1766 Bougainville.

In November, 1766, Commodore Bougainville sailed from France in the frigate
La Boudeuse, with the store-ship L'Etoile. After spending some time on the
coast of Brazil, and at Falkland's Islands, he got into the Pacific Sea by
the Straits of Magalhaens, in January, 1768.

In this ocean he discovered the Four Facardines, the isle of Lanciers, and
Harp Island, which I take to be the same that I afterwards named Lagoon,
Thrum Cap, and Bow Island. About twenty leagues farther to the west he
discovered four other islands; afterwards fell in with Maitea, Otaheite,
isles of Navigators, and Forlorn Hope, which to him were new discoveries.
He then passed through between the Hebrides, discovered the Shoal of Diana,
and some others, the land of Cape Deliverance, several islands more to the
north, passed the north of New Ireland, touched at 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.
