Karakakooa Bay, for determining its latitude and longitude, and for finding
the rate and error of the time-keeper. To these are subjoined the mean
variation of the compass, the dip of the magnetic needle, and a table of
the latitude and longitude of the Sandwich Islands.


The latitude of the observatory, deduced
from meridian zenith distances of the
sun, eleven stars to the south, and four
stars to the north of the zenith 19° 28' 0" N.
The longitude of the observatory, deduced
from 253 sets of lunar observations;
each set consisting of six observed
distances of the moon from the
sun or stars; 14 of the above sets were
only taken at the observatory, 105 sets
being taken whilst cruising off Owhyhee,
and 134 sets when at Atooi and
Oneeheow, all these being reduced to
the observatory, by means of the timekeeper 204° 0' 0" E.
The longitude of the observatory, by the
time-keeper, on the 19th January,
1779, according to its rate, as found
at Greenwich 214° 7' 15' E.
The longitude of the observatory, by the
time-keeper, on the 19th January,
1779, according to its rate, corrected
at different places, and last at Samganoodha
Harbour, in Oonalaschka 203° 37' 22" E.
