Pagina 462 - The ox-gullet, or cell, is now nearly filled with a concentrated solution of common salt, to which a few drops of hydrochloric acid have been added, and the...
Pagina 504 - ... 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 241 - 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 one-tenth of oil of vitriol.
Pagina 12 - 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 439 - The notion of the gravitating force is, with those who admit Newton's law, but go with him no further, that matter attracts matter with a strength which is inversely as the square of the distance. Consider, then, a mass of matter (or a particle), for which present purpose the sun will serve, and consider a globe like one of the planets, as our earth, either created or taken from distant space and placed near the sun as our earth is ; — the attraction of gravity is then exerted, and we say that...
Pagina 439 - 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 125 - ... consumed by a given weight of animal, within a given time, and the amount of increase obtained from a given weight of food.
Pagina 440 - ... then can that power arise by their mere approximation or co-existence? That a body without force should raise up force in a body at a distance from it, is too hard to imagine ; but it is harder still, if that can be possible, to accept the idea when we consider that it includes the creation of force.
Pagina 438 - Res. 3164, &c.) The steel sphere was then magnetized in the direction of its axis, and was found to be so hard as to retain its own magnetic state when in a reverse direction between the poles of the dominant magnet, for upon its removal its magnetism remained unchanged. Experiments were then made in a selected position, where the dominant magnetic force was not too strong — (a magnet able to lift 430 Ibs.
Pagina 439 - It is, probably, of great importance that our thoughts should be stirred up at this time to a reconsideration of the general nature of physical force, and especially to those forms of it which are concerned in actions at a distance.
