Mr. Bowditch on the solar eclipse, Oct. 27, 1780. 283 
_ Hence the apparent time of conjunction was at 1h. 13’ 33’"0, which 
subtracted from the time of conjunction at Greenwich leaves the lon- 
gitude of the place of observation 44. 12’ 311. 
An increase of /seconds in the moon’s latitude, would decrease the 
time of conjunction 0°46 / seconds of time, which subtracted from 
the corresponding correction at Beverly and Chelsea leaves *07 /, which 
is the number of seconds of time to be subtracted from the longitude 
of Charlotte-town for an increase of / seconds in the moon’s latitude, 
and as this correction is very small, there can be but ate uncertainty 
in the longitude on this account. 
Observations at Newport and Providence Oct. 27, 1780. 
_ The beginning of the eclipse was not observed at these places. 
The end was observed at Newport, R. I. by Mr. Granchain, at 1A. 
40’ 41” apparent time. He states the latitude of the place to be 41° 
30’ 30". Hollond makes it 41° 28'28”. The mean is nearly 41° 293’* 
which used as the true latitude makes the reduced latitude 41° 18’ 7”, 
the reduction of the moon’s equatorial parallax 5’-24, the ()—O) 
par. in long.—1’ 432, in latitude 51’ 21”*3, D’s augmented semidi- 
ameter 16’ 29°09. Hence the conjunctions at Newport was at OA. 
40’ 58”°7 apparent time. The difference of meridians ot Newportand 
Providence according to Hollond’s survey is 18"*8, which would make 
the conjunction at Providence by this observation 0A. 40’ 39”-9. 
The end of the eclipse at Providence, by the observations of 
Messrs. Brown and West was at 14. 39’ 08"*3 apparent time. ‘The 
latitude of the place by Hollond is 41° 48’ 50”, reduced 41°37’ 26". 
* This difference in the latitude is scarcely sensible in the computation of 
the longitude from this observation, since an increase of one minute in the lati- 
tude decreases the longitude but half a second oftime. The: same is to be observ- 
ed of the observation at Providence.
