Faraday's second group of researches and discoveries embrace the chemical phenomena of the current. The dominant result here is the great law of definite Electro-chemical Decomposition, around which are massed various researches on Electro-chemical Conduction and on Electrolysis both with the Machine and with the Pile.
It is probable that the noseleaf, which forms an extended screen stretched behind the nostrils in some of the bats, may be intended by nature to facilitate the collection and conduction of odours, just as the vast expansion of the shell of the ear in the same family is designed to assist in the collection of sounds and thus to supplement their vision when in pursuit of prey in the dusk by the superior sensitiveness of the organs of hearing and smell.
In this instance one of the motor terminals is connected to the insulated plate or body located within the alternating electrostatic field, and the other terminal preferably to the ground. It is quite possible, however, that such "no-wire" motors, as they might be called, could be operated by conduction through the rarefied air at considerable distances.
If an hypothesis were invented to cover this case there would still remain a puzzle in the fact that alloys of metals do not act at all like the pure metals themselves, the electrical resistance of such alloys being, for the most part, unaffected by changed temperature. On the whole, then, the facts of electrical conduction at low temperatures are quite beyond the reach of present explanation.
On May 23, 1833, he read a paper before the Royal Society 'On a new Law of Electric Conduction. He found that, though the current passed through water, it did not pass through ice: why not, since they are one and the same substance?
In recording my investigations on the subject of radiant matter and the state of gaseous residues in high vacua under electrical strain, I must refer to certain attacks on the views I have propounded. This volume contains two memoirs, one by Hittorff on the "Conduction of Electricity in Gases," and the other by Puluj on "Radiant Electrode Matter and the So-called Fourth State." Dr.
In a word, therefore, all metal bodies in a building should, as far as possible, be made a part of the system of conduction. This matter is not well understood generally. A dwelling in Boston having been struck by lightning a few years since, a neighbor remarked that "it was fortunate the lightning did not reach the gas-pipe, for it would then have gone all over the house."
But the action as explained implies that the air is insulating that is, that it is composed of independent carriers immersed in an insulating medium. This is the case only when the air is at something like ordinary or greater, or at extremely small, pressure. When the air is slightly rarefied and conducting, then true conduction losses occur also.
With the assistance of Professor Rubens and of Herr W. Rathenau, this physicist effected, at the request of the German Ministry of Marine, a series of researches which enabled him, by means of a compound system of conduction and induction by alternating currents, to obtain clear and regular communications at a distance of four kilometres.
On Friday, January 19, 1844, he opened the weekly evening-meetings of the Royal Institution by a discourse entitled 'A speculation touching Electric Conduction and the nature of Matter. In this discourse he not only attempts the overthrow of Dalton's Theory of Atoms, but also the subversion of all ordinary scientific ideas regarding the nature and relations of Matter and Force.
