Side 453 - ... 2. But, if the persons on wax touch one another during the exciting of the tube, neither of them will appear to be electrised. 3. If they touch one another after exciting the tube, and drawing the fire as aforesaid, there will be a stronger spark between them, than was between either of them and the person on the floor.
Side 453 - C, standing on the floor, both appear to be electrised: for he having only the middle quantity of electrical fire, receives a spark upon approaching B, who has an over quantity; but gives one to A, who has an under quantity. If A and B approach to touch each other, the spark is stronger, because the difference between them is greater: After such touch there is no spark between either of them and C, because the electrical fire in all is reduced to the original equality.
Side 453 - ... a person standing on the floor; that is, he will perceive a spark on approaching each of them with his knuckle. 2. But, if the persons on wax touch one another during the exciting of the tube, neither of them will appear to be electrised.
Side 453 - B (who stands on wax likewise), passing his knuckle along near the tube, receives the fire which was collected by the glass from A; and his communication with the common stock being likewise cut off, he retains the additional quantity received. To C, standing on the floor, both appear to be...
Side 453 - These appearances we attempt to account for thus: We suppose, as aforesaid, that electrical fire is a common element, of which every one of the three persons above mentioned has his equal share, before any operation is begun with the tube.
Side 559 - An Essay on Quantity, occasioned by reading a Treatise, in which Simple and Compound Ratios are applied to Virtue and Merit...
Side 453 - To electrize plus or minus, no more needs to be known than this, that the parts of the tube or sphere that are rubbed, do, in the instant of the friction, attract the electrical fire, and therefore take it from the thing rubbing; the same parts immediately, as the friction upon them ceases, are disposed to give the fire they have received to any body that has less.
Side 564 - Several other things might be advanced to show, that this definition agrees best with the common popular notion of the word force. If two bodies meet directly with a shock, which mutually destroys their motion without producing any other sensible effect, the vulgar would pronounce, without hesitation, that they met with equal force ; and so they do, according to the measure of force above laid down : for we find by experience, that in this case their velocities are reciprocally as their quantities...
Side 685 - ... become less, their periodical times will also be diminished. Thus in time the earth ought to come within the region of Venus, and in fine into that of Mercury, where it would necessarily be burnt. Hence it is manifest that the system of the planets cannot last for ever in its present state.
