Apparent Time. Hence, allowing for the different Te- 
leicopes, the Difference of Meridians is 36/ 45 
This Emerfion at iVanJled preceded the Calculation 
by the TLables 4' 40^^* And another Emerfion obfer- 
ved with the fame Telefcope on Sept. 18, N. S. prece- 
ded the Calculation 5^ lo^f We may therefore fup- 
pofe, that on Sept. 9, N. S. the true Emerfion at Wan- 
fted preceded the cornputed about 4' 51'/. The E- 
merfion that Day by the Tables was at 12I1. 15^ 34^^ 
App. Time j therefore the true Emerfion at Wanjied 
was at i2h. lo' 42'^ At Lhhon 'twas obferved at 
iih. 34/ So that allowing for the Difference of 
Telefcopes, the Difference of Meridians by this Obfer- 
vation is 30^ 30''. 
The Mean of all thefe Differences is about 36^ 58^', 
from which fubflradting 28'' for the Difference of Me- 
ridians between London ^n^Wanfted^ the remainder will 
be tbe Difference of Meridians betw'een London and 
Lislon,v\z. 36/1=9^ 7' L, Lishon being fo much to 
the W'eftward of London. This .Difference of Longi- 
tude is about 5' f greater than what is determined in 
the forementioned Tranfa^ion.: But as the Gentlemen 
to whom we are indebted for thefe Obfervations, have 
given us hopes that they will continue to make and 
communicate more, wc need not doubt but their exadt 
Care and Diligence will foon enable us to judge yet 
more nicely of the true Situation of thofc Cities with 
refpedt to each other.
