To see how far the influence of the oxidized end of the wire goes , I took an iron
wire of 50 ' in length and 0 . 5 in thickness , heated one of its ends about 3 " in
length , immersed it in the acid of the strength above mentioned , and afterwards
put ...

It does not permit nie to suppose that a part of the discharge , when the wire is
very fine , is transmitted by the air and the neighbouring bodies , or at least that
such a part could have any sensible influence . In fine , in order to discard the ...

The envelopes tried were perhaps too thin , their influence being insensible . The
small difference of action of the two envelopes of unequal thickness is without
doubt , the part of the effect due to the continuous current . I am far from well ...

The evils attending these conductors , arise , principally , from lateral explosions
and electro - magnetic influence . I have already illustrated the magnetic effects of
electric discharges on a miniature scale , and from these we can form a good ...

Seite 427 - ... a wire down the outside of the building into the ground, or down round one of the shrouds of a ship, and down her side till it reaches the water?
Seite 414 - To determine the question whether the clouds that contain lightning are electrified or not, I would propose an experiment to be tried where it may be done conveniently.
Seite 151 - By exposure to excessive cold the primitive fungi are killed, but their seed still retains vitality, and, if immersed in snow, which appears to be their native soil, they reproduce new fungi, which are generally of a red colour. The Philosophical Transactions for 1823 contains the paper by Mr. Bauer already alluded to, entitled " Microscopical Observations on the Suspension of the Muscular Motions of the Vibrio tritici," which forms the Croonian Lecture for that year.
Seite 336 - The declaration was in the usual form, and the defendants pleaded thereto, first, that they were not guilty; secondly, that the plaintiff was not the...
Seite 414 - ... or 30 feet, pointed very sharp at the end. If the electrical stand be kept clean and dry, a man standing on it when such clouds are passing low, might be electrified and afford sparks, the rod drawing fire to him from a cloud.
Seite 377 - Fig. 9,) big enough to contain a man and an electrical stand. From the middle of the stand let an iron rod rise and pass bending out of the door, and then upright twenty or thirty feet, pointed very sharp at the end. If the electrical stand be kept clean and dry, a man standing on it, when such...
Seite 484 - ... will give a spark at a greater distance. Two gun-barrels united, and as highly electrified, will give a spark at a still greater distance. But if two gun-barrels electrified will strike at two inches distance, and make a loud snap, to what a great distance may 10,000 acres of electrified cloud strike and give its fire, and how loud must be that crack?
Seite 414 - If any danger to the man should be apprehended (though I think there would be none) let him stand on the floor of his box, and now and then bring near to the rod the loop of a wire that has one end fastened to the leads, he holding it by a wax handle ; so the sparks, if the rod is electrified, will strike from the rod to the wire, and not affect him.
Seite 377 - I say, if these things are so, may not the knowledge of this power of points be of use to mankind, in preserving houses, churches, ships, &V. from the stroke of lightning, by directing us to fix on the highest parts of those edifices, upright rods of iron made sharp as a needle, and gilt to prevent rusting, and from the foot of those rods a wire down the outside of the building into the ground, or down round one of the shrouds of a ship...
Seite 73 - The mutual action between the elements of the food and the oxygen conveyed by the circulation of the blood to every part of the body is the source of animal heat. " All living creatures whose existence depends on the absorption of oxygen possess within themselves a source of heat independent of surrounding objects.
