thin Maffes, appearing like Nubeculi^^ or Clouds in the 
Water y which grow more thick and opah^ by the con-

mean an higher and more faturate Green, as the Matter 
thickens and encreafes. That this matter inclines fo much 
to that Colour y is the lefs ftrange, fince we fee fo large a 
fliare of it, when confti rating Vegetables, wearing the 
fame Colour in them. But if there be any eonfiderabie- 
quantity of meer Mineral Matter in the Water, thisy be- 
ing of a greater fpecifick gravity than the Vegetable^ as 
the F articles of it unite and combine in fuch Number, till 
they form ^ Molecula, the impetus of whofe Gravity fur- 
palTes that of the Refijiance of the Water, fubfides a great 
deal of it to the bottom. Nor does it only fall down if 
felf but, frequently entangling with ihQ Vegetable Nu^ 
beculce^ forces them down along with it. 
The reafon why Bodies, when diffolved and reduced 
to extreme fmall parts, are fuftain'd in Liquors that are 
of lefs fpecifick Gravity than thofe Bodies are, hath been 
pointed at by a late ingenious Member of this Society •f'. f Mr. w^. 
He is indeed far from having adjufted all the Momenta^^!j''^*'j^> 
of this affair J however it muft be admitted, that, i^j^o^i^u'^^' 
the dividing or folution of Bodies, their Surfaces do not 
decreafe in the fame Proportion that their Bulk- does.
