viftble Way was 8° 29' 50", which, doubled, and added 
to 31 0 26' 55", gives 48 0 2 6' 3 5", his Diftance, on 
the Limb of the Sun from the Ecliptic alfo to the South- 
ward at his Ingrefs on it ; therefore the nearcft Ap- 
proach of his Centre to that of the Sun was io' 19", and 
the Length of the Path run during the Tranjit 25' 
14", and confequently the time of running it 4 h 17', 
the half of which 2^ 8'|, fubtraded from 20 11 1 ', the 
End of the Tranjit at Greenwich , gives the Middle 
there at 17 11 52' 30", earlier by i8'y than the Series of 
Moments, &c. give it. 
Now as the faid Series makes the Middle of the 
Tranjit of 1743? at 1 ih 2! mane , and as it correfponds 
with that of 1697; and the Computation of that is 
i8'j- too late by the Series of Moments, &c. it may 
he reafonably expedted, that the fame Computation for 
this of 1743 will be fo much too late too ; and if fo, 
the Middle may be put down at 43'- paft io, or 44' 
at fartheft, Q&ober 25th in the Forenoon. 
By Computation from the Tables above-men- 
tioned, with the Corredion of the Node, I make the 
Diftance of the Centres at the neareft Approach in 
1697, to be 1 o' 3 3", but by the Obfervations of Mr. 
Wurtzelbaur it turns out only io' 19", lefs by 14". 
Should therefore their Diftance in 1743 computed in 
the fame manner at 9' 10" be as much diminifhed, 
the Duration of the Tranjit will be protraded no lefs 
than 5' 24", and thefirft Contad will be 2' 42" earlier, 
and the laft fo much later, than the Times above- 
mentioned for them. 
N.B. In the Computation of the Tranfit of 1743, 
the Semidiameter of the Sun is fiippofed 16' 14" 4, 
and that of Mercury j but in that of 1697, have 
taken
