176 Solar Eclipse of July 8ih, 1843. 



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 lat. 

 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 circuit 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, Loii, Mantua, Parma, 

 Placenza, Saluzzo, Savona and Tortona in Italy; at Brixen, 

 Bruck, Clagenfurth, Judenborgh, Marburg, Trent and Yillach in 

 Austria ; at Orel, Penza and Tambow in Russia ; and that the 

 shadow will pass near the city of Nankin and the island of Chu- 

 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, to 

 the determination of the correctness of a recent suggestion, that 

 the irregularities so frequently noticed at the second and third 

 contacts 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
