he wisdom and providence of the Creator; for not onely the same
kind of creature may be produc'd from several kinds of ways, but the very
same creature may produce several kinds: For, as divers Watches may be made
out of several materials, which may yet have all the same appearance, and
move after the same manner, that is, shew the hour equally true, the one as
the other, and out of the same kind of matter, like Watches, may be wrought
differing ways; and, as one and the same Watch may, by being diversly
agitated, or mov'd, by this or that agent, or after this or that manner,
produce a quite contrary effect: So may it be with these most curious
Engines of Insect's bodies; the All-wise God of Nature, may have so ordered
and disposed the little _Automatons_, that when nourished, acted, or
enlivened by this cause, they produce one kind of effect, or animate shape,
when by another they act quite another way, and another Animal is produc'd.
So may he so order several materials, as to make them, by several kinds of
methods, produce similar _Automatons_.

But to come to the Description of this Insect, as it appears through a
_Microscope_, of which a representation is made in the 28. _Scheme_. Its
head A, is exceeding small, in proportion to its body, consisting of two
clusters of pearl'd eyes BB, on each side of its head, whose pearls or
eye-balls are curiously rang'd like those of other Flies; between these, in
the forehead of it, there are plac'd upon two small black balls, CC, two
long jointed horns, tapering towards the top, much resembling the long
horns of Lobsters, each of whose stems or quills, DD, were brisled or
brushed with multitudes of small stiff hairs, issuing out every way from
the several joints, like the strings or sproutings of the herb
_Horse-tail_, which is oft observ'd to grow among Corn, and for the whole
shape, it does very much resemble those _brushy Vegetables_; besides these,
there are two other jointed and brisled horns, or feelers, EE, in the
forepart of the head, and a _proboscis_, F, underneath, which in some Gnats
are very long, streight hollow pipes, by which these creatures are able to
drill and penetrate the skin, and thence, through those pipes suck so much
bloud as to stuff their bellies so full till they be ready to burst.

This small head, with its appurtenances, is fastned on by a short neck, G,
to the middle of the _thorax_, which is large, and seems cased with a
strong black shel, HIK,
