By the firft obfervations, made on Ihore, the chronometer Ihewed the
longitude to be 18° 39' 45", which was 17' 45" to the eaftward o f the truth,
and correfponded with what has been Hated before, that it was not gaining
at the rate we had allowed: further obfervations however demon-
ftrated that, although it might have been gaining lefs during the paffage,
it was now evidently gaining on its Portfmouth rate, and was found on
the 8 th of augufl: at noon, to be fall of mean time at Greenwich 17' 49"'
6"', and gaining on mean time at the rate of 9" 28"' per day. Mr. Arnold’s,
chronometer was found to have gone but indifferently on board the'
Chatham; and, at the obfervatory, it was faff of mean time at Greenwich
i h 18' 48" 6"', and gaining on mean time-at the rate- of 16" 11"' 8""
per day. The variation o f the magnetic needle, taken at the obfervatory
by our different compaffes and cards, in twenty fets of azimuths, varied
from 240 3 to 27°48'; the mean refult being 250 40' weft variation. '
The vertical inclination o f the fouth point of the magnetic needle was;

St. Helena on our return to Europe, will Be reckoned eaftward.
The latitude inferted in the following chapters, and until the 1,3th of
february, 1792, when it will be otherwife diftinguilhed,. is to be received
and confidered as fouth latitude.
The pofitive or relative durations of all Coafts, Capes, Promontories,
Illands, Rocks, Sands, Breakers, Bays, Ports, &c. & c. will' hereafter
be Hated as true, or by the world'; and thofe, bearings which will be
taken from any local fituation, whether on board the veffels, or in the
boats, will be inferted according to compafs, and be lb expreffed.

T h E nature of our voyage rendering every precaution neceffary to.
prevent, as far as was poffible, a reparation of the veffels, Mr. Brough- 1
ton, in cafe of parting, company, was provided with a lift of rendezvous;
and, the better to infure our rejoining, I now deemed it expedient
that he Ihould be furnilhed with, a copy of my inftruftions, and the route
I intended to purfue; together with ample directions, that, in the event,
o f a. total feparation, he might be enabled to carry the objeCts-of the expedition
into execution.
Although our ftay at the Cape had far exceeded my expectations, yet
I did not abandon the defign of vifiting the s.w. part of New Holland.
The feafon would probably be-too far advanced for acquiring: fo much information
as I could have wifhed, yet there Hill remained-a; fair profpeCt
of obtaining fome intelligence, which would render the talk lefs difficult to
thofe, whofe particular objeCt it might hereafter be to explore that country.
I therefore on failing out o f Falfe Bay, appointed our- next rendezvous
off,- what in the charts is called, Lyon’s Land, in about the 35th degree
of fouth latitude— in cafe of feparation to cruife there two days; and,-
not meeting with the Difcovery, then to proceed agreeably, to other nn
ftruClions.,
The Albemarle, Admiral Barrington, and Britannia tranfports bound
