( 89 ). 
Opportunity of determining the Longitude of that 
Fort more exactly than it can be fuppofed to be there 
done, by the bare Comparifon of the Obfervations 
with the Tables ; having two Obfervations made at 
Wayffled^ which tally with two made at Idexo tork^ on 
Aug. 25, and Sept. 10. 
By the Obfervation made Aug. 25’, 172^, O.S. which 
is efteemed the moft diftindl and beft, the Satellite E~ 
merged atph. 35^ 14' by the Clock, which went about 
4 too fad for the Apparent Time at the Emerfion, 
as appears by the Altitudes of the Sun’s Limb taken the 
Morning before and after the Obfervation ; fo that the 
Emerfion at New York was at 9h. 34^ Apparent Time ; 
that is, 9I1. 32' 20'^ Mean Time. 
Augufl 27, 8h. 40'^ Mean Time, the Satellite 
was (een emerging at Wanfled in the Refied-er ,• and 
Sept.ix^ yh. ly' 15 " M. T. ’tw^as feen emerging a- 
gain in the fame Telefcope ; So that in i5d. 22h. 19' 
3 5’'' there were 9 Emerhons ; and the Interval between 
each was about id. j8h. 28' 50". This fubhraded 
from the Time of the Emerfion obferv’d at Wan[ie^ 
Augufl 27, will give the true Emerfion at Wanfled 
on Augufl 25*, 14(1. 28' 50^/ M. T. that is, ^h. 56^ 
30 later than it was obferved at New York. 
Septernher \Q, 8 h. 10^^ by the Clock, another 
Emen'ion was obferved at New York. From the Alti- 
tudes of the Sun’s Limb taken the Morning before, I 
compute the Error of the Clock at the time of the E- 
merfion to be 1 ' 1 o^', and that the Emerfion happen’d 
at 7I1. ^9' App. T. that is, 7b. 51' Mean Time 
at New York. But fublfrading the forementioned In- 
terval of id. 18 h. "lV 50'/ from the Time of the E- 
merfion obferved at War, fled Septemler 12, 7I1. 17^ 
I ly'* M. T. we ibali have the time of the true Emer- 
fion at Wtinfled on Sept, jo, at 12I1. 48^ 25^^ M.T.
