الصفحة 118 - All these things considered [that is, the chemical facts he had just recited], it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, movable 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; and that these primitive particles, being solids, are incomparably harder than any porous bodies compounded of them, even so very hard as never to wear or break...
الصفحة 117 - The parts of all homogeneal hard bodies which fully touch one another, stick together very strongly. And for explaining how this may be, some have invented hooked atoms, which is begging the question...
الصفحة 1 - I am nearly persuaded that the circumstance depends upon the weight and number of the ultimate particles of the several gases ; those whose particles are lightest and single being least absorbable, and the others more, according as they increase in weight and complexity (he added in a foot-note: 'Subsequent experiment renders this conjecture less probable').
الصفحة 119 - Now by the help of these principles, all material things seem to have been composed of the hard and solid particles above mentioned, variously associated in the first creation by the counsel of an intelligent Agent.
الصفحة 2 - An enquiry into the relative weights of the ultimate particles of bodies is a subject, as far as I know, entirely new: I have lately been prosecuting this enquiry with remarkable success.
الصفحة 119 - Particles continue entire, they may compose Bodies of one and the same Nature and Texture in all Ages: But should they wear away, or break in pieces, the Nature of Things depending on them, would be changed. Water and Earth composed of old worn Particles and Fragments of Particles, would not be of the same Nature and Texture now, with Water and Earth composed of entire Particles, in the Beginning. And therefore that Nature may be lasting, the Changes of corporeal Things are to be placed only in the...
الصفحة 14 - I repeated the operation, but soon found that the watery particles were exhausted (for they make but a small part of the atmosphere). I next combined my atoms of oxygen and azote one to one; but I found in time my oxygen failed. I then threw all the remaining particles of azote into the mixture, and began to consider how the general equilibrium was to be obtained.
الصفحة 16 - Upon reconsidering this subject, it occurred to me that I had never contemplated the effect of difference of size in the particles of elastic fluids. By size I mean the hard particle at the centre and the atmosphere of heat taken together. If, for instance, there be not exactly the same number of atoms of oxygen in a given volume of air ["air...
الصفحة 16 - This hypothesis, however beautiful might be its application, had some improbable features. "We were to suppose as many distinct kinds of repulsive powers, as of gases; and, moreover, to suppose that heat was not the repulsive power in any one case; positions certainly not very probable. Besides, I found from a train of experiments, which have been published in the Manchester Memoirs...
