as bright and franfparent as any CryThi, fa ve only in thofc 
parts where they were joyried to the Stones. The Cryftal 
Particles lay very thick upon one another, and they were 
fo fmall that IGO and more were not equal to our Cryftal 
Particles 3 among others^ I obferved fomeCryftal Pardclcs 
no bigger th^n a courfe grain of Sand, ^ th^ ? which were 
eorhpdfi^d of ido other fiti'aller Pardcles, all v4ry tranfoa-

my opinion, that they were coagulated out of long Par-

I obferved, that where the little Flint Stonfes had not 
lain very dofe to one another, the void fpice,^ as it ap-

Cryftal Matter 5 but when I came to view them more nar* 
roWly, I could perceive that thofe Cryftal parts were in-

feverail fmall Cavities between them 5 from whence Icon- 
eluded, that the Flint Stones lying fo uponi'r>one another, 
as we now find 'em, a fluid CryftalliHe Matter, out .of 
which all the Gpyftals were coagulated, had infinuatcd it 
felf between thofe Flint Stones ^ and where thofe §tones 
were hoc fo clofely joyned, there did not happen to be 
enough of that Cryitalline Matter to fill up the vacant 
Ijpace, ^
