Batavia, and arrived in
France in March, 1769.

This year was rendered remarkable by the transit of the planet Venus over
the sun's disk, a phenomenon of great importance to astronomy; and which
every-where engaged the attention of the learned in that science.

In the beginning of the 1768, the Royal Society presented a memorial to his
majesty, setting forth the advantages to be derived from accurate
observations of this transit in different parts of the world; particularly
from a set of such observations made in a southern latitude, between the
140th and 130th degrees of longitude, west from the Royal Observatory at
Greenwich; and that vessels, properly equipped, would be necessary to
convey the observers to their destined stations; but that the society were
in no condition to defray the expence of such an undertaking.

In consequence of this memorial, the Admiralty were directed by his majesty
to provide proper vessels for this purpose. Accordingly, the Endeavour
bark, which had been built for the coal-trade, was purchased and fitted out
for the southern voyage, and I was honoured with the command of her. The
Royal Society, soon after, appointed me, in conjunction with Mr Charles
Green the astronomer, to make the requisite observations on the transit.

It was at first intended to perform this great, and now a principal
business of our voyage, either at the Marquesas, or else at one of those
islands which Tasman had called Amsterdam, Rotterdam, and Middleburg, now
better known under the name of the Friendly Islands. But while the
Endeavour was getting ready for the expedition, Captain Wallis returned
from his voyage round the world, in the course of which he had discovered
several islands in the South Sea; and, amongst others, Otaheite. This
island was preferred to any of those before mentioned, on account of the
conveniences it afforded; because its place had been well ascertained, and
found to be extremely well suited to our purpose.

I was therefore ordered to proceed directly to Otaheite; and after
astronomical observations should be completed, to prosecute the design of
making discoveries in the South Pacific Ocean, by proceeding to the south
as far as the latitude of 40 deg.; then, if I found no land, to proceed to the
west between 40 deg. and 35 deg., till I fell in with New Zealand, which I was to
explore; and thence to return to England by such route as I should think
proper.
