Duration of the eentral eclipse on the earth, 3h 41m 21.1.

According to the Tables of Damoiseau and Burckhardt, the eclipse at the following places will be annular, and take place as follows, in mean time of the respective places :

At the following places the eclipse will not be annular. The obscuration at Halifax, N. S., Charlottetown, P. E. I., and Montreal, being on the southern side of the sun, and at the other places on the northern.

At Eastham Church, Cape Cod, Mass., in Lat. 41° 50′ 26′′, Long. 69° 58′ 40′′, the least distance of the centres (51.81) will take place at 5h 46m. 31; diff. of semidiameters 51.94; from which it appears that the line of the southern limit of the ring passes on to the Atlantic about two miles south of Nausett lights, or in Lat. 41° 49′ 37′′, Long. 69° 56' 50".

At Montreal, Canada, Lat. 45° 31', Long. 73° 35', the least distance, 62.3, will be at 5h 26m. 40 ; and as the difference of the semidiameters will be 51.5 only, the eclipse will not be annular there, but probably will be so in the southwestern extremity of Montreal Island.

The village of Saratoga Springs, N. Y., Lat. 43° 3', Long. 73° 43', appears to be situated exactly under the line of the southern limit of the ring, as the least distance of the centres (51".2), which occurs at 5h. 29m..3, is, according to the tables, the same as the difference of the semidiameters.

The difference between the absolute or Greenwich times of the beginning at Georgetown, New York, Boston, Brunswick, Charlottetown, &c., is quite small, or less than two minutes, or from 9h 10m. 27 to 9h-12 3 The time at any other place between them, and near the Atlantic, may therefore be easily ascertained with a good degree of accuracy, and without a direct computation, by subtracting its longitude from about 9h 11m, and in this manner the time of the beginning at the following cities and towns was ascertained. The angle of the point at which the first impression will be made on the sun, or at which the eclipse will commence, is reckoned from the vertex to the right hand, and that at which the obscuration will end, from the vertex to the left (except at San Francisco, where it is also to the right), as

seen through an erect telescope. For one that inverts, it is necessary

to add 180°.

At those places marked with an asterisk, the eclipse will be annular.
