in the length of the pendulum vibrating seconds. 413 
If from 50°.37 , .23 ,/ ,94 (the latitude of the summer house) 
2 8", 67 be subtracted, we have 5o 0 .Qj' .5" ,27 for the latitude 
of Dunnose by the Repeating Circle. 
The latitude of Dunnose is stated in the “ Account of the 
Trigonometrical Survey/’ to be on the supposi- 
tion of that of Greenwich being 5i 0 .28'.4o". But this latitude, 
as before stated, is found from the more recent observations 
of the present Astronomer Royal, to be 1 '',99 in excess, if the 
French refractions be employed; therefore ^o°.Qy'. 6 ", 6 i is 
the latitude of Dunnose by the Trigonometrical Survey, dif- 
fering i // ,34in excess from the result obtained by the Repeating 
Circle. 
I may here remark, that the latitude of Dunnose deduced 
from the observations made with the Repeating Circle, differs 
only o r, ,c>5 from the latitude of that station given in the first 
volume of the account of the survey, and which appears to 
have been derived trigonometrically from the latitude of 
Greenwich.
