Mr. Bowditch on the solar eclipse, Sept. V7, 1811. 267 
The moon’s longitude and latitude being corrected, the conjunc- 
tion at Salem from my observations was found to be at 2h. 13 289% 
apparent time ;_ this, added to the longitude from Greenwich, 4h. 43’ 
36""7, gives the conjunction at that place 64. 57'05"°6. By Mr. 
Lambert’s observation calculated in the same way the conjunction was 
at 2h. 13’ 32'*7, which added to the longitude 4h. 43’ 34”0 gives the 
conjunction at Greenwich 64. 57'6"*7.. The mean of the two obser- 
vations is 6h. 57’ 06"*1,* which is used in the rest of this memoir as 
the apparent time of the conjunction at Greenwich, not having any 
European observations by which that time could be obtained. 
At the time of the conjunction at Greenwich 6A. 47’ 06"71, the 
sun’s longitude by the above elements from Delambre’s tables was 
173° 56’ 32”-4, the moon’s longitude from Burg 173° 56’ 444, which 
differ 12”"0, agreeing with what was assumed above. At the same 
time the moon’s latitude by Burg was 36’ 50"*8, which decreased by 
10’°6 gives the moon’s true latitude at the time of conjunction 36 
402 N. These corrected values were used in calculating the fol- 
lowing observations. 
Observations at Nantucket by Walter Folger j jun. oe 
Sept. 17, 1811. 
The place of observation was a little to the westward of the cen- 
tre of the town of Nantucket in the latitude of 41° 15’ $2” reduced 41°
