'were Lent where the Eclipfe, we fuppofed, would be 
perfectly central, about 12 or 14 Miles farther North. 
A Gun from the Caftle was fired at 22 Seconds after 
Twelve, mean Time, (or 12 Minutes 22 Seconds be- 
fore Twelve, apparent Time) upon which, by Agree- 
ment, the Clocks and Watches of the Obfcrvers were 
adjufted. A fecond Cannon was difeharged precifely 
when the Eclipfe began, which was at y Minutes 3 6 
Seconds after Two. A third was difeharged when the 
annular Appearance began, which was at 2 y Minutes 
yy Seconds after Three ; its Continuation was y Mi- 
nutes 48 Seconds. A fourth Cannon was fired at the 
End of the Eclipfe, which was at 44 Minutes yo Se- 
conds after Four j ail reckoned by apparent Time. 
We had half a fcore good reflecting Telefcopes to 
make thefe Obfervations, and our Calculations per- 
fectly agreed, fo that you may depend upon than as 
molt exaCt. 
This was not done by us as a Matter of mere Curi- 
ofity, but to affift in afeertaining the Motions of the 
Moon, on Sir Ifaac Newtons Theory, upon which 
a good deal of the DoCtrine of the Longitude will 
depend. Sir Ifaac s Calculation, as to the Beginning 
of this Eclipfe, was pretty right 5 but not fo well as 
to its central Appearance. Two Spots in the Sun 
made a very diftinCt Appearance to us, as they entered 
under the Moon s Body 5 one was a little above the 
central or horizontal Line of the Sun, of this Shape 
J|j^ ; the other was near the Edge, on the Eaft Quar- 
ter. The firft, by Comparifon with the Sun's Dia- 
meter, was larger than the Disk of our Earth ; it was 
dark in the Middle, and certainly emitted no Fire or 
Light. The Edge of the Moon appeared a little rag-
