(which may be seen on a
reference to Mr. Dalrymple's memoir, an extract of which accompanies
this,) to proceed to and explore the _north-west coast of New Holland_,
where, from the extreme height of the tides observed by Dampier, it is
probable that valuable harbours may be discovered.

Having performed this service, you are carefully to examine the _Gulf of
Carpentaria_, and the parts to the westward thereof, between the 130th
and 139th degrees of east longitude; taking care to seize the earliest
opportunity to do so, when the seasons and prevalent winds may be
favourable for visiting those seas.

When you shall have explored the Gulf of Carpentaria and the parts to the
westward thereof, you are to proceed to a careful investigation and
accurate survey of _Torres' Strait_, and when that shall have been
completed, you are to examine and survey the whole of the remainder of
the north, the west, and the north-west coasts of New Holland, and
especially those parts of the coast most likely to be fallen in with by
East-India ships in their outward-bound passages. And you are to examine
as particularly as circumstances will allow, the bank which extends
itself _from the Trial Rocks towards Timor_, in the hope that by
ascertaining the depth and nature of the soundings thereon, great
advantage may arise to the East-India Company's ships, in case that
passage should hereafter be frequented by them.

So soon as you shall have completed the whole of these surveys and
examinations as above directed, you are to proceed to, and examine very
carefully the _east coast_ of New Holland, seen by captain Cook, _from
Cape Flattery to the Bay of Inlets_; and in order to refresh your people,
and give the advantage of variety to the painters, you are at liberty to
touch at the _Fejees_, or some other of the islands in the _South Seas_.

During the course of the survey, you are to use the tender under your
command as much as possible; moving the Investigator onward from one
harbour to another as they shall be discovered, in order that the
naturalists may have time to range about and collect the produce of the
earth, and the painters allowed time to finish as many of their works as
they possibly can on the spot where they may have been begun: And when
you shall have completed the whole of the surveys and examinations as
abovementioned, you are to lose no time in returning with the sloop under
your command to England for farther orders, touch
