BIRDS o f this genus have
The bill flender and weak, in fome incurvated, in others
ftrait i noftrils minute.
Tongue very long, formed of two conjoined cylindric tubes;
miflile.
Toes three forward, one backward.
Tail confifts of ten feathers.
Legs weak.
The following are divided into two families, the one with curved
bills, the other with ftrait ones : which appears to be far better than
making two genera of them, as fome authors have done; efpecially
as they have identically the fame organs, and method of providing
themfelves with food, as well as general manners.
The ufe of the bill in moft birds is to colledt the food; burin'
this genus it feems to ferve for little other purpofe than as a cafe'
of defence for the tongue,- as it is by means of this laft alone that
it gets its nourifhment, which is ever in- a liquid ftate, and which it
draws up in the manner of the Elephant, by means of the probofcis,
or, to defcend to the leffer animals, in the common Fly, by its
trunk; though indeed neither of thefe is quite to our purpofe, but
the tongue or trunk of what is called the Hawk-Moth * is exaftly
fimilar : this laft is compofed of a double tube, and is bifid at the
end like that of a Humming-Bird; the difference is merely, that
in the laft the tongue is elongated or contracted in a ftrait direction,
defended by the bill ; in the Hawk-Moth it is Goiled up in a-
ipiral manner, like the fpring of a watch, and in this fituation is
guarded by a lateral valve on each fide. "We cannot here enter
into further particulars, as fuch a difquifition, if carried to a proper
length, would be fitter for an anatomical,, than any other de-
feription of the fu-bjecl in queftion.
