sinking; declension; degradation. Oblique descension (Astron.), the degree or arc of the equator which descends, with a celestial object, below the horizon of an oblique sphere. -- Right descension, the degree or arc of the equator which descends below the horizon of a right sphere at the same time with the object.

A great circle drawn on a terrestrial globe, making an angle of 23º 28' with the equator; -- used for illustrating and solving astronomical problems.

a sphere; especially, in reference to the figure of the earth, the difference between the equatorial and polar semidiameters, divided by the equatorial; thus, the ellipticity of the earth is

t or the center of ann epicycle was conceived to move uniformly; -- called also eccentric equator.

Pertaining to the regions or climate of the equinoctial line or equator; in or near that line; as, equinoctial heat; an equinoctial sun.

the angle included between the radius of the earth through the place and the plane of the equator, in distinction from geographic latitude. It is a little less than the geographic latitude.

icular or normal to the level surface of water at rest at the place, and the plane of the equator; differing slightly from the geocentric latitude by reason of the difference between the earth's figure and a true sphere. -- Geographical mile.

(b) A circle upon an equatorial telescope lying parallel to the plane of the earth's…

The angle made by two lines or planes; as, the inclination of the plane of the earth's equator to the plane of the ecliptic is about 23º 28'; the inclination of two rays of light.

A branch of the equatorial current of the Pacific, washing the eastern coast of Formosa and thence flowing northeastward past Japan and merging into the easterly drift of the North Pacific; -- called also Kuro-Siwo, or Black Stream, in allusion to the deep blue of its water.

Distance north or south of the equator, measured on a meridian.

The equator; -- usually called the line, or equinoctial line; as, to cross the line.

The arc or portion of the equator intersected between the meridian of a given place and the meridian of some other place from which longitude is reckoned, as from Greenwich, England, or sometimes from the capital of a country, as from Washington or Paris. The longitude of a place is expressed either in degrees or in ti…

Near, or not very distant from, the equator; as, in the low northern latitudes.
