Pagina 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...
Pagina 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?
Pagina 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...

Pagina 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.
Pagina 605 - ... 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...
