'... Equidem credo, quia sit Divinitus illis
Ingenium ...'

Virg.

My Friend Sir Roger is very often merry with me upon my passing so much
of my Time among his Poultry: He has caught me twice or thrice looking
after a Bird's Nest, and several times sitting an Hour or two together
near an Hen and Chickens. He tells me he believes I am personally
acquainted with every Fowl about his House; calls such a particular Cock
my Favourite, and frequently complains that his Ducks and Geese have
more of my Company than himself.

I must confess I am infinitely delighted with those Speculations of
Nature which are to be made in a Country-Life; and as my Reading has
very much lain among Books of natural History, I cannot forbear
recollecting upon this Occasion the several Remarks which I have met
with in Authors, and comparing them with what falls under my own
Observation: The Arguments for Providence drawn from the natural History
of Animals being in my Opinion demonstrative.

The Make of every Kind of Animal is different from that of every other
Kind; and yet there is not the least Turn in the Muscles or Twist in the
Fibres of any one, which does not render them more proper for that
particular Animal's Way of Life than any other Cast or Texture of them
would have been.

The most violent Appetites in all Creatures are _Lust_ and _Hunger_: The
first is a perpetual Call upon them to propagate their Kind; the latter
to preserve themselves.

It is astonishing to consider the different Degrees of Care that descend
from the Parent to the Young, so far as is absolutely necessary for the
leaving a Posterity. Some Creatures cast their Eggs as Chance directs
them, and think of them no farther, as Insects and several Kinds of
Fish: Others, of a nicer Frame, find out proper Beds to [deposite [1]]
them in, and there leave them; as the Serpent, the Crocodile, and
Ostrich: Others hatch their Eggs and tend the Birth, 'till it is able to
shift for it self.

What can we call the Principle which directs every different Kind of
Bird to observe a particular Plan in the Structure of its Nest, and
directs all of the same Species to work after the same Model? It cannot
be Imitation; for though you hatch a Crow under a Hen, and never let it
see any of the Works of its own Kind, the Nest it makes shall be the
same, to the laying of a Stick, with all the other Ne
