Points and fmooth fides like Diamonds, were foft at their' 
firft Coagulation, but grew greater and larger by the Ac- 
ceilion of new Matter, ’(ill they became large Grains of 
Sand 5 and moreover, that fome Diamonds were form’d 
after the fame manner. 
Now as we find, that in the Diffolution of Silver by 
Jqna fortisy fome of the fmall Silver Particles are Coa- 
gulated in Chryftals of the figure of Diamonds 5 and that 
the Sugar which is boiled to a Syrup in order to make, 
Sugar Candy, is alfo Coagulated into fuch Particles 5 fo 
we may likewife fuppofe, tharat the time when the Dia- 
mond Particles coagulate, a great deal of the fame Mat- 
ter whereof they are compofed is in the Air, but not to- 
be perceived by our naked Eye, nor theT^iantity thereof 
to be known 'till it is Coagulated into a Body ; And who 
knows but if a Shovel of that Earth, out of which they 
dig Diamonds, were brought over and carefully Exa- 
by a Microfeope, one might difeover abun- - 
dance of exa£f and compleat little Diamonds of an un- 
rpeakable fmall nefs. 
I know there are a great many People v/ho are of Opi- 
nion, that many things lying irT the Bowels of the Earthy 
and efpecially Diamonds, grow bigger and bigger, and' 
that their Increafe is occaBoned by fubterraneous Fires 
driving the Damps up higher and higher, which Damps^ 
they fay are impregnated or loaden with Mineral, Chry-- 
ftalline or Adamantine Particles.- 
But I am not Of that Opinion, for if it were true that 
an Adamantine Matter were produced by the Subterrane- 
ous Fires driving Up the Damps, we muft conclude, that, 
Ihat Matter wou’d be fluid, and then that fluidv Matter 
fo driven up, wou*d Coagulate with the Diamonds it met: 
ill its way, and make them greater y but if that were true, 
this Adamantine Matter fo driven up, cou*d not have the 
Power to diCperfe the Eanttor Sand with which the Dm- 
mond^
