rcumstances, the
error of the moon's place could not be observed at Greenwich; the
distances would therefore seem most worthy of confidence, and are
adopted; but the longitude deduced from the eclipse, as recalculated by
Mr. Crosley from _Delambre's_ solar tables of 1806, and the new lunar
tables of _Burckhardt_ of 1812, differs but very little from them: it is
135 deg. 46' 8" east.

The rates of the time keepers, deduced from equal altitudes on, and
between Feb. 27 and March 4, and their errors from mean Greenwich time,
at noon there on the last day of observation, were found to be as under:

Earnshaw's No.543 slow Oh 30' 30.54" and losing 8.43" per day.
520 slow 1h 9' 7.72" and losing 18.82" per day.

Arnold's No. 176 altered its rate prodigiously on March 1st, and on the
2nd it stopped. His watch, No. 1736, varied in its rate from 7.81" to
1.90", so that it continued to be used only as an assistant.

The longitude given by the time keepers with the King-George's-Sound
rates, on Feb. 27, the first day of observation at the tents, was by

No. 543, 136 deg. 15' 9.0" east.
520, 135 58 53.55
176, 136 1 23.95.

But by allowing a rate accelerating in arithmetic progression, from those
at King George's Sound to what were obtained at this place, the mean
longitude by the two first time keepers would be 135" 52' 16", or 7' 25"
to the east of the lunar observations; which quantity, if the positions
of the Sound and of Port Lincoln be correct, is the accumulation of their
irregularity during fifty-seven days. In laying down the coasts and
islands from the Sound up to Cape Wiles, the longitudes are taken from
the time keepers according to the accelerated rates, corrected by an
equal proportion of the error 7' 25" in fifty-seven days. From Cape Wiles
to the head of Port Lincoln the survey is made from theodolite bearings
and observed latitudes, without the aid of the time keepers.

The _Dip_ of the south end of the needle, taken at the tents, was nearly
the same as in K. George's Sound, being 64 deg. 27'
Variation of the theodolite at the same place, 1 39 E.
And the bearings from different stations in the port were conformable to
this variation, except at Cape Donington, where, at a station on the
north-western part, it appeared to be as much as 41/2 deg. east.

The observations for the variation on board the ship, at anchor in the
lower part of the port, gave 2 deg. 23' _
