eoverd with Globules^ juft as if one had fpread aTi.ble 
all over with Sand j and when I view'd the fame a Jit tie 
while after, I faw the fmall Particles were coagulated 
together in irregular Figures 3 and as I did imagine be- 
fore, that the fmall Sulphureous Particles were faftned to 
the Glafs, now I faw an Oleagenous and Watry Subftance, 
which one might call the Spirit of Sulphur, drawn off 
together with the Sulphur, and that feveral places in the 
Glafs were without the Globules, and nothing but fome 
of this Oleagenous Matter to be feen. 
I had alfo a third Snail-fhell, whofe outmoft part, or 
Shell, was as fmooth as if it had been Poliftit 5 and when 
I lookt upon it thro a Microfcope, I obferved that the 
Horn or Shell had been adorn'd with wonderful Figures 5 ; 
from which fight I concluded that theGlance^orfmoothnefs. 
of the Shell was occafion'd by the long and frequent 
Attrition of the fame againft other hard Bodies, before it 
could get any Reft in the High Mountains 0 as we fee in - 
hard Stones that are found on the Sea fhore, which hf 
the frequent Motion oi the Waves or Sand about em^. 
become very fmooih and paliiht 5 and 'twas by. fucli 
Motion that the fine Figures in the Shells are quite worn 
out. 
This Shell defcribed by Fig. 5. PQjl I could break, 
very eafily with my Fingers, and with my naked Eye 
difcover that it wa& for the moft part compofed of the 
abovemention'd fhining Matter, as it was alfo for the 
moO: part full of Sulphur. 
I had another Snail-fhell, reprefented by Fig. 6. TVW^ 
which Vi/as alfo very fmooth, and when I broke that 
Shell in pieces, that which feem'd to be fo fmooth to the 
naked Eye, appeared now with as many fcratches as if it 
had been rubb'd with fharp Sand 5 and this was adornU 
with figures too that were not difcernable with the naked 
Eye 5 a fmall part of which is here defcribed by Fig. 7.
