...than a tropical year; and it likewise follows that the equinoctial points must have a motion along' the ecliptic in a direction contrary to the order of the signs, amounting to 50" 1, in a year : for, as the sun describe: the whole ecliptic, or 360J in a year, 365d.... | |

...30), it follows from the last mentioned circumstance, that the vernal equinox must have a motion along the ecliptic in a direction contrary to the order of the signs, amounting to about 50" in a year. As it has been found that the autumnal equinox is always at the distance... | |
