be remov’d, which may be found from 
the Unevennefs of the Stone, or fromo-s

not determine? and it is not cogent,vyhai 
is alledged of Water indofed in Chry- 
ftals, fince ’tis certain, that there is Air 
included as well as Water jand that there 
are many Chryftals including Air alone ? 
But then, if Chryftal were concreted in 
an Aqueous fluid, all fpaccs, every where 
clos’d up, would be full of Water, fee¬

that Water thus (hut up did never va-

This Jplace is afforded to Chryftal by 
the Hollowneftes of Stones, varioufly 
produced. Nor doth it hinder, that 
whole Hillocks are made up of Earthy 
matter very full of Qhryftaljbecaufe that 
near the fame Hillocks are found ftony 
Mountains, apt to produce Chryftals j 
and even in thofe very hillocks of Earthy 
matter there are digged out very big 
Stones, broken off from the neighbour¬ 
ing Mountains; fome of which have fif- 
iures filled up with Marble-matter, juft
