a^jeatcr fpace to contain them 5 but being all faft (hut 
vp, and having no paflage thro?:gh the Pores, was the 
caufe of thofe Bodies defcrib^d by Fig: 9. 1 K, to burft into 
lb many thoufand pieces. 
Now if we refleft on the wonderful Corapofition of the 
laft namy Figure, .and the infinite number ot Salt Particles 
fhut up within it, and the various figures of the Salts that 
were extrafted from Fig. 8. we muuc lay our Fingers on 
our Mouths and cry out, O the D^pth of thefe Sxrcts. 
The abovcmention'd Gentleman gave me , amongfl 
other things, two little Dice, of the bignefs that is de- 
fcrib'd by Fig. 11, LM, adding, that (ome people faid 
they were Stone, others Bone 5 and that thefe Dice were 
found in 5'2i?///tT/W deep under Ground, and in great 
numbers in a place, where formerly there bad been 2l Rowan 
Gamp ^ and that the opinion of the Smjfers was, that the 
Roman Souldiers had made ufe of ^em in play, whilft they 
were encampt there. 
I view'd a part of one of thefe Dice, and ftruck feveral 
blows with a Hammer upon it, which indeed made Holes 
in it, but without breaking it ^ whereas if it had been 
Stone, it could not have withftood fo many blows ^ at 
laft, having cut off fome fmall bits, and made 'era glowing 
hot in the Fire, I obferv^d that it was black as Bone is, 
when it has not lain long in the Fire, and white when it lay 
longer. In my laft viewing of it, I was ftill the more 
confirmed that it was Bone, for I could then difcovcr tfie 
Pores of a Bone in it 5 yet, in my opinion, it could not 
be made of the Bone of an Ox, becaufethe Parts were 
fmaller.
