Instance in Cassuaries.       §34. Were I to talk with any one, of a Sort of Birds, I lately saw
in St. James’s Park, about three or four Foot high, with a Covering
of something between Feathers and Hair, of a dark brown colour,
without Wings, but in the place thereof, two or three little Branches,
coming down like sprigs of Spanish Broom; long great Legs, with
Feet only of three Claws, and without a Tail; I must make this
Description of it, and so may make others understand me: But
when I am told, that the name of it is Cassuaris, I may then use that
word to stand in discourse for all my complex Idea mentioned in
that description; though by that word, which is now become a
specifick name, I know no more of the real Essence, or Constitu-
tion of that sort of Animals, than I did before; and knew probably as
much of the nature of that Species of Birds, before I learn’d the name,
as many English-men do of Swans, or Herons, which are specifick
names, very well known of sorts of Birds common in England.
