Kingfton in Jamaica, which came to my Hands 
fome time fince. They were made by Alexander 
Macfarlane Efq; of Kingfton in Jamaica, a Fellow 
of this Society, who is provided with a complete 
Apparatus of aftronomical Inftruments, which he 
purchafed of Colin Campbell Efq;. As this Gentle- 
man is well verfed both in the Theory and Pradice 
of Aftronomy, I think the following Obfervations 
may be depended on for fixing the Longitude of 
Kingfton ; efpecially as we have the fame Obfer- 
vations made at the Houfe of Mr. George Graham 
in Fleetftreet, London , and already publifhed in the

By the firlt Oblervation of the Eclipfe of the Moon, 
compared with the fame Eclipfe obferved here, 
Kingfton is found to be 5“ 6' 2" to the Weft of 
London. 
And by the Tranftt of Mercury neglecting his 
Parallax, Kingfton is found to be 5 h 7' 33". 
This laft is the molt to be depended on for fet-
