And to conclude, we shall in all things find, that Nature does not onely
work Mechanically, but by such excellent and most compendious, as well as
stupendious contrivances, that it were impossible for all the reason in the
world to find out any contrivance to do the same thing that should have
more convenient properties. And can any be so sottish, as to think all
those things the productions of chance? Certainly, either their
Ratiocination must be extremely depraved, or they did never attentively
consider and contemplate the Works of the Al-mighty.

Observ. XXXVIII. _Of the Structure and motion of the Wings of _Flies_._
The Wings of all kinds of Insects, are, for the most part, very beautifull
Objects, and afford no less pleasing an Object to the mind to speculate
upon, then to the eye to behold. This of the blue Fly, among the rest,
wants not its peculiar ornaments and contrivances; it grows out of the
_Thorax_, or middle part of the body of a Fly, and is seated a little
beyond the center of gravity in the body towards the head, but that
_Excentricly_ is curiously balanc'd; first, by the expanded _Area_ of the
wings which lies all more backwards then the root, by the motion of them,
whereby the center of their vibration is much more backwards towards the
tail of the Fly then the root of the wing is.
