ECLIPSES IN 1848.

In the year 1848, there will be six eclipses; four of the Sun, and two of the Moon, and a Transit of Mercury. One of the solar eclipses, one of the lunar eclipses, and the transit of Mercury will be visible in the United States.

I. Sunday, March 5th. A partial eclipse of the Sun, visible in the Northern portion of the United States.

Beginning of the general eclipse, 7h. 14.9m. M. [Mean Time at Washington] in latitude 47° 35' N., and longitude 86° 28′ W. of Greenwich. Greatest obscuration on the earth, 8h. 22.9m. M. in latitude 71° 53' N. and longitude 91° 44′ W. of Greenwich.

End of the general eclipse, 9h. 30.8m. M. in latitude 80° 26 N. and longitude 16° 5' E. of Greenwich.

Digits eclipsed, 3° 14'.

This eclipse will be visible principally in the Northern Polar regions, particularly in the North of America and in Greenland; and will be quite small in all that portion of the United States in which it is visible.

The phases of the eclipse for all places in the United States may be determined by means of the following table. The Sun's semi-diameter and horizontal parallax are the same as at conjunction:
