on . . . a very
noble bird, larger than the common swan, and equally beautiful
in form . . . its wings were edged with white: the bill was
tinged with red."

1790. J. White, `Voyage to New South Wales,' p. 137:

"We found nine birds, that, whilst swimming, most perfectly
resembled the <i>rara avis</i> of the ancients, a black swan."

1802. G. Barrington, `History of New South Wales,' p. 146:

"Large ponds covered with ducks and black swans."

1847. J. D. Lang, `Phillipsland,' p. 115:

"These extensive sheets of glassy water . . . were
absolutely alive with black swans and other water fowl . . .
There must have been at least five hundred swans in view at one
time on one of the lakes. They were no `rara avis' there."

1848. J. Gould, `Birds of Australia,' vol. vii. pl. 6:

"<i>Cygnus Atratus</i>, Black Swan. The first notice on record
respecting the existence of the Black Swan occurs in a letter
written by Mr. Witsen to Dr. M. Lister about the year 1698, in
which he says, `Here is returned a ship, which by our East
India Company was sent to the south land called <i>Hollandea
Nova</i>'; and adds that Black Swans, Parrots and many Sea-Cows
were found there."

1856. J. S. Mill, `Logic' [4th edition], vol. i. bk. iii.
c. iii. p. 344:

"Mankind were wrong, it seems, in concluding that all swans
were white. . . . As there were black swans, though civilized
people had existed for three thousand years on the earth
without meeting with them."

1875. `Spectator' (Melbourne), May 29, p. 45, col. 3:

"The presence of immense flocks of black swans is also regarded
as an indication of approaching cold weather."

"The musical whoop of the black swan is sometimes heard as the
wedge-shaped flock passes over."

1895. G. Metcalfe, `Australian Zoology,' p. 64:

"Strzelecki states that the black swan was discovered in 1697
by Vlaming. . . . In 1726 two were brought alive to Batavia,
having been procured on the West Coast of Australia, near Dirk
Hartog's Bay. Captain Cook observed it on several parts of the
coast."
