Page 268 - Subterranea," he speaks of the chemists as a strange class of mortals, impelled by an almost insane impulse to seek their pleasure among smoke and vapour, soot and flame, poisons and poverty. ' Yet among all these evils,' he says, ' I seem to myself to live so sweetly, that may I die if I would change places with the Persian king.
Page 295 - I at first laid down, namely, that the chemical power of a current of electricity is in direct proportion to the absolute quantity of electricity which passes (377, 783).
Page 56 - When we consider how simple the law of refraction is (that the ratio of the sines of the angles of incidence and refraction is constant for the same medium...
Page 195 - Thus, the whole force of the bottle and power of giving a shock is in the glass itself; the nonelectrics in contact with the two surfaces serving only to give and receive to and from the several parts of the glass ; that is, to give on one side and take away from the other.
Page 298 - I have referred to above, would be necessary to supply electricity sufficient to decompose a single grain of water; or, if I am right, to equal the quantity of electricity which is naturally associated with the elements of that grain of water, endowing them with their mutual chemical affinity.
Page 555 - Was bid turn reins from the equinoctial road Like distant breadth to Taurus with the seven Atlantic Sisters, and the Spartan Twins, Up to the Tropic Crab; thence down amain By Leo, and the V1rgin, and the Scales, As deep as Capricorn; to bring in change Of seasons to each clime; else had the spring Perpetual smiled on earth with verdant flowers, Equal in days and nights...
Page 276 - Physique, and to evade the influence which this gave him, the antiphlogistians' established, as the vehicle of their opinions, another periodical, the Annales de Chimie. In England, indeed, their success was not so immediate. Cavendish,* in his Memoir of 1784, speaks of the question between the two opinions as doubtful. " There are," he says, " several Memoirs of M. Lavoisier, in which he entirely discards phlogiston; and as not only the foregoing experiments, but most other phenomena of nature,...
Page 76 - ... said that the angle of reflection from transparent bodies, which most completely polarizes the reflected ray, does not follow any discoverable rule with regard to the order of refractive or dispersive powers of the substances. Yet the rule was in reality very simple. In 1815, Sir D. Brewster stated6 as the law, which in all cases determines this angle, that " the index of refraction is the tangent of the angle of polarization.
Page 570 - Some selection of one of these forms of the hypothesis, rather than the others, with evidence for the selection, is requisite to entitle us to place it among the known causes of change, which in this chapter we are considering. The bare conviction that a creation of species has taken place, whether once or many times, so long as it is unconnected with our organical sciences, is a tenet of Natural Theology rather than of Physical Philosophy.
Page 313 - Nature does not employ all figures, but only certain ones of those which are possible ; and of these, the determination is not to be fetched from the brain, or proved a priori, but obtained by experiments and observations.
