Сторінка 338 - Subtract the loss of the heavy body weighed by itself in water, previously known, from the loss sustained by the combined solids. The remainder will be the weight of as much water as is equal in bulk to the lighter body.
Сторінка 338 - This result gives the weight of a bulk of water equal to that of the specimen, and by dividing the weight of the specimen in air by this number, the specific gravity is obtained.
Сторінка 346 - I have endeavoured to account for, are explicable by the motion, bigness, gravity, shape, and other mechanical affections of the small parts of liquors, I have done what I pretended; which was not to prove, that no angel or other immaterial creature could interpose in these cases; for concerning such agents, all that I need say, is, that in the cases proposed we have no need to recur to them.
Сторінка 238 - And the more wonderful things he discovers in the works of nature, the more auxiliary proofs he meets with to establish and enforce the argument, drawn from the universe and its parts, to evince that there is a God ; which is a proposition of that vast weight and importance, that it ought to endear every thing to us that is able to confirm it, and afford us new motives to acknowledge and adore the divine Author of things.
Сторінка 111 - I must freely observe that, to speak properly, a law being but a notional rule of acting according to the declared will of a superior, it is plain that nothing but an intellectual being can be properly capable of receiving and acting by a law.
Сторінка 243 - I look upon a law as a moral, not a physical cause, as being indeed but a notional thing, according to which, an intelligent and free agent is bound to regulate its actions.
Сторінка 662 - ... pressure of a mercurial cylinder of about 29 inches, as we are taught by the Torricellian experiment; so here the same air being brought to a degree of density about twice as great as that it had before, obtains a spring twice as strong as formerly. As may appear by its being able to sustain or resist a cylinder of 29 inches in the longer tube, together with the weight of the atmospherical cylinder that leaned upon those 29 inches of mercury; and, as we just now inferred from the Torricellian...
Сторінка 464 - Drebell conceived, that it is not the whole body of the air, but a certain quintessence (as Chymists speak) or spirituous part of it, that makes it fit for respiration...
Сторінка 238 - ... instrument consists; and having separately considered the figure, size, consistence, texture, diaphaneity or opacity, situation, and connection of each of them, and their coaptation in the whole eye, shall discover, by the help of the laws of optics, how admirably this little organ is fitted to receive the incident beams of light, and dispose them in the best manner possible for completing the lively representation of the almost infinitely various objects of sight.
Сторінка 106 - ... and speak after the manner of true and positive beings, of such things as are but chimerical, and some of them negations or privations themselves ; as death, ignorance, blindness, and the like. It concerns us therefore to stand very carefully upon our guard, that we be not insensibly misled by such an innate and unheeded temptation to error, as we bring into the world with us («).
