Էջ 117 - ... was waiting for the erection of a spire in Philadelphia to carry his views into execution ; not imagining that a pointed rod, of a moderate height, could answer the purpose ; when it occurred to him that, by means of a common kite, he could have a readier and better access to the regions of thunder, than by any spire whatever. Preparing, therefore...
Էջ 187 - ... ones, is plunged a small plate of zinc, and another of silver; these communicate with each other by a thin wire, so fastened that the silver of the first glass is connected with the zinc of the second, the silver of the second with the zinc of the third, and so on. If one hand be now dipped into the first glass, and the other into the last...
Էջ 126 - The thunder holds his black tremendous throne: From cloud to cloud the rending lightnings rage; Till in the furious elemental war Dissolv'd, the whole precipitated mass Unbroken floods and solid torrents pours.
Էջ 68 - Leyden, of much eminence, said that " he felt himself struck in his arms, shoulders, and breast, so that he lost his breath ; and it was two days before he recovered from the effects of the blow and the terror ; adding, that he would not take a second shock for the kingdom of France.
Էջ 138 - The analogy between water-spouts and electricity may be made visible by hanging a drop of water to a wire, communicating with the prime conductor, and placing a vessel of water under it. In these circumstances, the drop assumes all the various appearances of a water-spout, in its rise, form, and mode of disappearing. It is inferred, therefore, that the immediate cause of this extraordinary phenomenon is the attraction of the lower part of the cloud for the surface of the water.
Էջ 223 - ... and parallel to it, no declination is produced either to the east or west; but an inclination takes place, so that the pole, next which the negative electricity enters the wire, is depressed when the wire is situated on the west side, and elevated when situated on the east side.
Էջ 197 - ... the silver. The most powerful galvanic combinations of the second order are, where two conductors of the second class have different chemical actions on the conductors of the first class, at the same time that they act upon each other. Thus copper, silver, or lead, with a solution of an alkaline sulphuret and diluted nitrous acid, form a very active galvanic circle. The following tables of galvanic arrangements were composed by Sir H.
Էջ 212 - It is now known that similar effects may be produced in the limb thus prepared, by only making a communication between the nerves and the muscles, by a conducting substance. Thus, in an animal recently dead, if a nerve be detached from the surrounding parts, and the coverings be removed from over the muscles, which depend on that nerve ; and if a piece of metal, as a wire, touch the nerve with one extremity, and the muscle with the other, the limb will be convulsed. Charles. Is it necessary that...
Էջ 196 - The most active circles of the first order, are two solids of different degrees of oxidability and a fluid capable of oxidating at least one of the solids. Thus gold, silver, and water do not form an active galvanic circle ; but the circle will become active, if a little nitric acid, or any fluid decomposable by silver is mixed with the water. A combination of zinc, silver and water forms an active galvanic circle, and the water is found to oxidate the zinc, provided the water holds some atmospherical...
Էջ 134 - E'en in the depth of polar night, they find A wondrous day : enough to light the chase, Or guide their daring steps to Finland fairs.
