Eclipse Of Che Sun.

| eclipse of the sun In our Atlantic States,
which was annular in part Of Texas, Lou
isiana, Mississippi, Alabama, Georgia.
South and North Carolina, Virginia, the
eastern shore of MARYLAND, and in two
towns (Nantncket and Chatham) at the
southeast extremity Of Massachusetts, in
both of which towns all of the four con-
facts of that eclipse were successfully
observed; at Nantucket by the late VIM.
Mitchell. After the usual interval of
fifty-four wears and thirty-one days, SAYS
the Boston Journal. that eclipse will re.
turn under nearly similar circumstances
and be visible throughout North Amer
lea and the adjacent Pacific and Atlantic
Oceans. except small strip south of
about Is degrees of latitude; but this
eclipse will be SO confined to these limits
that the only place outside of them in
which any part Of the observation may
be seen is the west of Ireland, where the
beginning of it will be visible few min
utes before sunset there. The line of the
central eclipse will strike the earth at
sunrise at the place in the North Pacific
in latitude 50, longitude 157, and will
reach our continent at Cape Mendocino,
in California, in latitude 40, longitude
l24, and thence pass in northeast direc-
ton over the northwest corner of that
State, over Oregon, Idaho and Montana,
to latitude 40, thence across British
America to latitude 56i, longitude 91I,
where it will be central at noon at that
place; thence 1t viii pass still in north
east direction over Hudson's Bay, Baf-
fms Bay and Greenland to latitude II,
longitude Is, where, at sunset, it will
leave the earth, having occupied two
hours and twelve minutes in crossing it.
The width Of the ring, or annular eclipse,
viii be in the United States about sew
enty miles, but no large town is included
therein, and Eureka, in California, and
B0zeman seem to be the most important
places. In our extreme Southern States.
Florida, Texas, ETC., the magnitude Of the
eclipse will be small, but constantly be-
coming larger toward the north, until
the central line is reached. In New Eng
land more than One-llalf of the sun will
be obscured; at Chicago, seven enths
at ST. Paul, five-sixths, and at the three
cities of San Francisco, Sacramento, and
Winnipeg, Manitoba each of which will
! be about $50 miles southwest of the CEN
trail line, fifteen-six:eenths. For the
computation of the beginning, end, etc
of the eclipse. the elements Of the sun
and moon, as given by Leverrier and
Hansen were used, except that the cor
rectiOns of the longitude and latitude OF
the moon suggested by Prof Newcomh
were introduced corrections which re-
tard the computed times at each place 30
to 40 seconds. The time used for these
computations is the old mean solar at
each place, and not the lately invented
method Of computations, which is some
| times called standard time"
