The central eclipse will begin on the earth at sunrise, in lat. 434°, 
Greenwich time, in Salisbury, in the northeastern extremity of 
Massachusetts, in lat. 42° 52 57’, long. 70° 50’ 5”; it thence passes 
in an E.S.E. course across the Atlantic, reaching Africa in lat. 17° 
longest will be 3" 395, but in Salisbury, Mass., and the adjacent 
town of Seabrook, N. H., 3" 17°2°. 
The distance between the northern and southern limits of the 
annular eclipse in New York and New England will be about 110 
miles, and a line drav a map, from Watertown, N. Y. about 
five miles south of Middlebury, Vt., and three south of Portland, 
Me., will represent very nearly the northern limit, and another 
drawn five miles north of Ithaca and of Hudson, N. Y., over 
Hadley, Franklin, Duxbury and Truro, Mass., the southern. Be- 
tween these lines are included a large part of central New York 
east o 
southern half of Vermont and New Hampshire, and the south- 
western extremity of York and part of Cumberland counties, 
Maine ; also five astronomical observatories, viz: those of Hamilton 
College near Utica, and at Albany, in New York, at Harvard Unt- 
ampshire ; but the eclipse will not be annular at Vassar 
College, Poughkeepsie, in any part of Connecticut or Rhode 
—— at Springfield, Fall River or New Bedford, Mass., Middle- 
i ve : 
two seconds only. 
ince the magnificent total eclipse of five minutes duration, at 
Boston and Albany, near noon of June 16th, 1806, there have 
been in New England only two central eclipses, both annular in
