eclipse which will happen on the 18th Of
February, will be one Of the most remark
able that will again be Witnessed in the
U.States for q long course ofyears. The
apparent diameter Of the sun will be 81
l-a minutes in degree, that Of the moon
81 l-2. OF course the eclipse will be an
aular; that is in all places where the sun
will be centrally eclipsed, at the moment Of
the greatest obscurration, it will exhibit
the appearance of a beautiful luminous
ring about the moon. Eclipses of this
kind are Of less frequent occurrence than
those which are total. Tho centre of the
eclipse will first touch the earth's disk in
the great Pacific Ocean on the morning
of Feb. 18th in lat. IS deg. 55 minutes
N. and Ion. 14O deg. minutes west from
Greenwich. AT this point the sun will
rise centrally eclipsed at "a minutes past
6. O'Clock; or at hours 81 min. r. nj.
apparent time at Greenwich. Thence
proceeding by genlle curve to the South
and East in i6 minutes it will enter upon
the coast of California, in lat 81 deg. 80
minute N. Thence curving Northward-
", Al minutes more it will enter the u.
States near the S. w. corner of Louisia-
ma, and in minutes will cross the Mis-
sissippi, Alabama and Georgia, in 81
minutes more it will arrive at a point in
Pendleton county, South Carolina, in lat.
"a degrees 81 minutes N. lon. SO deg. 3S
min. w. where the sun will be centrally
eclipsed on the meridian. Thence pass
ing over North Carolina into Virginia, in
Id minutes it will cross James River, near
Richmond, and continuing in nearly di-
rect line, in minutes will leave the Jer-
sey shore at Little Eggharbor, passing
few miles east of Montauk Point; in 8
minutes it will leave the eastern shore Of
Cape Cod at Wellfeet, and in s minutes
will enter upon the southwestern extrem-
ity Of Nova Scotia. Thence, passing ov-
er the island Of Newfoundland, and increas
ing in velocity, as it approaches the verge
Of the earth; in 10 minutes more it will
leave its disk in lat. 81 degrees. SO deg.
40 min. w. lon. at which point the sun
will set central eclipsed at Al. 80 min. or
6h. 25m. Greenwich time.
The eclipse will have been Oh. 81 m. in
crossing the earth's disk, and about one
hour from it's entrance to the time of its
leaving the United States. A line drawn
through the above points on the Map of
North America, will pass through all those
places where the eclipse is central. Two
other lines on each fthe first at distance
Of SO miles, will include all places in the
United States where it will be Annular.
Its penumbira will precede and follow the,
centre, at the Mean internal of one hour
and thirty minutes, making on the central
tract the beginning and end ofthe eclipse.
Lines drawn on map ofthe United States,
parallel to the central tract at intervals,
on the S. side of 200, 1876 and Tx miles,
and on the north at intervals of225, 25O,
and three hundred miles will exhibit, near
ly, the respective points where the sun
will be II, 10, and digits eclipsed. BY
making portions along the central path Of
the eclipse, ofthe intervals Of Greenwich
time and protracting the hour lines at right
angles, the time and phases Of the eclipse
may be found for nearly any place in the
u. States; observing to reduce the Green
wich time to that ofthe place Of observa-
ton.
This eclipse will be visible over every
part ofthe North American continent and
the West Indies, and will be seen as far
south as the city of Quito in South Amer
ica.
