But I conceive an other Account may be given of this 
Appearance , and that the forefaid Law of HydroBa- 
ticks is a little deficient. Tis true indeed, if we confider 
only the fpecifick Gravity of a Liquor , and the fpecifick 
Gravity of afbhd Particle floating therein, the forementio- 
ned Rule is exaft ; but in finking there is requifite a repara- 
tion of the Parts.ofthe Liquor by the finking Body ; and 
there being-a natural Inclination in the Parts of all Liquors 
to Union arifing from an Agreement or Congruity of their 
Parts, there is a refiftance therein to any thing that feparates 
this Conjundion : Now unlefs a Body have weight enough 
to overcome this Congi'uity or Union of Parts, iucha Body 
will float in a Liquor fpecifically lighter then it felf. But 
that a heavy Body, 2iS Mercury ov ^Ir on mdij have its Parts 
reduced to that Minutenefs, that their Gravity or Tenden- 
cy downwards, is not fl:rong enough to feperate the Cohefi- 
on or Union of the Parts of a Liquor, will be manifefl:, if 
we confider, that the Refifl:anee made by the Medium to a 
falling Body, is according to the Superficies of the Body ; 
but as the Body decreafts in Bulk,: its Superficies .does 
not proportionably decreafe, thus a Sphere of an Inch Dia- 
meter, has not eight times lefs Superficies than a . Sphere of 
two laches Diameter, tho' it have eight times le£s Bulk, and 
confequently pafling through 2iMediumy 2iS fuppofe Air or 
Water, the Sphere of iari Inch Diameter is, proportionably 
to its Bulk, more refifted, than a Sphere of two Inches Dia^ 
meter in proportion to its Bulk, and hence it will come to 
pafs, that at laflr i a Body may be reduced to that Minute- 
nefs,that its Gr^yitiy prefJing downwards (which is according 
to its Bulk) may be lelS than: the refiftance of the Medium^ 
which operateson the Surface of the Body .; feeing as Ilayd 
before, the Surfaces of Bodys do not decreafe fo fatt as 
their Bulks, thefedecreafingin a Tri^ /zir^^^,' but thofe in a
