Сторінка 63 - And therefore that Nature may be lasting, the Changes of corporeal Things are to be placed only in the various Separations and new Associations and Motions of these permanent Particles : compound Bodies being apt to break, not in the midst of solid Particles, but where those particles are laid together and only touch in a few Points.
Сторінка 63 - All these things being considered, it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties and in such proportion to space as most conduced to the end for which he formed them...
Сторінка 59 - Have not the small particles of bodies certain powers, virtues, or forces by which they act at a distance, not only upon the rays of light for reflecting, refracting, and inflecting them, but also upon one another for producing a great part of the phenomena of nature?
Сторінка 58 - And, in reasoning on this subject, we must not forget to consider that most remarkable circumstance, that the source of heat generated by friction, in these experiments, appeared evidently to be inexhaustible. It is hardly necessary to add, that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance: and it appears to me to be extremely difficult...
Сторінка 62 - ... that the smallest particles of matter may cohere by the strongest attractions, and compose bigger particles of weaker virtue; and many of these may cohere and compose bigger particles whose virtue is still weaker ; and so on for divers successions, until the progression end in the biggest particles, on which the operations in chemistry, and the colours of natural bodies, depend, and which, by adhering, compose bodies of a sensible magnitude.
Сторінка 535 - ... a powerful everliving Agent, who, being in all places, is more able by his will to move the bodies within hie. boundless uniform sensorium, and thereby to form and reform the parts of the universe, than we are by our will to move the parts of our own bodies.
Сторінка 58 - It is hardly necessary to add that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner the Heat was excited and communicated in these experiments, except it be MOTION.
Сторінка 63 - For it became him who created them to set them in order. And if he did so, it's unphilosophical to seek for any other Origin of the World, or to pretend that it might arise out of a Chaos by the mere Laws of Nature; though being once form'd, it may continue by those Laws for many Ages.
Сторінка 603 - ... by the help of the fat of hogs, has covered the whole with flour, laid on by a machine with the utmost regularity ; if, when thus attired, he issues forth, and meets a Cherokee Indian, who has bestowed as much time at his toilet, and laid on...
Сторінка 58 - ... the particles move round their own axes, and separate from each other, penetrating in right lines through space.
