But the clock fhewed 1 o h 1 2' 44^,5 when the ftar palled, 
confequently it was 2' 28^0 too llow for mean time. 
Obfervers, who are not furnifhed with tables of the 
Sun’s right afcenlion and of the equation of time for 
the apparent noon of their meridian, may apply both 
as they are given in the Nautical Ephemeris for the meri- 
dian of the Royal Obfervatory at Greenwich ; the refult 
will be the mean time of the ftar’s palling the Greenwich 
meridian. And by applying the proportional part of the 
foregoing acceleration of 3' 5 5 ",9 1 , belonging to the dif- 
ference of longitude in time of the place of obfervation 
from Greenwich, the mean time of the ftar’s palling the 
meridian of the place of obfervation will be found. If the 
place be to the Eaft of Greenwich, the acceleration will 
be additive; if to the Weft, lubtradlive.
