has a motion composed of both,
and, using its wings as sails, makes great speed.

Vasta velut Libyae venantum vocibus ales
Cum premitur, calidas cursu transmittit arenas,
Inque modum veli sinuatis flamine pennis
Pulverulenta volat.

Claud. in Eutr.

32 Xenophon says, Cyrus had horses that could overtake the goat and the
wild ass; but none that could reach this creature. A thousand golden
ducats, or a hundred camels, was the stated price of a horse that
could equal their speed.

33 Though this bird is but just mentioned in my author, I could not
forbear going a little farther, and spreading those beautiful plumes
(which are there shut up) in half a dozen lines. The circumstance I
have marked of his opening his plumes to the sun is true. Expandit
colores adverso maxime sole, quia sic fulgentius radiant. Plin. l.
x. c. 20.

34 Thyanus (de Re Accip.) mentions a hawk that flew from Paris to
London in a night.

And the Egyptians, in regard to its swiftness, made it their symbol
for the wind; for which reason we may suppose the hawk, as well as
the crow above, to have been a bird of note in Egypt.

35 The eagle is said to be of so acute a sight, that when she is so
high in air that man cannot see her, she can discern the smallest
fish under water. My author accurately understood the nature of the
creatures he describes, and seems to have been a naturalist as well
as a poet, which the next note will confirm.

36 The meaning of this question is, Knowest thou the time and
circumstances of their bringing forth? For to know the time only was
easy, and had nothing extraordinary in it; but the circumstances had
something peculiarly expressive of God's providence, which makes the
question proper in this place. Pliny observes, that the hind with
young is by instinct directed to a certain herb called Seselis,
which facilitates the birth. Thunder also (which looks like the more
immediate hand of Providence) has the same effect. Ps. xxix. In so
early an age to observe these things, may style our author a
naturalist.

37 Pursuing their prey by night is true of most wild beasts,
particularly the lion. Ps. cvi. 20. The Arabians have one among
