That the proximity of the northward pole of a magnet again produces the former, of the southward pole the latter; of the negative wire of a voltaic pile, the former, of the positive wire, the latter; finally, that the two hands are equally and similarly efficient, the right acting like the negative influence, the left like the positive, of those above specified.
Mazarin bounded in his bed as if he had been put in relation with a Leyden jar or a voltaic pile, at the same time that a surprise, or rather a manifest disappointment, inflamed his features with such a blaze of anger, that Louis XIV., little diplomatist as he was, saw that the minister had hoped to hear something else.
The chance work of seven years has produced without me a discovery I have sought for sixteen years. How? My God, I know not yes, I left sulphide of carbon under the influence of a Voltaic pile, whose action ought to have been watched from day to day. During my absence the power of God has worked in my laboratory, but I was not there to note its progressive effects! Is it not awful?
These were intended to explode under water, and some were fired by voltaic batteries, but invariably failed of going off at the proper time; others exploded on being struck; but though the Merlin ran on to one, which went off under her bottom, comparatively slight damage was done her.
They are all in circuit one with another, and a wire connects the ends of each coil to corresponding metal bars on the commutator C. These bars are insulated from each other on the spindle X of the armature. Now, as each coil passes through the magnetic field in turn, a current is excited in it. Each coil therefore resembles an individual cell of a voltaic battery, connected in series.
"I do not know," she said, "why you should imagine " "Stop!" I exclaimed; "there is no imagination in the case. I have reasoned it out. Here is a book I found in the library on electric organs as they are discovered to exist in certain fish. Listen: 'They are nervous apparatuses which in the arrangement of their parts may be compared to a Voltaic pile.
This difference of sensation between the effects of electric fishes and those of a Voltaic battery or a Leyden jar feebly charged has struck every observer; there is, however, nothing in this contrary to the supposition of the identity of electricity and the galvanic action of fishes.
Again, by turning the machine contrary to the direction of the attractive forces, so as to increase the intensity of the voltaic current by the assistance of the magneto-electricity, he found that the evolution of heat was still proportional to the square of the current.
When I caused one of the poles of my magnet to slowly approach the voltaic arc, I ascertained that, at a distance of 10 centimeters, the arc became flattened so as to assume the appearance of those gas jets called 'butterfly. The plane of the 'butterfly' was parallel with the pole that I presented, or, in other words, with the section of the magnet.
I am aware that many investigators discountenance such experiments, but I believe with Venzano that the physical phenomena of mediumship cannot be, and ought not to be, considered trivial. It was the spasmodic movement of a decapitated frog that resulted in the discovery of the Voltaic Pile. Furthermore, I intend to try every other conceivable hypothesis before accepting that of the spiritists."
