoms to be crowded together or to be drawn apart, that Professor Stokes, with admirable penetration, refers the damping power, first described by Sir John Leslie, of hydrogen upon sound. A tuning-fork which executes 256 complete vibrations in a second, if struck gently on a pad and held in free air, emits a scarcely audible note. It behaves to some extent like the pendulum bob just referred to. This feebleness is...
Side 403 - Recherches sur la structure de l'appareil digestif et sur les phénomènes de la digestion chez les Aranéides dipneumones. '1«, 2° et 3° parties.
Side 269 - Harrison (George L.) Chapters on Social Science as connected with the Administration of State Charities.
Side 103 - ... inoculated pigs will be furnished when full details of the experiments are published. In the meantime, it may, however, be noted that it is not mentioned that bacilli were found in the blood of the inoculated animals. Dr. Klein states that the cultivated liquids proved, on microscopic examination, to be " the seat of the growth and development of a kind of bacterium which has all the characters of Eacilku tubtilit (Cohn) " — a figure of which, copied from i " Bericht iiber die Thierarzneiwissenschaft,"...
Side 243 - Woolwich must have been surprised at the mildness of its thunder. To avoid the strain resulting from quick combustion, the powder employed is composed of lumps far larger than those of the pebble-powder above referred to. In the long tube of the gun these lumps of solid matter gradually resolve themselves...
Side 244 - The lantern of the rock lighthouse might suffer from concussion near at hand. and though mechanical arrangements might be devised, both in the case of the lighthouse and of the ship's deck, to place the firing-point of the gun-cotton at a safe distance, no such arrangement could compete, as regards simplicity and effectiveness, with the expedient of a gun-cotton rocket. Had such a means of signalling existed at the Bishop's Eock lighthouse, the ill-fated
Side 243 - An immediate augmentation of the sound of the fork is the consequence. The more rapid the shock imparted to the air, the greater is the fractional part of the energy of the shock converted into wave motion. And as different kinds of gunpowder vary considerably in their rapidity of combustion, it may be expected that they will also vary as producers of sound. This theoretic inference is completely verified by experiment. In a series of preliminary trials conducted at Woolwich on the 4th of June, 1875,...
