ast 4 p.m., at which time the Tide had made strong against us, and
the wind not abating, bore away, intending to have hauled under Cape St.
Diego, but was prevented by the force of the Tide, which carried us past
that Cape with surprising rapidity, at the same time caused a very great
sea. At 6, the weather being Clear, took 9, or 3 sets of, Observations of
the sun and moon in order to find the Longitude of the place, and as they
perhaps are the first Observations of this kind that were ever made so
near to the Extremity of South America, I have inserted them below just
as they were taken, that everybody may judge for themselves.
COLUMN 1: NAME OF SET.
COLUMN 2: TIME BY THE WATCH IN HOURS, MINUTES AND SECONDS.
COLUMN 3: APPARENT TIME COMPUTED FROM IN HOURS, MINUTES AND SECONDS.
COLUMN 4: OBSERVED DISTANCE. SUN AND MOON'S NEAREST LIMB IN DEGREES,
MINUTES AND SECONDS.
COLUMN 5: OBSERVED ALTITUDE. SUN'S LOWER LIMB IN DEGREES, MINUTES AND
SECONDS.
COLUMN 6: OBSERVED ALTITUDE. MOON'S UPPER LIMB IN DEGREES, MINUTES AND
SECONDS.
COLUMN 7: CORRECT ALTITUDE. SUN'S CENTER IN DEGREES, MINUTES AND SECONDS.
COLUMN 8: CORRECT ALTITUDE. MOON'S CENTER IN DEGREES, MINUTES AND
SECONDS.
COLUMN 9: THE LONGITUDE RESULTING FROM BOTH SETS OF OBSERVATIONS IN
DEGREES, MINUTES AND SECONDS.
