Page 200 - ... that the principle affords us such family groups as oxygen, fluorine, chlorine, bromine, and iodine, self-arranged in that very order ; or again, nitrogen, phosphorus, arsenic, antimony, and bismuth ; when we find that it packs together in one group all the more active and soluble electro-positive elements, hydrogen, lithium, sodium, and potassium, and in another the more inert and less soluble ones — calcium, strontium, barium, and lead — and that without outraging any other system of relations,...
Page 160 - ... fixed as to throw the light from right ahead to two points abaft the beam on the port side, and of such a character as to be visible at a distance of at least two miles.
Page 130 - For this reason these lines merit a much more critical examination than has yet been given to them, for by their aid we may be able to ascertain points of great interest in other departments of science. Thus if we are ever able to acquire certain knowledge respecting the physical state of the sun and other stars, it will be by an examination of the light they emit.
Page 200 - I am a little slow to give full credence to numerical generalizations of this sort, because we are apt to find their authors either taking some liberties with the numbers themselves, or demanding a wider margin of error in the application of their principles than the precision of the experimental data renders it possible to accord, so that the result is more or less wanting in that close appliance to nature which makes all the difference between a loose analogy and a physical law ; but in this instance...
Page 269 - I was, during which there was a loud rushing noise in my ears, like steam passing out of a tea-kettle, and a feeling of constriction around the lower part of my neck as if my coat were buttoned too tightly ; my forehead was wet with perspiration, and I yawned frequently. My...
Page 194 - I think that the preceding results are all explicable on the one admission, that Person's view of the gradual liquefaction of ice is correct (Comptes Rendus, 1850, vol.
Page 130 - ... in them, show no fixed lines, their prismatic spectrum being uninterrupted from end to end, it would appear to follow that the luminous condition of our sun, whose light contains fixed lines, cannot be referred to such incandescence or ignition. At various times those who have studied this subject...
Page 286 - ... that which was obtained during the same series of years in wheat alone, whether it was grown consecutively, or in alternation with fallow. Interesting questions arose, therefore, as to the varying sources, or powers of accumulation, of nitrogen in the case of crops so characteristically differing from one another as those above referred to. It had been found that the leguminous crops, which yielded in their produce such a comparatively large amount of nitrogen over a given area of land, were...
Page 107 - ... distinctly proved. I next imagined, as others have done, that they might have originated from the water, and consequently made a close examination of numbers of vessels filled with the same fluid : in none of these could I perceive a trace of an insect, nor could I see any in any other part of the room.
Page 100 - ... and the fixed pallets are always touching, and thus allow of no detachment or loose shake ; the holes of the axes are jewelled ; the moving parts are most carefully balanced, a consequence of which is that agitation of the whole does not disturb the parts, and the telegraph works just as well when it is twisted about in the hands, or placed on board a ship or in a railway carriage, as when fixed immovably.
