The near agreement of the difference of me- 
ridians between King George’s Ifland and the four 
other places, as deduced from Captain Cook’s obferv- 
ation at the ingrefs, and from a mean of his and 
Mr. Green’s obfervations at the egrefs, fufEciently, 
I think, fliew that the obferved duration at King 
George’s Ifland is at leaft 5*^ 29' 5 ^'' 3 5 • And, from 
a comparifon made in the fame manner with the ob- 
fervations at Hudfon’s Bay, it might be fliewn that 
the time of the egrels is uncertain to a few feconds, 
owing, perhaps, to the hazinefs of the air peculiar 
to that climate, even at the altitude of 10 or 12 de- 
grees. 
By the end of the Sun’s eclipfe on the morning 
after the tranfit, the longitude of Wardhus from 
Paris, according to Father Hell, is 55' 6 " E. of 
Paris, or 2*^ 4' 22 ' E. of Greenwich : and, accord- 
ing to the obfervation of Mr. Rumoufky, Kola is 
2 ^ 2 ' 55'' E. of Paris, or 2^ 12' 1 P' E, of Green- 
wich. The point therefore at ’King George’s Ifland, 
where the tranfit was obferved, is 9*^ 57' 53'^6 
149° 28' 24'' W. of Greenwich; Vill St. Jofeph 
in California is 7^ 18' 421" — 109° 40' 37'' W. of 
Greenwich ; and Prince of Wales’s Fort in Hudfon’s 
Bay 6*^ 16' 49 1'' 94'' 12 ' 22'' W. of Green- 
wich. 
From the near agreement of the feveral refults 
before found, which are independent of the know- 
ledge of the longitude of each place, and affeded 
only by the neceffary error in obferving, the ac- 
curacy of the obfervation made at the Cape of Good 
Plope in 1761, by Meffieurs Mafon and Dixon, is 
abundantly confirmed ; -by comparing which with
