Page 155 - I am obliged to go out of town, and shall not bo settled in town till the end of January ; I will then see you at any time you wish. It would gratify me to be of any service to you. I wish it may be in my power. I am, sir, your obedient, humble servant, H. DAVY.
Page 102 - When any body exists in the elastic state, its ultimate particles are separated from each other to a much greater distance than in any other state; each particle occupies the centre of a comparatively large sphere, and supports its dignity by keeping all the rest, which by their gravity, or otherwise, are disposed to encroach upon it, at a respectful distance.
Page 167 - ... that the natural knowledge which has been given to the world in such abundance during the last 50 years, I may say, should remain untouched, and that no sufficient attempt should be made to convey it to the young mind growing up and obtaining its first views of these things, is to me a matter so strange, that I find it difficult to understand.
Page 14 - We took then a long glass tube, which, by a dexterous hand and the help of a lamp, was in such a manner crooked at the bottom, that the part turned up was almost parallel to the rest of the tube...
Page 110 - Having been long accustomed to make meteorological observations, and to speculate upon the nature and constitution of the atmosphere, it often struck me with wonder how a compound atmosphere, or a mixture of two or more elastic fluids, should constitute apparently a homogeneous mass, or one in all mechanical relations agreeing with a simple atmosphere.
Page 105 - No new creation or destruction of matter is within the reach of chemical agency. We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen. All the changes we can produce, consist in . separating particles that are in a state of cohesion or combination, and joining those that were previously at a distance.
Page 110 - The different sizes of the particles of elastic fluids under like circumstances of temperature and pressure being once established, it became an object to determine the relative sizes and weights together with the relative number of atoms in a given volume. This led the way to the combinations of gases, and to the number of atoms entering into such combinations, the particulars of which will be detailed more at large in the sequel.
Page 269 - Crookes (he received the honour of knighthood in 1897) occupied himself in connection with problems of public interest or as expert adviser to the Government, but, in passing, may be mentioned his work on the disposal of town sewage, his Reports on the composition and quality of daily samples of the water supplied to London from 1880 to 1906, and his services as Consulting Expert on the Ordnance Board from 1907 onwards during the period of the war. Nor should it be forgotten that the office of President...
Page 13 - New Experiments Physico-mechanical, touching the spring of the air, and its effects ; (made for the most part in a new pneumatical engine) written .... by the honourable Robert Boyle, Esq* experiment xxxvi.
Page 117 - Mr. Dalton's permanent reputation will rest upon his having discovered a simple principle, universally applicable to the facts of chemistry — in fixing the proportions in which bodies combine, and thus laying the foundation for future labours, respecting the sublime and transcendental parts of the science of corpuscular motion. His merits, in this respect, resemble those of Kepler in astronomy.
