But will any candid-minded person call it the highest form of intellectual development to have a clear conception of the precession of the equinoxes, or to manufacture metaphysical conundrums, whilst remaining utterly incapable of applying common sense to human affairs that demand at least an equal amount of attention?
This etheric sun-globe has a diameter of over 300,000,000,000 miles. All the planets revolve around the sun far within its atmosphere. The etheric sun-globe revolves on its axis once in about 21,000 years, and this revolution causes the precession of the equinoxes.
The introduction of the gnomon and dial into Greece advanced astronomical knowledge, since they were used to determine the equinoxes and solstices, as well as parts of the day. Meton set up a sun-dial at Athens in the year 433 B.C., but the length of the hour varied with the time of the year, since the Greeks divided the day into twelve equal parts. Hence the introduction of water-clocks instead.
They occur in all months of the year, but the greater number take place about the time of the equinoxes. The most violent ones occur at the autumnal equinox, and on an average, two or three occur every year, and sometimes one follows another at a very short interval.
"The precession of the equinoxes," said Mr Foster, "will gradually ameliorate the physical state of our planet, till the ecliptic shall again coincide with the equator, and the equal diffusion of light and heat over the whole surface of the earth typify the equal and happy existence of man, who will then have attained the final step of pure and perfect intelligence."
Much, too, as we are inclined to ridicule the astronomy of the ancients because they made the earth the centre, we should remember that they also resolved the orbits of the heavenly bodies into circular motions, discovered the precession of the equinoxes, and knew also the apparent motions of the planets and their periods.
These conditions were exactly reversed at the end of 10,500 years, through the shifting of the perihelion combined with the precession of the equinoxes, the frozen hemisphere blooming into a luxuriant garden as its seasons came round to occur at the opposite sites of the terrestrial orbit, and the vernal hemisphere subsiding simultaneously into ice-bound rigour.
The Chinese seas are usually boisterous, subject to terrible gales of wind, and especially during the equinoxes; and it was now early November. It would clearly have been to the master's advantage to carry his passengers to Yokohama, since he was paid a certain sum per day; but he would have been rash to attempt such a voyage, and it was imprudent even to attempt to reach Shanghai.
I cannot move with this precession of the equinoxes, which is preparing for us the return of some very old, I am afraid no golden era, or the commencement of some new era that must be denominated from some new metal. In this crisis I must hold my tongue or I must speak with freedom.
Then he proved that the effect ought to be a rotation of the earth's axis over a conical surface in space, exactly as the axis of a top describes a cone, if the top has a sharp point, and is set spinning and displaced from the vertical. He actually calculated the amount; and so he explained the cause of the precession of the equinoxes discovered by Hipparchus about 150 B.C.
