even the _closest Metals_, by which means it may endeavour to _detrude_ all
earthly bodies as far from it as it can; and partly thereby, and partly by
other of its properties may move them towards the Center of the Earth. Now
that there is some such fluid, I could produce many Experiments and
Reasons, that do seem to prove it: But because it would ask some time and
room to set them down and explain them, and to consider and answer all the
Objections (many whereof I foresee) that may be alledged against it; I
shall at present proceed to other _Queries_, contenting my self to have
here only given a hint of what I may say more elswhere.
A Third _Query_ then was, Whether the _heterogeneity_ of the _ambient
fluid_ may not be accounted a _secondary cause_ of the _roundness_ or
_globular form_ of the _greater bodies_ of the world, such as are those of
the _Sun_, _Stars_, and _Planets_, the _substance_ of each of which seems
altogether _heterogeneous_ to the _circum-ambient fluid aether_? And of
this I shall say more in the Observation of the Moon.
A Fourth was, Whether the _globular form_ of the _smaller parcels_ of
matter here upon the _Earth_, as that of _Fruits_, _Pebbles_, or _Flints_,
&c. (which seem to have been a _Liquor_ at first) may not be caused by the
_heterogeneous ambient fluid_. For thus we see that melted _Glass_ will be
naturally formed into a _round Figure_; so likewise any small Parcel of any
_fusible body_, if it be perfectly enclosed by the _Air_, will be driven
into a _globular_ Form; and, when cold, will be found a _solid Ball_. This
is plainly enough manifested to us by their way of making _shot_ with the
_drops of Lead_; which being a very pretty curiosity, and known but to a
very few, and having the liberty of publishing it granted me, by that
_Eminent Virtuoso_ Sir _Robert Moray_, who brought in this Account of it to
the _Royal Society_, I have here transcribed and inserted.
To make small shot of different sizes; Communicated by his Highness _P.R._
_Take Lead out of the Pig what quantity you please, melt it down, stir and
clear it with an iron Ladle, gathering together the blackish parts that
swim at top like scum, and when you see the colour of the clear Lead to be
greenish, but no sooner, strew upon it _Auripigmentum_ powdered according
to the quantity of Lead, about as much as will lye upon a half Crown piece
will serve for eighteen or twenty pound weight of some sorts of Lead;
others will re
