第 19 頁 - On the Power, Wisdom, and Goodness of God as manifested in the Adaptation of External Nature to the Moral and Intellectual Constitution of Man.
第 iii 頁 - Society answerable, for the certainty of the facts, or propriety of the reasonings, contained in the several Papers so published, - which must still rest on the credit or judgment of their respective Authors.
第 202 頁 - This will cause the air at the equator to stand more than seven miles higher from the surface of the earth to the top of the atmosphere than at the north pole.
第 373 頁 - It being thus established that the mind perceives an object of three dimensions by means of the two dissimilar pictures projected by it on the two retinae, the following question occurs: What would be the visual effect of simultaneously presenting to each eye, instead of the object itself, its projection on a plane surface as it appears to that eye?
第 5 頁 - I went into the cube and lived in it, and using lighted candles, electrometers, and all other tests of electrical states,. I could not find the least influence upon them, or indication of anything particular given by them, though all the time the outside of the cube was powerfully charged, and large sparks and brushes were darting off from every part of its outer surface.
第 156 頁 - The word current is so expressive in common language that when applied in the consideration of electrical phenomena, we can hardly divest it sufficiently of its meaning, or prevent our minds from being prejudiced by it.
第 4 頁 - Another ever-present question on my mind has been, whether electricity has an actual and independent existence as a fluid or fluids, or was a mere power of matter, like what we conceive of the attraction of gravitation.
第 375 頁 - D', which may thus be removed to different distances from the mirrors. In most of the experiments hereafter to be detailed, it is necessary that each upright board shall be at the same distance from the mirror which is opposite to it. To facilitate this double adjustment, I employ a right- and a left-handed wooden screw, r I ; the two ends of this compound screw pass through the nuts...
第 101 頁 - Interval v 0'62 of an inch. 1386. On proceeding to experiment it was found that when air or any gas was in the receiver a, the interval u was not a fixed one ; it might be altered through a certain range of distance, and yet sparks pass either there or at v in the receiver. The extremes were therefore noted, ie the greatest distance short of that at which the discharge always took place at v in the gas, and the least distance short of that at which it always took place at u in the air. Thus, with...
