The mean of the azimuths of the westerly point at 7^ 30™ 
in the evening is 81° 28', and of the easterly at the same 
time 80® 48' ; so that to reduce the situations of the westerly 
and easterly points to their distances from what ought to 
be considered as their meridian, 20' must be subtracted 
from each of the azimuths of the westerly point, and added 
to each of those of the easterly, similarly to what was done 
with the observations made in doors. The mean of the ob- 
servations gives the position of the south point at the same 
hour o'.4 W., or so nearly in the meridian, that the obser- 
vations of this point require no reduction. The observed
