fter the commencement of the
voyage, and was put ashore in Madagascar, where he died. One of the
objects of the voyage thus ceased to exist. The first undiscovered land
which was sighted after leaving Madagascar was named Terre d'Esperance,
and subsequently, by Cook, Prince Edward Island. Near it a collision
with the _Mascarin_ caused the partial disablement of the _Marquis de
Castries_; the search for a southern continent was therefore abandoned,
and it was resolved to visit the countries which had been discovered by
Tasman in the seventeenth century.

Crozet's first observation relating to sea-birds was made on the 8th of
January, 1772, about twelve days after leaving the Cape of Good Hope.
Terns were then in view, and thereafter, until the 13th of that month,
Terns and Gulls were frequently seen. Shortly after the latter date Du
Clesmeur, who was in command of the _Marquis de Castries_, sighted
another island which was named Ile de la Prise de Possession, and which
has been renamed Marion Island. Crozet landed upon it, and relates that
the sea-birds which were nesting upon it continued to sit on their eggs
or to feed their young regardless of his presence. There were amongst
the birds penguins, Cape petrels ('damiers'), and cormorants. Crozet
also mentions divers--'plongeons.' It is doubtful to what birds he
alludes under this name--a name which is usually applied to the
Colymbidae, a family which has no representative in the seas of the
southern hemisphere.

The terns which Crozet saw were probably of the species _Sterna
vittata_, which breeds on the islands of St. Paul and Amsterdam. It also
frequents the Tristan da Cunha Group, and Gough Island and Kerguelen
Island, so that it enjoys a wide distribution in the Southern Ocean. The
gulls may have been Dominican Gulls (_Larus dominicanus_), which are to
be found at a considerable distance from any continental land. The
penguins which frequent the seas adjacent to the islands which Marion
named Ile de la Caverne, Iles Froides, and Ile Aride are _Aptenodytes
patagonica_, _Pygoscelis papua_, _Catarrhactes chrysocome_, and
_Catarrhactes chrysolophus_. The eggs of the last-named penguin have
been found on the Ile Aride, which is now known as Crozet Island, and
the whole group as the Crozet Islands. The Cape Petrel (_Daption
capensis_) nests on Tristan da Cunha and Kerguelen Island. A Cormorant
(_Phalacrocorax verrucosus_) inhabits Kerguelen Island, but its
occurrence on
