There will be five eclipses this year, three of the Sun and two of the Moon, as follows:

I. Total of the Moon Feb. 8–9, visible, generally on the evening of the 8th and morning of the 9th throughout the United States. The follow il); is the star, dard time of the different phases:

The size of this coclipse is i8.57 digits, the Moon's diameter being takon as 12 digits. This is measured on a line at right angles to the arrow from d, the Inliddlo point, and downward, or south, in this case because the Moon passes below the centre of the shadow. The circles at 1 and 2 show how the Moon will appear when the first and last six digits are eclipsed. The total phase will begin at c and end at e. Hold the cut so the north point will be toward the North Star and lock upward at the figure to have it natural.

A8’s RONOMICAL, 11 figures... in the table “Sidereal noon” following this note. Note whether the figures be

“Morn” or “Eve.” If “Morn” and the sum is more than 12 hours, the result will be ||

eyening of the same day; if ‘‘Eve,” and the sum is more than 12 hours, the result will be morning of the next day. Having found the time of meridian passage, for

the rising subtract and for the setting add the numbers opposite the name of the star ||

in the coloumn headed “For rising and setting,” observing the directions as to “Morn”

and “Eve,” as given above. Those stars marked — in the last column are eircum- || polar and do not rise or set in the latitude of New-York City. Stars having an ||

asterisk (*) in the last column are only to be seen in the far south and when near the meridian, as the vapors of the horizon will obscure them at rising or 88tting.

To tell how high up from the nearest point of the horizon a star will be at its is meridian passage, subtract the declination of the star from 90°, and if the result 18 &

less than the latitude of the place of the observer that star will neither rise nor Set,

but is circumpolar, and the difference between that result and the latitude shows the

star's altitude above the north point of the horizon or below the southern horizon.

Or, (90° — dec.) —latitude = altitude or elevation of the star above the nearest point

of the horizon at meridian passage for stars of a south deemination. Examples:

Sidereal noon, November 5. . . . . . . . . . . . . 9 Q3 p. m.

351 p. m. = Time of rising. 11 51 p. m. = Time of setting.

When the declination of a star is such as to bring it nearer to the zenith than to the

tude, such difference is to be counted northward (otherwise southward) from zenith. SATDTERIEAFL NOON.
