Page 83 - 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?
Page 85 - 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 proportions to space, as most conduced to the end for which He formed them...
Page 86 - ... to derive two or three general principles of motion from phenomena, and afterwards to tell us how the properties and actions of all corporeal things follow from those manifest principles, would be a very great step in philosophy, though the causes of those principles were not yet discovered: and therefore I scruple not to propose the principles of motion above mentioned, they being of very general extent, and leave their causes to be found out.
Page 218 - D'Alembert, was the Precession of the equinoxes and the Nutation of the earth's axis, according to the theory of gravitation.
Page 84 - In explaining the structure of solid bodies, he is of opinion, " 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...
Page 83 - For it's well known, that Bodies act one upon another by the Attractions of Gravity, Magnetism, and Electricity; and these instances shew the Tenor and Course of Nature, and make it not improbable but that there may be more attractive Powers than these.
Page 320 - All the recent works relating to Mineralogy, Geology, Conchology, and Chemistry ; also Geological Maps, Models, Diagrams, Hammers, Blowpipes, Magnifying Glasses, Platina Spoons, Electrometer and Magnetic Needle, Glass-top Boxes, Microscopic Objects, Acid Bottles, Sec., can be supplied to the Student in these interesting and Important branches of Science.
Page 83 - What I call Attraction may be perform'd by impulse, or by some other means unknown to me. I use that Word here to signify only in general any Force by which Bodies tend towards one another, whatsoever be the Cause.

Page 129 - ME Becquerel at the bottom of the list of diamagnetic substances. This gas is allowed to be upon the turning-point between the paramagnetic and diamagnetic Classes. But magnetism is so liable to extinction under the influence of heat, that the magnetism of a metal may very possibly disappear entirely when it is fused or vaporized, as appears with hydrogen in the form of gas.
