If, however, the rate of rotation exceeds a certain limit, the equatorial portion of the earth could no longer cling together.
It is well known that this protuberance is due to the rotation of the earth on its axis, by which the equatorial parts bulge out by centrifugal force.
The strata should have wrinkled, so to speak, in the equatorial regions and stretched in the polar regions, if the Earth changed from a spheroid that was considerably flatter than it now is, to its present form.
The rotation period of the equatorial region of the planet itself is 10 h.
If the central mass condensed to the present size of the Sun, the Sun's equatorial velocity of rotation should now be fully 400 km.
If the planet Mercury was abandoned as a ring of nebulosity, the equatorial velocity of the remaining central mass must at that time have been in the neighborhood of 45 km.
A remarkable fact concerning the Sun is that the equatorial region rotates once around in a shorter time than the regions in higher latitudes require.
In the same way the equatorial accelerations in Jupiter and Saturn can receive simple explanation.
Professor Piazzi Smyth characterises the elevated region as cold enough at night, and stormy beyond measure in winter, when the south-wester, or equatorial upper current, produces a fearful climate.

This fraction is denominated the ellipticity of the earth,--being the excess of the equatorial over the polar diameter.
Such would be the appearances to an inhabitant of the equatorial regions.
Combining the results of various estimates, the dimensions of the terrestrial spheroid are found to be as follows: Equatorial diameter, 7925.
The ring encompasses the equatorial regions of the planet, and the planet revolves on an axis which is perpendicular to the plane of the ring in about ten and a half hours.
The nearer the conjunction comes to the node, the further the shadow will fall from the polar towards the equatorial regions.
To the inhabitants of the equatorial parts of the earth, the sun would always have appeared to move in the prime vertical, rising directly in the east, passing through the zenith at noon, and setting in the west.
So protracted an exposure to the sun's rays, especially in the equatorial regions of the moon, must occasion an excessive accumulation of heat; and so long an absence of the sun must occasion a corresponding degree of cold.
In the equatorial regions of the earth, where the twilight is short, and Venus, at her greatest elongation, appears very high above the horizon, her splendors are said to be far more conspicuous than in our latitude.
In consequence of the accumulation of matter above the equatorial regions of the earth, a body weighs less there than towards the poles, being further removed from the centre of the earth.
Still, it has been observed that, in some countries under and near the equator, constant easterly winds are found, which are no doubt identical in their cause with those that distinguish the equatorial regions of the ocean.
Mr. Du Chaillu, speaking of the superstitions of the inhabitants of Equatorial Africa, says: “The greatest curse of the whole country is the belief in sorcery or witchcraft.
Du Chaillu asserts that the Ashangos, those of Otamo, the Apossos, the Fans, and many other tribes of equatorial Africa, consider it a mark of beauty to file their front teeth in a sharp point.
The warm air, ascending from the equatorial regions, rushes to the poles to be cooled in turn, sliding over the heavy strata of cold air below.
We now encountered a variety of currents, some setting to the south-east as just mentioned, others to the east, others to the south, until finally we fell in with the great equatorial current setting to the westward.
It overhangs the equatorial calm-belt, as has been stated, and it travels north and south with it.
The equatorial belt of waters surrounding the earth, between the tropics, whose temperature is generally 80 deg.
She is at once in the equatorial calm-belt, and under the Equatorial Cloud Ring.
The wind will now die away again, and the ship will enter the second of these belts--that of equatorial calms.
Let us pause a moment, and look into this beautiful phenomenon of theEquatorial Cloud Ring, before we flit away to other seas, and are absorbed by new phenomena.
But we have had no conversation, as yet, about the Equatorial Cloud Ring.
We are making good speed through the water, but we have at length encountered our dreaded enemy, the great equatorial current, which sets, with such regularity, along this coast.
The apparatus made to revolve is a globe connected with the steam-retort by a tube which serves as one of its axes, the steam escaping from the globe through two bent tubes placed at either end of an equatorial diameter.
Presumably this is intended to refer to the entire equatorial region.
