176 Solar Eclipse of July 8th, 1842. 
touch the earth at sunrise, at a point in the Atlantic Ocean situ- 
ated in lat. 37° N., long. 10° W. from Greenwich, or two degrees 
west of Portugal; it thence passes across the southern part of that 
kingdom, diagonally across Spain, the south of France, Sardinia, 
Lombardy, Austria, the north of Hungary, Austrian Galicia, the 
south of European Russia, the southwest of Russia in Asia, the 
Chinese Empire and part of the North Pacific, to a point in tat. 
15° N., long. 148° E., where it will leave the earth at. sunset, 
three hours and five minutes after it first touched it, on the coast 
of Portugal, and after. describing a cireuit of about ten thousand 
miles. The width of the shadow will, as usual, vary somewhat 
in its passage across the earth, but in Italy and Germany, it will 
be a little more than one hundred geographical miles, so that if 
the path of the centre be carefully marked on a good map, and 
other lines be drawn parallel thereto, to the north and to the 
south, at the distance of about fifty miles therefrom, the places 
at which the eclipse will be total, will be easily ascertained, un- 
less situated like Venice, just within, or like Ofen, just without, the 
limit of the shadow, about which there is some doubt, in conse- 
quence of a possible difference between the tabular and observed 
latitude of the moon. In this manner it will be seen, that in 
addition to the places herein after enumerated, the eclipse will 
probably be total at St. Ubes, Evora, and Elvas in Portugal ; at 
Badajos, Truxillo, Toledo, Urgel and Gerona in Spain; at Per- 
pignan, Carcassone, Montpelier, Avignon, Nismes and Toulon in 
France; at Alessandria, Asti, Cremona, Loli, Mantua, Parma, 
Maponna, Saluzzo, Savona and Tortona in Italy; at Brixen, 
Bruck, Secon (arth, Judenburgh, Marburg, Trent and Villaeh in 
Austria; at Orel, Penza and Tambow in Russia; and that the 
shadow will pass near the city of Nankin and the islatigha Che 
san, in China, 
As the approaching eclipse will excite great interest throughout 
Europe, and especially in those places where it will be total, it is 
earnestly hoped that particular attention will be paid by those 
favorably situated, and in possession of suitable instruments, t0 
the determivation of the correctness of a recent suggestion, that 
tities so frequently noticed at the second and third 
oon of. nearly central eclipses, and at all the contacts of the 
transits of Venus, may be seen or not at the pleasure of the ob- 
server, according as the color of the dark glass, he applies to his
