Página 39 - They present not a dead mass of dull monotonous red ; but an endless variety of bright and living hues, from the deepest crimson to the softest .pink, verging also sometimes to orange and yellow. These varying shades are often distinctly marked by waving lines, imparting to the surface of the rock a succession of brilliant and changing teints, like the hues of watered silk, and adding greatly to the imposing effect of the sculptured monuments.
Página 173 - Professor Mather, who observed the barometer at Copper Harbour during one of these fluctuations, remarks : — ' As a general thing, fluctuations in the barometer accompanied fluctuations in the level of the water ; but sometimes the water-level varied rapidly in the harbour, while no such variations occurred in the barometer at the place of observation.' * " As a general rule, these variations in the water-level indicate the approach of a storm, or a disturbed state of the atmosphere. The barometer...
Página 128 - With the same view he had doubtless caused Nilometers to be fixed at Assuan and other suitable places ; for without a comparison with these, the observations at Semne could be of little use. " The highest rise of the Nile in each year at Semne, was registered by a mark, indicating the year of the king's reign, cut in the granite, either on one of the blocks forming the foundation of the fortress, or on the cliff, and particularly on the east or right bank, as best adapted for the purpose. Of these...

Página 303 - During the height of the gale (March 6lh) the form of the waves was less regular than after the wind had, for some time, begun to subside. Though in many cases when the sea was highest the succession of the primary waves was perfectly distinct, it was rather difficult to trace an identical ridge for more than a quarter to a third of a mile. The grand elevation in such case sometimes extended by a straight ridge or was sometimes bent as of a crescent form, with the central mass of water higher than...
Página 281 - ... struggled to find something new among the arithmetical relations of the planetary elements. Between every two adjacent planets there is a point where their attractions are equal. If we call the distance of this point from the Sun the radius of a planet's sphere of attraction, then Mr Kirkwood's law is, that in every planet the square of the length of its year, reckoned in days, varies as the cube of the radius of its sphere of attraction.
Página 165 - While we have in the law of Kepler a bond of mutual relationship between the planets, as regards their revolutions around the sun, it is remarkable that no law regulating their rotations on their axes has ever been discovered. For several years I have had little doubt of the existence of such a law in nature, and have been engaged, as circumstances would permit, in attempting its development.
