Pagina 435 - ... the mind. The second sub-case, or that of a new or another form of power, is also one which has never been imagined by others, in association with the theory of gravity. I made some endeavours, experimentally, to connect gravity with electricity, having this very object in view (Phil. Trans. 1851, p. 1) ; but the results were entirely negative. The view, if held for a moment, would imply that not merely the sun, but all matter, whatever its state, would have extra powers set up in it, if removed...
Pagina 119 - ... consumed by a given weight of animal, within a given time, and the amount of increase obtained from a given weight of food. The results, which formed the subject of the present communication, afforded further illustration of some of the points brought forward...
Pagina 434 - ... rendered existent without action or without its equivalent action. The conservation of power is now a thought deeply impressed upon the minds of philosophic men ; and I think that, as a body, they admit that the creation or annihilation of force is equally impossible with the creation or annihilation of matter. But if we conceive the sun existing alone in space, exerting no force of gravitation exterior to it ; and then conceive another sphere in space having like conditions, and that the two...
Pagina 498 - ... the back courts and mews-lanes of large cities, all the impurities being absorbed and retained by the charcoal, while a current of pure air alone is admitted into the neighbouring apartments. In this way pure air is obtained from exceedingly impure sources.
Pagina 6 - The double chloride becomes fixed, and the vapors cease. A small number of elements (two are all that are absolutely necessary) will suffice for the decomposition of the double chloride, which presents but little resistance to electricity. The platinum plate is removed when it is sufficiently charged with the metallic deposit. It is suffered to cool, the saline mass is rapidly broken off, and the plate replaced in the current.
Pagina 433 - That gravity should be innate, inherent, and essential to matter, so that one body can 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 in philosophical matters a competent faculty of thinking can ever...
Pagina 434 - ... both are supposed to rise from a previously inert to a powerful state. On their dissociation they, by the assumption, pass into the powerless state again, and this would be equivalent to the annihilation of force. It will be easily understood, that the case of the sun...
Pagina 237 - Each salt is dissolved in its prescribed quantity of water, and the solutions are then mixed ; thereupon a precipitate is thrown down, which is either dissolved by agitation alone, or by the addition of a little cyanide of potassium ; indeed it does not much matter if the solution be a little troubled. After the addition of 250 parts of distilled water, it is subjected to the action of two Bunsen elements charged with concentrated nitric acid mixed with l-10th of oil of vitriol.
