Hence the apparent time of conjunction at Chelsea, was OA. 41) 
55""1, which added to 44, 44’ 3"°7 gives the corresponding time at 
Greenwich 54. 25’ 588, 
The observations at Beverly were made by the Rev. President 
Willard, Doctor Prince, and Doctor Cutler. The beginning was ob- 
served by them at 11/, 1’ 48”, 114, 1’ 46”, and 114. 1 42”. The end 
at 1h, 41° 26", 1h. 4129", and 14, 41’ 23” respectively. The mean of 
these times was used. The place of observation was found by trig- 
onomietrical survey to be 1’ 43” N and 5'°6 in time E from the place 
in Salem, where I observed the eclipse of Sept. 17, 1814. Hence 
"the latitude of the place is 42° 35’ 13”, reduced 42° 23’ 47”, longitude 
58"°6 E from Cambridge, corresponding to 44, 43’ 311 W from 
Greenwich. oe

Hence the apparent time of connie at Beverly was Oh. 42’ 
38"*3, corresponding to 5h, 26’ 09’4 at Greenwich. The mean of 
this and the observation at Chelsea gives the conjunction at Greenwich 
at 54, 26 Q4"*1 apparent time, which is to be used _in finding the lon- 
gitudes of the other places of observation. 
Ifthe moon’s corrected latitude used in this calculation was too 
small by / seconds, the time of conjunction at Saves would, be 
decreased by 0° 531 seconds of time.
