Page 125 - ... this operation it will be found that the results are sometimes more and sometimes less satisfactory, in consequence of small and accidental variations in the proportions employed. It happens sometimes that the chloride of silver is disposed to darken of itself, without any exposure to light : this shows that the attempt to give it sensibility has been carried too far. The object is to approach to this condition as near as possible without reaching it, so that the substance may be in a state ready...
Page 349 - Mrs. Marcet's Conversations on Vegetable Physiology ; comprehending the Elements of Botany, with their Application to Agriculture.
Page 343 - By exposure to excessive cold the primitive fungi are killed, but their seed still retains vitality, and, if immersed in snow, which appears to be their native soil, they reproduce new fungi, which are generally of a red colour. The Philosophical Transactions for 1823 contains the paper by Mr. Bauer already alluded to, entitled " Microscopical Observations on the Suspension of the Muscular Motions of the Vibrio tritici," which forms the Croonian Lecture for that year.
Page 203 - April 22, 1663, constituted them a body politic and corporate, by the appellation of the President, Council, and Fellows of the Royal Society of London, for improving Natural Knowledge.
Page 389 - On the Transparency of the Atmosphere, and the Law of Extinction of the Solar Rays in passing through it," published in the Philosophical Transactions for 1842.
Page 125 - We shall find (especially if the paper has been kept some weeks before the trial is made) that its sensibility is greatly diminished, and, in some cases, seems quite extinct. But if it is again washed with a liberal quantity of the solution of silver, it becomes again sensible to light, and even more so than it was at first. In this way, by alternately washing the paper with salt and silver, and drying it between times, I have succeeded in increasing its sensibility to the degree that is requisite...
Page 312 - Dry the paper cautiously at a distant fire, or else let it dry spontaneously in a dark room. When dry, or nearly so, dip it into a solution of iodide of potassium, containing 500 grains of that salt dissolved in one pint of water, and let it stay two or three minutes in the solution.
Page 394 - Besides these, he also observed that the rays which are effective in destroying a given tint, are, in a great many cases, those whose union produces a colour complementary to the tint destroyed, or at least one belonging to that class of colours to which such complementary tint may be referred.
Page 336 - ... or in other words the force of the current is equal to the sum of the electro-motive forces divided by the sum of the resistances.
Page 339 - The strength of a pillar, with one end rounded and the other flat, is the arithmetical mean between that of a pillar of the same dimensions with both ends round, and one with both ends flat. Thus, of three cylindrical pillars, all of the same length and diameter, the first having both its ends rounded, the second with one end rounded and one flat, and the third with both ends flat, the strengths are as 1, 2, 3, nearly.
