In drawing the figures of the twelve celestial signs, one is represented larger and the next smaller, proceeding from the centre. Into the back of the drum, in the middle, a revolving axis is inserted, and round that axis is wound a flexible bronze chain, at one end of which hangs the "cork" which is raised by the water, and at the other a counterpoise of sand, equal in weight to the "cork."
The whine of power at emergency levels began. The Darzent force had screen detectors, because they stopped at once and turned back to their ship. Short, sharp rocket blasts shot out from the bow tubes of the ship, as it turned on its axis to attack the force screen. "Let's get going," Thane said. "We all can't go," Pyuf pointed out.
A deer as large as the Axis, but differing from it in the number and arrangement of its spots, has been described by Dr. Kelaart, to whose vigilance the natural history of Ceylon is indebted, amongst others, for the identification of two new species of monkeys , a number of curious shrews , and an orange-coloured ichneumon , before unknown. Faun.
In the last chapter it was explained that the heated atmosphere at the equator rises, and that the cooler atmosphere from the poles rushes in to supply its place. That which rushes from the south pole is, of course, a south wind, that from the north pole a north wind; but, owing to the Earth's motion on its axis from west to east, the one becomes a north-east, the other a south-east wind.
It was odd how the word seemed to shape the act, though one knew how ancillary it really was. As he talked, it was as if the globe had swung around, and he himself were upright on its axis, with Mr. Spence underneath, on his head.
Grote, that the diurnal rotation of the earth on its axis and the revolution of the sun and outer heaven precisely coincide, it would be difficult to imagine that Plato was unaware of the consequence.
Approaching it carefully, Seaton deftly guided the projector lengthwise into that hollow receptacle and anchored it in the exact optical axis.
We must admit, further, that Aristotle attributed to Plato the doctrine of the rotation of the earth on its axis. On the other hand it has been urged that if the earth goes round with the outer heaven and sun in twenty-four hours, there is no way of accounting for the alternation of day and night; since the equal motion of the earth and sun would have the effect of absolute immobility.
It will be remembered that it was night on this side of Mars when we went down, but our adventure had occupied several hours, and now Mars had so far turned upon its axis that the portion of its surface over which we were had come around into the sunlight.
For current indicators, a pivoted or suspended copper band or ring composed of thin washers piled together and insulated from one another, and made to carry a pointer or index has been placed in the axis of a coil conveying alternating currents whose amount or potential is to be indicated.
