and _unite_
with them: but _roul_ off from _Wood_, _Stone_, _Glass_, &c. if never so
little scituated out of its _horizontal level_; and _water_ that will _wet
salt_ and _dissolve_ it, will _slip_ off from _Tallow_, or the like,
without at all _adhering_; as it may likewise be observed to do upon a
_dusty_ superficies. And next they cause the parts of _homogeneal fluid_
bodies readily to _adhere_ together and _mix_, and of _heterogeneal_, to be
exceeding _averse_ thereunto. Hence we find, that _two_ small _drops_ of
_water_, on any superficies they can roul on, will, if they chance to touch
each other, _readily unite_ and _mix_ into one 3d _drop_: The like may be
observed with two small _Bowls_ of _Quick-silver_ upon a Table or Glass,
provided their surfaces be not _dusty_; and with two drops of _Oyl_ upon
fair water, _&c_. And further, _water_ put unto _wine_, _salt water_,
_vinegar_, _spirit_ of _wine_, or the like, does immediately (especially if
they be shaken together) _disperse_ it self all over them. Hence, on the
contrary, we also find, that _Oyl of Tartar_ poured upon _Quick-silver,_
and _Spirit of Wine_ on that _Oyl_, and _Oyl of Turpentine_ on that
_Spirit_, and _Air_ upon that _Oyl_, though they be stopt closely up into a
Bottle, and _shaken_ never so much, they will by no means long suffer any
of their bigger parts to be _united_ or included within any of the other
Liquors (by which recited Liquors, may be plainly enough represented the
four _Peripatetical Elements_, and the more subtil _AEther_ above all.
