Сторінка 143 - Differences of Latitude and the Departures to every Minute of the Quadrant and to Five Places of Decimals. Together with a Table of the lengths of each Degree of Latitude and corresponding Degree of Longitude from the Equator to the Poles ; with other Tables useful to the Surveyor and Engineer.
Сторінка 386 - The figures for the last five years are given in the following table, from which it will be seen that there has been a considerable expansion in the output during the period covered : Building Materials 1899 to 1903 Material.
Сторінка 323 - On the Distribution of Strain in the Earth's Crust resulting from Secular Cooling; with special reference to the growth of continents and the formation of mountain chains.
Сторінка 128 - We may consider that the structure of a chemical element is more complicated than has hitherto been supposed. Between the molecules we are accustomed to deal with in chemical reactions and ultimate atoms as first created, come smaller molecules or aggregates of physical atoms ; then sub-molecules differ one from the .other, according to the position they occupied in the yttrium edifice.
Сторінка 139 - Tropical and extra- tropical cyclones are identical in general character, but differ in certain details, due to latitude, surrounding pressure, and to the relative intensity of rotation or translation. III. "A Thermal Telephone Transmitter.
Сторінка 101 - The spectroscope shows broad interference bands in the transmitted light, which change their position on altering the angle of incidence of the light which passes through the cuticle. Precisely similar colours, metallic on reflection, non-metallic and with the complementary tints on transmission, with the same spectroscopic appearances and changes induced by the same means, are seen in the surface films which are formed on bottle glass after prolonged exposure to earth and moisture. In the alternating...
Сторінка 351 - Darwin, in his investigation of the equilibrium of a rotating mass of fluid, found, in accordance with the independent researches of Poincare, that when a portion of the central body becomes detached through increasing angular velocity, the portion should bear a far larger ratio to the remainder than is observed in the planets and satellites of the solar system, even taking into account heterogeneity from the condensation of the parent mass. Now this state of things, in which the masses though not...
Сторінка 81 - TAKE the simplest case : let the moving solid be a globe, and let the fluid be of infinite extent in all directions. Let its pressure be of any given value, P, at infinite distances from the globe, and let the globe be kept moving with a given constant velocity, V. If the fluid keeps everywhere in contact with the globe, its velocity relatively to the globe at the equator (which is the place of greatest relative velocity) is f F.
Сторінка 365 - ... Whenever the main current passed, the small battery was found to send a steady current which could be measured. The smallest electromotive force which was observed to send a current under these conditions was one-sixth of a Leclanche. An electromotive force of one-sixth of a Leclanche is about onequarter of a volt, and a current has thus been obtained in a gas from an electromotive force which could not maintain a current through water. An electromotive force of O'l volt gave doubtful results,...
Сторінка 137 - ... transitional forms of rotating air. The general circulation of a cyclone, as shown by the motion of the clouds, appears to be the same everywhere. All over the world, unusual coloration of the sky at sunrise and sunset is observed, not only before the barometer has begun to fall at any place, but before the existence of any depression can be traced in the neighbourhood. Cirrus appears all round the cloud area of a tropical cyclone, instead of only round the front semicircle, as in higher latitudes....
