nothing so _far distant_ but may be represented to our view; and by the
help of _Microscopes_, there is nothing so _small_, as to escape our
inquiry; hence there is a new visible World discovered to the
understanding. By this means the Heavens are open'd, and a vast number of
new Stars, and new Motions, and new Productions appear in them, to which
all the ancient Astronomers were utterly Strangers. By this the Earth it
self, which lyes so neer us, under our feet, shews quite a new thing to us,
and in every _little particle_ of its matter; we now behold almost as great
a variety of Creatures, as we were able before to reckon up in the whole
_Universe_ it self.

It seems not improbable, but that by these helps the subtilty of the
composition of Bodies, the structure of their parts, the various texture of
their matter, the instruments and manner of their inward motions, and all
the other possible appearances of things, may come to be more fully
discovered; all which the ancient _Peripateticks_ were content to
comprehend in two general and (unless further explain'd) useless words of
_Matter_ and _Form_. From whence there may arise many admirable advantages,
towards the increase of the _Operative_, and the _Mechanick_ Knowledge, to
which this Age seems so much inclined, because we may perhaps be inabled to
discern all the secret workings of Nature, almost in the same manner as we
do those that are the productions of Art, and are manag'd by Wheels, and
Engines, and Springs, that were devised by humane Wit.

In this kind I here present to the World my imperfect Indeavours; which
though they shall prove no other way considerable, yet, I hope, they may be
in some measure useful to the main Design of a _reformation_ in Philosophy,
if it be only by shewing, that there it not so much requir'd towards it,
any strength of _Imagination_, or exactness of _Method_, or depth of
_Contemplation_ (though the addition of these, where they can be had, must
needs produce a much more perfect composure) as a sincere _Hand_, and a
_faithful_ Eye, to examine, and to record, the things themselves as they
appear.

And I beg my Reader, to let me take the boldness to assure him, that in
this present condition of knowledge, a man so qualified, as I have
indeavoured to be, only with resolution, and integrity, and plain
intentions of imploying his _Senses_ aright, may venture to compare the
reality and the usefulness of his services, towards the
