contacts Of that eclipse were successfully
observed; ct Nantucket by the late
William Mitchell. After the usual inter-
val Of ffty-four years and thirty -one
days, says the Boston Journal, that
eclipse will return under nearly similar
circumstances and be visible throughout
North America and the adjacent Pacific
and Atlantic oceans. except q small strip
south Of about sixteen degrees oflaflkude;
but this eclipse will be 80 confined to
these limits that the only place
outside Of them in which any part of the
obscuration may be seen in the west of
Ireland, where the beginning Of it will be
visible few minutes before sunset there.
The line of the central eclipse will strike
the earth at sunrise at the place IN the |
north Pacific, in latitude 36, longitude
157, and will reach our continent at Cape
Nendocino, in California, in latitude 40,
longitude 1A, and thence pass in north
east direction over the northwest corner
Of that state, over Oregon, Idaho and
Montana, to latitude 49, thence across
British America to latitude 564, longi-
tude 9lH, where it will be central at
noon at that place; thence, it will pass
sons bay, Batfn's bay and Greenland to
latitude IL, longitude Is, where, at sun
set, it will leave the earth, having oc-
cupied two hours and ten minutes in
crossing it. The width of the ring. or
annular eclipse, will be in the United
States about seventy miles, but no large
town is included therein, and Eureka, in
California, and Bozeman, in Montana,
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 becoming
larger, toward the north until the cen.
trail line is reached. In New England
more than one-han OF the sun will be
obscured; at Chicago, seven.tenths; at
st. Paul, five-slxths, and at the three
cities of San Francisco, Sacramento,
and Winnipeg. Manitoba, each of which
will be about $50 miles southwest of the
central line, ffteen-sixteenths. For the
computation of the beginning, end, ETC.,
of the eclipse, the elements Of the sun
J and moon, as given by Leverrier and
Hansen, we're used, except that the cor
rections of the longitude and latitude
OF the moon suggested by Professor
/. Newcome were introduced; corrections
! which retard the computed times at each
place thirty to forty seconds. The time
used foI these computations is the old
]. lately invented method of computations
which is sometimes called '.standard
