points connecting the cusps, continued twelve or fifteen seconds. Mr. 

 Blunt did not see the dark lines described by Francis Bailey, Esq. 

 though favourably circumstanced for such an observation. Mr. Walker 

 had found for the longitude of Mr. Blunt's observatory, from the be- 

 ginning of the eclipse of 1836, 4h. 55m. 52.95s. and 4h. 56m. 2.07s. 

 from the end:— Mean result, 4h. 55m. 57.51s. Mr. E. O. Kendall 

 had found from the eclipse of 1838, a mean result of 4h. 56m. 1.16s. 

 The mean, by the two eclipses, was 4h. 55m. 59.34s.; which makes 

 the longitude of the City Hall, New York, 4h. 56m. 3.7s. Mr. Paine, 

 in the American Almanac, makes the same 4h. 56m. 4.5s.; and 

 Mr. E. I. Dent, by transportation of four chronometers from the Green- 

 wich Observatory to New York, and again to Greenwich, finds for 

 the same 4h. 56m. 4.42s. The mean of the three determinations is 

 4h. 56m. 4.2s.
