Page 146 - A silk thread in a known electric state, thus indicates the kind of electricity possessed by other substances : a convenient mode of doing this is to draw a thread of white silk rapidly through a fold of coarse brown paper, previously warmed, by which means its whole length will be rendered positive.
Page 145 - ... inferred that there are two kinds or states of electricity, one termed vitreous, because developed on glass, and the other resinous electricity, from being first noticed on resinous substances. These two kinds of electricity, one or other of which is possessed by every electrified substance, are also termed positive and negative, the terms vitreous and positive being used synonymously, as are resinous and negative...
Page 153 - I do not know) he put some brass filings. At the top of this rod a thread was fastened, which hung down by the side of the rod when it was not electrified ; but when it was, it avoided the rod, and stood at a distance from it, making an angle at the place where it was fastened. To measure this angle, he had the arch of a quadrant fastened to the bottom of the iron rod.
Page 154 - ... much hurt. The latter could give no particular account of the way in which he was affected ; for at the time the professor was struck, he stated that there arose a sort of steam or vapor which entirely benumbed him, and made him sink down to the ground, so that he did not even hear the clap of thunder, which was very loud.

Page 154 - ... it, accompanied by Mr. Solokow (an engraver, whom he frequently took with him, to be a joint observer of his electrical experiments, in order to represent them the better in cuts) when this gentleman, who was standing close to his elbow, observed a globe of blue fire, as he called it, as big as his fist, jump from the rod of the gnomon towards the head of the professor, which was, at that instant, at about a foot distance from the rod.
Page 144 - Amber was drawn gently and slightly thro' the Cloath, it produc'da light but no Crackling; but by holding one's Finger at a little distance from the Amber, a large Crackling is...
Page 153 - The professor had provided himself with an instrument which he called an 'electrical gnomon,' the use of which was to measure the strength of electricity. It consisted of a rod of metal terminating in a small glass vessel, into which (for what reason I do not know) he put some brass filings. At the top of this rod a thread was fastened, which hung down by the side of the rod when it was not electrified ; but when it was, it avoided the rod, and stood at a distance from it, making an angle at the...
Page 151 - Because, as we have shown by the magnets, the outward current of the body charged plus present its positive end. — But a body in a minus state has an inward current .of electricity, which it attracts from contiguous substances. Of course the negative end of the ultimate particles of this inward current is presented. And what is the consequence ? Why two bodies, the one having an outward, and the other an inward current, present opposite polarities to each other, and are attracted from the operation...
