Pàgina 35 - That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to. another, is to me so great an absurdity that I believe no man, who has iu philosophical matters a competent faculty of thinking, can ever fall into it.
Pàgina 35 - It is inconceivable, that inanimate brute matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact; as it must do, if gravitation, in the sense of Epicurus, be essential and inherent in it.
Pàgina 9 - ... ascertaining whether the action would take place through such a medium, and in case it did, as it was thought at the time, of demonstrating that the action could not arise from metal vapour. The experiment was quite successful ; the photographic plate, notwithstanding the varnish, was strongly acted on. The experiment was repeated several times, and always with the same result ; but the pictures seemed rather too good, darker than those given by the zinc alone, and on trying the copal on plain...

Pàgina 20 - ... combinations and separations of all simple bodies are conducted in a definite and invariable ratio of relative weight or measure *; as that of one part to one part, one part to two parts, one to three, or one to four; and, consequently, that every change in the compound thus produced, whether of addition or diminution, is a precise multiple or divisor of such ratio ; or, in other words, that...
Pàgina 33 - ... philosophers, that all circumterrestrial bodies gravitate towards the earth. That no bodies really light are to be found, is now confirmed by manifold experience. That which is relative levity is not true levity, but apparent only; and arises from the preponderating gravity of the contiguous bodies. Moreover, as all bodies gravitate towards the earth, so does the earth again towards bodies. That the action of gravity is mutual, and equal on both sides, is thus proved. Let the mass of the earth...
Pàgina 19 - that which doth assign unto each thing the kind, — that which moderates the force and power, — that which doth appoint the form and manner of work ; it is, in truth, one established and constant mode or process and fixed correspondence between cause and effect.
