For the side _A_ is
_detruded_ to _E_ by the _Gravity_, and _B_ to _F_ by the _resistance_ of
the subjacent medium: and therefore _C_ must necessarily be thrust to _G_;
and _D_ to _H_. Or else, supposing a greater _gravity_ in the _ambient_, by
whose more then ordinary _pressure_ against the under side of the included
globule; _B_ will be forced to _F_, and by its _resistance_ of the motion
_upwards_, the side _A_ will be _deprest_ to _E_, and therefore _C_ being
thrust to _G_ and _D_ to _H_; the _globular_ Figure by this means also will
be made an _Elliptico-spherical_. Next if a fluid be included _partly_ with
one, and _partly_ with another fluid, it will be found to be shaped
_diversly_, according to the proportion of the _gravity_ and _incongruity_
of the 3 _fluids_ one to another: As in the _second Figure_, let the upper
_MMM_ be _Air_, the middle _LMNO_ be common _Oyl_, the lower _OOO_ be
_Water_, the _Oyl_ will be form'd, not into a _spherical_ Figure, such as
is represented by the _pricked Line_, but into such a Figure as LMNO, whose
side LMN will be of a flatter _Elliptical_ Figure, by reason of the great
disproportion between the _Gravity_ of _Oyl_ and _Air_, and the side LOM of
a rounder, because of the smaller difference between the weight of _Oyl_
and _Water_. Lastly, The _globular_ Figure will be changed, if the
_ambient_ be partly _fluid_ and partly _solid_.
