Longitude of Lancaster west of Greenwich. . . 5 04 39 



If we suppose the eclipse to have commenced at Lancaster 

 12" earlier, which Mr. Ellicott suspected, in this case the dif- 

 ference of meridians between the Havanna and Lancaster will 

 be 24'. 25". and it would result that Lancaster was west of 

 Greenwich 5 h . 04'. 51,"; differing from my result only 12", 

 which is as near as can be expected ; for as this determination 

 depends upon the exactness of the theory of the moon, it can- 

 not be relied on within 30" of time. 



These observations may be very important to compare with 

 others of the same eclipse, which may have been made in 

 other observatories.
