resemble it; for just after the same manner, I suppose the _pulse_ of heat
to _agitate_ the small parcels of matter, and those that are of a _like
bigness_, and _figure_, and _matter_, will _hold_, or _dance_ together, and
those which are of a _differing_ kind will be _thrust_ or _shov'd_ out from
between them; for particles that are _similar_, will, like so many _equal
musical strings equally stretcht_, vibrate together in a kind of _Harmony_
or _unison_; whereas others that are _dissimilar_, upon what account
soever, unless the disproportion be otherwise counter-ballanc'd, will, like
so many _strings out of tune_ to those unisons, though they have the same
agitating _pulse_, yet make quite _differing_ kinds of _vibrations_ and
_repercussions_, so that though they may be both mov'd, yet are their
_vibrations_ so _different_, and so _untun'd_, as 'twere to each other,
that they _cross_ and _jar_ against each other, and consequently, _cannot
agree_ together, but _fly back_ from each other to their similar particles.
Now, to give you an instance how the _disproportion_ of some bodies in one
respect, may be _counter-ballanc'd_ by a _contrary disproportion_ of the
same body in another respect, whence we find that the subtil _vinous
spirit_ is _congruous_, or does readily _mix_ with _water_, which in many
properties is of a very _differing nature_, we may consider that a _unison_
may be made either by two _strings_ of the same _bigness_, _length_, and
_tension_, or by two strings of the same _bigness_, but of _differing
length_, and a _contrary differing tension_, or _3ly._ by two strings of
_unequal length_ and _bigness_, and of a _differing tension_, or of _equal
length_, and _differing bigness_ and _tension_, and several other such
varieties. To which _three properties_ in _strings_, will correspond _three
proprieties_ also in _sand_, or the _particles_ of bodies, their _Matter_
or _Substance_, their _Figure_ or _Shape_, and their _Body_ or _Bulk_. And
from the _varieties_ of these _three_, may arise _infinite varieties_ in
fluid bodies, though all agitated by the _same pulse_ or _vibrative_
motion. And there may be as many ways of making Harmonies and Discords with