Let me inform you that some time ago Rundle sent me a letter asking me of the man who was Governor in the Equatorial Provinces.
Governor of the Equatorial Province, came to me this afternoon, and gave me his opinions on the Wadelai officers.
After years of baffling and unpromising work the converts flocked spontaneously to the new church of Equatorial Africa.
Such people as believe in their hearts that they have the courage and means to depart from the Equatorial Province will prepare to proceed to this camp as directed by the Pasha.
The final fall of theEquatorial Government resulted from the scandalous falsehoods of an Egyptian clerk and lieutenant.
This compulsory pause will be a forced extension of time to those misguided people of the Equatorial Province who may hear of our departure from Kavalli, and who may take this halt as a further grace offered to them.
To His Excellency EMIN PASHA, Governor of theEquatorial Province.
The Pasha appeared this morning at my tent and informed me that Captain Casati was not well pleased with his departure from the Equatorial Province; that he thought it was his duty to stay.
We were now beginning to relieve ourselves of the ammunition, to carry the sick refugees from the Equatorial Province.
My tent was pitched under a small branching fig-tree, which protected it from a glowing Equatorial sun, but the heat reflected from the river's face mounted up to 87 deg.
Later, Emin sent for a photograph apparatus, and receives, "I sent you to the Equatorial Provinces as governor, not as photographer.
The Company had twice before sailed eastward from the Cape, to the equatorial islands of the Indies.
Also, the cross-staff could not be used when the sun was high in the sky, which was the case in equatorial waters.
The twelve men who held the balloon by twelve cords fastened to the equatorial circle, let them slip a little between their fingers, and the balloon rose several feet higher.
The central line will strike near one pole in the first part of the series; in the equatorial regions about the middle of the series, and will leave the Earth by the other pole at the end.
It is now widely recognised that the typical Corona of the minimum of the Sun-spot cycle consists chiefly of two great equatorial streamers.

The great valley of the Magdalena, extending from the Caribbean coast to the equatorial line, is one of inexhaustible resources.
Major-general of the Ottoman Empire, late Governor-general of the Equatorial Nile Basin, &c.
Mr. Alvan Clark was commissioned to erect a larger equatorial for Washington Observatory; the object-glass (the rough disks of which were also furnished by Messrs.
It was mounted on its cast-iron equatorial stand, and at work in the field adjoining the village green at Bainbridge, Yorkshire.
He found the equatorial comparatively clumsy; he left it nearly perfect.
Besides these instruments John Jones has anequatorial which is mounted on a tripod stand, made by himself.
In 1855 Mr. Cooke obtained a silver medal at the first Paris Exhibition for a six-inch equatorial telescope.
A few years later he was invited to Osborne by the late Prince Albert, to discuss with his Royal Highness the particulars of an equatorial mounting with a clock movement, for which he subsequently received the order.
I mounted it in a wooden tube, placed it on a wooden stand, and used it for a time thus mounted; but getting disgusted with the tremor and inconvenience I had to put up with, I resolved to construct for it an iron equatorial stand.
The other region, called by Rudolph theEquatorial District, lies a little further to the east on both sides of the equator in long.
Whymper, who ascended the mountain, says: "When the transparency of the air is increased and its enormous circular summit is seen projected upon the deep azure of blue of the Equatorial sky, it represents a magnificent sight.
Volcanoes are to be found in practically all parts of the earth, not only in the equatorial regions, where they are especially numerous, but also in the frigid and temperate zones.
Mr. Crommelin undertakes the altazimuth and Sheepshanks equatorial reductions, and Mr. Bryant the transit and meridian zenith distance reductions and time-determinations.
In the German or Fraunhofer form of mounting for an equatorial there is but a single pillar, which carries a comparatively short polar axis.
It was first intended to be mounted as an altazimuth, but proved to be unsteady in that position, and was then converted into an equatorial without clockwork, and mounted in its present position.
The Astronomer Royal, therefore, soon after the completion of the great equatorial of 28-inches aperture placed in the south-east dome, added this work to the Observatory programme.
