broke die fore-part of v^ith my Fingers, a frhal! part 
of which, reprefented by Fig. ABC Q I placed before 
'.a Microfcope, of which BCD was what wasjoyn'd to 
the fore part of theSnail-fhelJ, and wherein I obferved fix 
prominent Particles, and five others at AE, the which 
five were fitted or infinuated into the fix Parades ^ and 
how often foever I broke the faid Shell in pieces, I flill 
obferved in the fore-part fix, and in the hind-part five 
Particles, in the fame order and difpofition 5 fo that I 
fancy it niuft have been a Licob or Part of the inclofed 
Snail, and confequently that it had been once a living 
Creature. 
Having placed one of thefe little pieces of Snail-diell 
with the Break of the fame before a Microfcope, I ob- 
ferved that the Matter within was compofed of very 
finall fhining Particles, v»'hich one would take to be 
broken pieces of Metal. 
Forafmuch as I have feen fuch like fteming Particles 
of Metal, which was really nothing but Brimftone, I 
took feme of the little pieces of the Shell, and put em 
into 3 Glaft, and then upon the Fire, and obfcrv'd, that 
in proportion to the fmalnefs of the Parts, a great deal 
of Water and Sulphur was drawn off of em, without 
difcovering the leaft fign of Metal in the remaining Black 
Matter. 
Moreover, I examined that little piece of Matter, 
which, as I faid before, 1 judged to have been 'the living 
Creature within the Shell 5 by its uncommon Weight it 
feem'd to be alfo turn'd into Metal, and the more when 
I had broken it to pieces, for then the manyfold exceed- 
ing fmall fhining Particles appear'd to be wholly Metallin. 
The abovefaid Matter v/as extraordinary hard, info-

with a Flint ftone, it yielded Sparks of Fire 5 I beat ofFa
